Tryptophan Health Dictionary

Tryptophan: From 2 Different Sources


(1) One of the nine indispensable (essential) AMINO ACIDS. Like other amino acids, tryptophan is needed by the body to synthesise the proteins necessary for its growth and functioning. The description indispensable – previously the adjective used was essential – is applied because the body is unable to manufacture these amino acids, which have to be obtained from food or drink.

(2) A drug that has helped some patients with resistant DEPRESSION. Used as a supporting drug with other treatment, tryptophan was withdrawn because of side-effects; it has, however, been reintroduced for use in hospital for patients for whom no alternative treatment is suitable. (See also MENTAL ILLNESS.)

Pellagra

A potentially fatal nutritional disorder caused by a de?ciency of vitamin B complex (niacin). The symptoms are DERMATITIS, diarrhoea and DEMENTIA. The de?ciency occurs mainly in poor people in developing countries where maize is a prime constituent of the diet. Nicotinic acid in maize is in a bound form that the consumer cannot utilise. Further, maize is de?cient in the amino acid, tryptophan, from which the human body can make nicotinic acid (see AMINO ACIDS).

Treatment The disease is prevented or cured by adding to the diet, foods such as fresh meat, eggs, milk, liver, and yeast extracts, as well as nicotinic acid – in addition to improving the general conditions of life.... pellagra

About the Nutrients in This Food Beans are seeds, high in complex carbohydrates including starch and dietary fiber. They have indigestible sugars (stachyose and raffinose), plus insoluble cellulose and lignin in the seed covering and soluble gums and pectins in the bean. The proteins in beans are limited in the essential amino acids methionine and cystine.* All beans are a good source of the B vitamin folate, and iron. One-half cup canned kidney beans has 7.5 g dietary fiber, 65 mcg folate (15 percent of the R DA), and 1.6 mg iron (11 percent of the R DA for a woman, 20 percent of the R DA for a man). Raw beans contain antinutrient chemicals that inactivate enzymes required to digest proteins and carbohydrates. They also contain factors that inactivate vitamin A and also hemagglutinins, substances that make red blood cells clump together. Cooking beans disarms the enzyme inhibi- tors and the anti-vitamin A factors, but not the hemagglutinins. However, the amount of hemagglutinins in the beans is so small that it has no mea- surable effect in your body. * Soybeans are t he only beans t hat contain proteins considered “complete” because t hey contain sufficient amounts of all t he essent ial amino acids.

The Most Nutritious Way to Serve This Food Cooked, to destroy antinutrients. With grains. The proteins in grains are deficient in the essential amino acids lysine and isoleucine but contain sufficient tryptophan, methionine, and cystine; the proteins in beans are exactly the opposite. Together, these foods provide “complete” proteins. With an iron-rich food (meat) or with a vitamin C-rich food (tomatoes). Both enhance your body’s ability to use the iron in the beans. The meat makes your stomach more acid (acid favors iron absorption); the vitamin C may convert the ferric iron in beans into ferrous iron, which is more easily absorbed by the body.

Diets That May Restrict or Exclude This Food Low-calcium diet Low-fiber diet Low-purine (antigout) diet

Buying This Food Look for: Smooth-skinned, uniformly sized, evenly colored beans that are free of stones and debris. The good news about beans sold in plastic bags is that the transparent material gives you a chance to see the beans inside; the bad news is that pyridoxine and pyridoxal, the natural forms of vitamin B6, are very sensitive to light. Avoid: Beans sold in bulk. Some B vitamins, such as vitamin B6 (pyridoxine and pyridoxal), are very sensitive to light. In addition, open bins allow insects into the beans, indicated by tiny holes showing where the bug has burrowed into or through the bean. If you choose to buy in bulk, be sure to check for smooth skinned, uniformly sized, evenly colored beans free of holes, stones, and other debris.

Storing This Food Store beans in air- and moistureproof containers in a cool, dark cabinet where they are pro- tected from heat, light, and insects.

Preparing This Food Wash dried beans and pick them over carefully, discarding damaged or withered beans and any that float. (Only withered beans are light enough to float in water.) Cover the beans with water, bring them to a boil, and then set them aside to soak. When you are ready to use the beans, discard the water in which beans have been soaked. Some of the indigestible sugars in the beans that cause intestinal gas when you eat the beans will leach out into the water, making the beans less “gassy.”

What Happens When You Cook This Food When beans are cooked in liquid, their cells absorb water, swell, and eventually rupture, releasing the pectins and gums and nutrients inside. In addition, cooking destroys antinutri- ents in beans, making them more nutritious and safe to eat.

How Other Kinds of Processing Affect This Food Canning. The heat of canning destroys some of the B vitamins in the beans. Vitamin B is water-soluble. You can recover all the lost B vitamins simply by using the liquid in the can, but the liquid also contains the indigestible sugars that cause intestinal gas when you eat beans. Preprocessing. Preprocessed dried beans have already been soaked. They take less time to cook but are lower in B vitamins.

Medical Uses and/or Benefits Lower risk of some birth defects. As many as two of every 1,000 babies born in the United States each year may have cleft palate or a neural tube (spinal cord) defect due to their moth- ers’ not having gotten adequate amounts of folate during pregnancy. The current R DA for folate is 180 mcg for a woman and 200 mcg for a man, but the FDA now recommends 400 mcg for a woman who is or may become pregnant. Taking a folate supplement before becoming pregnant and continuing through the first two months of pregnancy reduces the risk of cleft palate; taking folate through the entire pregnancy reduces the risk of neural tube defects. Lower risk of heart attack. In the spring of 1998, an analysis of data from the records for more than 80,000 women enrolled in the long-run ning Nurses Health Study at Har vard School of Public Health/ Brigham and Woman’s Hospital in Boston demonstrated that a diet providing more than 400 mcg folate and 3 mg vitamin B6 a day from either food or supple- ments, more than t wice the current R DA for each, may reduce a woman’s risk of heart attack by almost 50 percent. A lthough men were not included in the analysis, the results are assumed to apply to them as well. NOT E : Beans are high in B6 as well as folate. Fruit, green leaf y vegetables, whole grains, meat, fish, poultr y, and shellfish are good sources of vitamin B6. To reduce the levels of serum cholesterol. The gums and pectins in dried beans and peas appear to lower blood levels of cholesterol. Currently there are two theories to explain how this may happen. The first theory is that the pectins in the beans form a gel in your stomach that sops up fats and keeps them from being absorbed by your body. The second is that bacteria in the gut feed on the bean fiber, producing short-chain fatty acids that inhibit the production of cholesterol in your liver. As a source of carbohydrates for people with diabetes. Beans are digested very slowly, produc- ing only a gradual rise in blood-sugar levels. As a result, the body needs less insulin to control blood sugar after eating beans than after eating some other high-carbohydrate foods (such as bread or potato). In studies at the University of Kentucky, a bean, whole-grain, vegetable, and fruit-rich diet developed at the University of Toronto enabled patients with type 1 dia- betes (who do not produce any insulin themselves) to cut their daily insulin intake by 38 percent. Patients with type 2 diabetes (who can produce some insulin) were able to reduce their insulin injections by 98 percent. This diet is in line with the nutritional guidelines of the American Diabetes Association, but people with diabetes should always consult with their doctors and/or dietitians before altering their diet. As a diet aid. Although beans are high in calories, they are also high in bulk (fiber); even a small serving can make you feel full. And, because they are insulin-sparing, they delay the rise in insulin levels that makes us feel hungry again soon after eating. Research at the University of Toronto suggests the insulin-sparing effect may last for several hours after you eat the beans, perhaps until after the next meal.

Adverse Effects Associated with This Food Intestinal gas. All legumes (beans and peas) contain raffinose and stachyose, complex sug- ars that human beings cannot digest. The sugars sit in the gut and are fermented by intestinal bacteria which then produce gas that distends the intestines and makes us uncomfortable. You can lessen this effect by covering the beans with water, bringing them to a boil for three to five minutes, and then setting them aside to soak for four to six hours so that the indigestible sugars leach out in the soaking water, which can be discarded. Alternatively, you may soak the beans for four hours in nine cups of water for every cup of beans, discard the soaking water, and add new water as your recipe directs. Then cook the beans; drain them before serving. Production of uric acid. Purines are the natural metabolic by-products of protein metabo- lism in the body. They eventually break down into uric acid, sharp cr ystals that may concentrate in joints, a condition known as gout. If uric acid cr ystals collect in the urine, the result may be kidney stones. Eating dried beans, which are rich in proteins, may raise the concentration of purines in your body. Although controlling the amount of purines in the diet does not significantly affect the course of gout (which is treated with allopurinol, a drug that prevents the formation of uric acid cr ystals), limiting these foods is still part of many gout regimens.

Food/Drug Interactions Monoamine oxidase (MAO) inhibitors. Monoamine oxidase inhibitors are drugs used to treat depression. They inactivate naturally occurring enzymes in your body that metabolize tyramine, a substance found in many fermented or aged foods. Tyramine constricts blood vessels and increases blood pressure. If you eat a food containing tyramine while you are taking an M AO inhibitor, you cannot effectively eliminate the tyramine from your body. The result may be a hypertensive crisis. Some nutrition guides list dried beans as a food to avoid while using M AO inhibitors.... beans

Bread

Nutritional Profile Energy value (calories per serving): Moderate Protein: Moderate Fat: Low to moderate Saturated fat: Low to high Cholesterol: Low to high Carbohydrates: High Fiber: Moderate to high Sodium: Moderate to high Major vitamin contribution: B vitamins Major mineral contribution: Calcium, iron, potassium

About the Nutrients in This Food All commercially made yeast breads are approximately equal in nutri- tional value. Enriched white bread contains virtually the same amounts of proteins, fats, and carbohydrates as whole wheat bread, although it may contain only half the dietary fiber (see flour). Bread is a high-carbohydrate food with lots of starch. The exact amount of fiber, fat, and cholesterol in the loaf varies with the recipe. Bread’s proteins, from grain, are low in the essential amino acid lysine. The most important carbohydrate in bread is starch; all breads contain some sugar. Depending on the recipe, the fats may be highly saturated (butter or hydrogenated vegetable fats) or primarily unsaturated (vegetable fat). All bread is a good source of B vitamins (thiamin, riboflavin, niacin), and in 1998, the Food and Drug Administration ordered food manufactur- ers to add folates—which protect against birth defects of the spinal cord and against heart disease—to flour, rice, and other grain products. One year later, data from the Framingham Heart Study, which has followed heart health among residents of a Boston suburb for nearly half a cen- tury, showed a dramatic increase in blood levels of folic acid. Before the fortification of foods, 22 percent of the study participants had a folic acid deficiency; after, the number fell to 2 percent. Bread is a moderately good source of calcium, magnesium, and phos- phorus. (Breads made with milk contain more calcium than breads made without milk.) Although bread is made from grains and grains contain phytic acid, a natural antinutrient that binds calcium ions into insoluble, indigestible compounds, the phytic acid is inactivated by enzyme action during leavening. Bread does not bind calcium. All commercially made breads are moderately high in sodium; some contain more sugar than others. Grains are not usually considered a good source of iodine, but commer- cially made breads often pick up iodine from the iodophors and iodates used to clean the plants and machines in which they are made. Homemade breads share the basic nutritional characteristics of commercially made breads, but you can vary the recipe to suit your own taste, lowering the salt, sugar, or fat and raising the fiber content, as you prefer.

The Most Nutritious Way to Serve This Food As sandwiches, with cheese, milk, eggs, meat, fish, or poultry. These foods supply the essen- tial amino acid lysine to “complete” the proteins in grains. With beans or peas. The proteins in grains are deficient in the essential amino acids lysine and isoleucine and rich in the essential amino acids tryptophan, methionine, and cystine. The proteins in legumes (beans and peas) are exactly the opposite.

Diets That May Restrict or Exclude This Food Gluten-free diet (excludes breads made with wheat, oats, rye, buckwheat and barley flour) Lactose-free diet Low-fiber diet (excludes coarse whole-grain breads) Low-sodium diet

Buying This Food Look for: Fresh bread. Check the date on closed packages of commercial bread.

Storing This Food Store bread at room temperature, in a tightly closed plastic bag (the best protection) or in a breadbox. How long bread stays fresh depends to a great extent on how much fat it contains. Bread made with some butter or other fat will keep for about three days at room tempera- ture. Bread made without fat (Italian bread, French bread) will dry out in just a few hours; for longer storage, wrap it in foil, put it inside a plastic bag, and freeze it. When you are ready to serve the French or Italian bread, you can remove it from the plastic bag and put the foil- wrapped loaf directly into the oven. Throw away moldy bread. The molds that grow on bread may produce carcinogenic toxins. Do not store fresh bread in the refrigerator; bread stales most quickly at temperatures just above freezing. The one exception: In warm, humid weather, refrigerating bread slows the growth of molds.

When You Are Ready to Serve This Food Use a serrated knife to cut bread easily.

What Happens When You Cook This Food Toasting is a chemical process that caramelizes sugars and amino acids (proteins) on the surface of the bread, turning the bread a golden brown. This chemical reaction, known both as the browning reaction and the Maillard reaction (after the French chemist who first identified it), alters the structure of the surface sugars, starches, and amino acids. The sugars become indigestible food fiber; the amino acids break into smaller fragments that are no longer nutritionally useful. Thus toast has more fiber and less protein than plain bread. How- ever, the role of heat-generated fibers in the human diet is poorly understood. Some experts consider them inert and harmless; others believe they may be hazardous.

How Other Kinds of Processing Affect This Food Freezing. Frozen bread releases moisture that collects inside the paper, foil, or plastic bag in which it is wrapped. If you unwrap the bread before defrosting it, the moisture will be lost and the bread will be dry. Always defrost bread in its wrappings so that it can reabsorb the moisture that keeps it tasting fresh. Drying. Since molds require moisture, the less moisture a food contains, the less likely it is support mold growth. That is why bread crumbs and Melba toast, which are relatively mois- ture-free, keep better than fresh bread. Both can be ground fine and used as a toasty-flavored thickener in place of flour or cornstarch.

Medical Uses and/or Benefits A lower risk of some kinds of cancer. In 1998, scientists at Wayne State University in Detroit conducted a meta-analysis of data from more than 30 well-designed animal studies mea- suring the anti-cancer effects of wheat bran, the part of grain with highest amount of the insoluble dietary fibers cellulose and lignin. They found a 32 percent reduction in the risk of colon cancer among animals fed wheat bran; now they plan to conduct a similar meta- analysis of human studies. Breads made with whole grain wheat are a good source of wheat bran. NOTE : The amount of fiber per serving listed on a food package label shows the total amount of fiber (insoluble and soluble). Early in 1999, however, new data from the long-running Nurses Health Study at Brigham Women’s Hospital/Harvard University School of Public Health showed that women who ate a high-fiber diet had a risk of colon cancer similar to that of women who ate a low fiber diet. Because this study contradicts literally hundreds of others conducted over the past 30 years, researchers are awaiting confirming evidence before changing dietary recommendations. Calming effect. Mood is affected by naturally occurring chemicals called neurotransmitters that facilitate transmission of impulses between brain cells. The amino acid tryptophan amino acid is the most important constituent of serotonin, a “calming” neurotransmitter. Foods such as bread, which are high in complex carbohydrates, help move tryptophan into your brain, increasing the availability of serotonin.

Adverse Effects Associated with This Food Allergic reactions and/or gastric distress. Bread contains several ingredients that may trigger allergic reactions, aggravate digestive problems, or upset a specific diet, among them gluten (prohibited on gluten-free diets); milk (prohibited on a lactose- and galactose-free diet or for people who are sensitive to milk proteins); sugar (prohibited on a sucrose-free diet); salt (controlled on a sodium-restricted diet); and fats (restricted or prohibited on a controlled-fat, low-cholesterol diet).... bread

Bitter gourd or Carilla fruit is a branched climbing annual which is cultivated throughout India. It is a monoecious plant with angled and grooved stems and hairy or villous young parts. Tendrils are simple, slender and elongate. Leaves are simple, orbicular, cordate and deeply divided into 5-7 lobes. Flowers are unisexual, yellow and arranged on 5-10cm long peduncles. Fruits are 5-15cm long with 3-valved capsules, pendulous, fusiform, ribbed and beaked bearing numerous triangular tubercles. Seeds are many or few with shining sculptured surface. The roots are useful in coloptosis and ophthalmopathy. The leaves are useful in vitiated conditions of pita, helminthiasis, constipation, intermittent fever, burning sensation of the sole and nyctalopia. The fruits are useful in skin diseases, leprosy, ulcers, wounds, burning sensation, constipation, anorexia, flatulence, colic, helminthiasis, rheumatalgia, gout, diabetes, asthma, cough, dysmenorrhoea, impurity of breast milk, fever and debility. Seeds are useful in the treatment of ulcers, pharyngodynia, and obstructions of the liver and spleen. The leaves and fruits are used for external application in lumbago, ulceration and bone fractures and internally in leprosy, haemorrhoids and jaundice (Warrier et al, 1995). The drug improves digestion, calms down sexual urge, quells diseases due to pitta and kapha and cures anaemia, anorexia, leprosy, ulcers, jaundice, flatulence and piles. Fruit is useful in gout, rheumatism and complaints of liver and spleen (Nadkarni, 1954; Aiyer and Kolammal, 1966; Mooss, 1976; Kurup et al, 1979). Kaccoradi taila is an important preparation using the drug (Sivarajan et al, 1994).

The seeds give triterpene glycosides, named momordicosides A, B, C, D and E, which are glycosides of cucurbit-5-en-triol, tetraol or pentaol. Leaves and vines give tetracyclic triterpenes-momordicines I, II and III (bitter principles). Immature fruits give several non-bitter and 2 bitter cucurbitacin glycosides.

Colocynth or Bitter apple is found, cultivated and wild, throughout India in warmer areas. It is an extensively trailing annual herb with bifid tendrils angular branching stems and wooly tender shoots. Leaves are deeply divided, lobes narrow thick, glabrous or somewhat hairy. Flowers are unisexual, yellow, both males and females solitary and with pale-yellow corolla. Fruit is a globose or oblong fleshy indehiscent berry, 5-7.5cm in diameter and variegated with green and white. Seeds are pale brown. The fruits are useful in tumours, ascites, leucoderma, ulcers, asthma, bronchitis, urethrorrhea, jaundice, dyspepsia, constipations, elephantiasis, tubercular glands of the neck and splenomegaly (Warrier et al, 1994). It is useful in abnormal presentations of the foetus and in atrophy of the foetus. In addition to the above properties, the root has a beneficial action in inflammation of the breasts, pain in the joints; externally it is used in ophthalmia and in uterine pains. The fruit and root, with or without is rubbed into a paste with water and applied to boils and pimples. In rheumatism, equal parts of the root and long pepper are given in pill. A paste of the root is applied to the enlarged abdomen of children (Kirtikar and Basu, 1988). The fruit is useful in ascites, biliousness, jaundice, cerebral congestion, colic, constipation dropsy, fever, worms and sciatica. Root is given in cases of abdominal enlargement, cough, asthma, inflammation of the breast, ulcers, urinary diseases and rheumatism. Oil from seeds is used for poisonous bites, bowel complaints, epilepsy and also for blackening the hair (Nadkarni, 1954; Dey, 1980). The important formulations using the root and fruit are Abhayarista, Mahatiktakam kasaya, Manasamitravatakam, Cavikasava, Madhuyastyadi taila, etc. (Sivarajan et al, 1994). The powder is often used as an insecticide. The extract should never be given without some aromatic to correct its griping tendency (Nadkarni, 1998).

Fruit contains a glycoside- colocynthin, its aglycone- -elaterin, citrulluin, citrullene and citrullic acid. Unripe fruit contains p-hydroxy benzyl methyl ester. Roots contain - elaterin and hentriacontane (Husain et al, 1992). Colocynth is, in moderate doses, drastic, hydrogogue, cathartic and diuretic. In large doses, it is emetic and gastro-intestinal irritant and in small doses, it is expectorant and alterative. Colocynthin is a cathartic and intensely bitter principle. It has a purgative action. All parts of the plant are very bitter. The fruit has been described as cathartic (Nadkarni, 1982).

C. vulgaris var. fistulosus Duthie & Fuller. syn. C. fistulosus has its fruit about the size of small turnip, the seeds of which are used medicinally. The fruit is tasteless when unripe and sweet when ripe. The unripe fruit is used to cure jaundice. Ripe fruit cures kapha and vata and causes biliousness. It is good for sore eyes, scabies and itching. The seeds are tonic to the brain and used as a cooling medicine. An emulsion of the seeds is made into a poultice with the pounded leaves and applied hot in cases of intestinal inflammations (Kirtikar and Basu, 1988). Fruit juice is good in quenching thirst and it is used as an antiseptic in typhus fever with cumin and sugar. It is used as a cooling drink in strangury and affections of urinary organs such as gonorrhoea; in hepatic congestion and intestinal catarrh. The bitter watermelon of Sind is known as “Kirbut” and is used as a purgative.

Seeds yield a fixed oil and proteids; citrullin. Seeds are cooling, demulcent, diuretic, vermifuge and nutritive. Pulp is cooling and diuretic. Fruit-juice is cooling and refreshing (Nadkarni, 1982).

Pompion or Pumpkin is a climbing herb which is considered to be a native of America and cultivated in many parts of India. The stem and leaves are with a harsh prickly armature. Foliage is stiff, more or less rigid and erect. Leaves are with a broad triangular pointed outline and often with deep lobes. Corolla is mostly with erect or spreading (not drooping) pointed lobes, the tube narrowing towards the base. Peduncle is strongly 5-angled and little or much expanding near the fruit. The fruit is cooling and astringent to the bowels, increases appetite, cures leprosy, ‘kapha and vata’, thirst, fatigue and purifies the blood. The leaves are used to remove biliousness. Fruit is good for teeth, throat and eyes and allays thirst. Seeds cure sore chests, haemoptysis, bronchitis and fever. It is good for the kidney and brain. The leaves are used as an external application for burns. The seeds are considered anthelmintic. The seeds are largely used for flavouring certain preparations of Indian hemp, and the root for a nefarious purpose, viz., to make the preparation more potent. The seeds are taeniacide, diuretic and demulcent. The fruit is cooling, laxative and astringent. The leaves are digestible, haematinic and analgesic.

The other important species belonging to the genus Cucurbita is C. maxima Duchena, the seeds of which are a popular remedy for tape-worm and oil as a nervine tonic (Kirtikar & Basu, 1988).

Corallocarpus is a prostrate or climbing herb distributed in Punjab, Sind, Gujarat, Deccan, Karnataka and Sri Lanka. It is monoecious with large root which is turnip-shaped and slender stem which is grooved, zigzag and glabrous. Tendrils are simple, slender and glabrous. Leaves are sub-orbicular in outline, light green above and pale beneath, deeply cordate at the base, angled or more or less deeply 3-5 lobed. Petiole is long and glabrous. Male flowers are small and arranged at the tip of a straight stiff glabrous peduncle. Calyx is slightly hairy, long and rounded at the base. Corolla is long and greenish yellow. Female flowers are usually solitary with short, stout and glabrous peduncles. Fruit is stalked, long, ellipsoid or ovoid. Seeds are pyriform, turgid, brown and with a whitish corded margin. It is prescribed in later stages of dysentery and old veneral complaints. For external use in chronic rheumatism, it is made into a liniment with cumin seed, onion and castor oil. It is used in case of snakebite where it is administered internally and applied to the bitten part. The root is given in syphilitic rheumatism and later stages of dysentery. The plant is bitter, sweet, alexipharmic and emetic. The root is said to possess alterative and laxative properties (Kirtikar and Basu, 1988). Root contains a bitter principle like Breyonin (Chopra et al, 1980).

Agrotechnology: Cucurbits can be successfully grown during January-March and September- December. For the rainfed crop, sowing can also be started after the receipt of the first few showers.

Pits of 60cm diameter and 30-45cm depth are to be taken at the desired spacing. Well rotten FYM or vegetable mixture is to be mixed with topsoil in the pit and seeds are to be sown at 4-5/pit. Unhealthy plants are to be removed after 2 weeks and retained 2-3 plants/pit. FYM is to be applied at 20-25t/ha as basal dose along with half dose of N (35kg/ha) and full dose of P (25kg) and K (25kg). The remaining dose of N (35kg) can be applied in 2 equal split doses at fortnightly intervals. During the initial stages of growth, irrigation is to be given at an interval of 3-4 days and at alternate days during flowering and fruiting periods. For trailing cucumber, pumpkin and melon, dried twigs are to be spread on the ground. Bitter gourd, bottle gourd, snake gourd and ash gourd are to be trailed on Pandals. Weeding and raking of the soil are to be conducted at the time of fertilizer application. Earthing up may be done during rainy season. The most dreaded pest of cucurbits is fruit flies which can be controlled by using fruit traps, covering the fruits with polythene, cloth or paper bags, removal and destruction of affected fruits and lastly spraying with Carbaryl or Malathion 0. 2% suspension containing sugar or jaggery at 10g/l at fortnightly intervals after fruit set initiation. During rainy season, downy mildew and mosaic diseases are severe in cucurbits. The former can be checked by spraying Mancozeb 0.2%. The spread of mosaic can be checked by controlling the vectors using Dimethoate or Phosphamidon 0.05% and destruction of affected plants and collateral hosts. Harvesting to be done at least 10 days after insecticide or fungicide application (KAU,1996).... cucurbits

Indispensable Amino Acids

Nutritional Profile Energy value (calories per serving): Moderate Protein: Moderate Fat: Low Saturated fat: Low Cholesterol: None Carbohydrates: High Fiber: High Sodium: Low Major vitamin contribution: Vitamin A (in yellow corn), B vitamins, vitamin C Major mineral contribution: Potassium

About the Nutrients in This Food Like other grains, corn is a high-carbohydrate, high-fiber food. Eighty-one percent of the solid material in the corn kernel consists of sugars, starch, and dietary fiber, including insoluble cellulose and noncarbohydrate lignin in the seed covering and soluble pectins and gums in the kernel.* Corn has small amounts of vitamin A, the B vitamin folate, and vitamin C. Corn is a moderately good source of plant proteins, but zein (its major protein) is deficient in the essential amino acids lysine, cystine, and tryptophan. Corn is low in fat and its oils are composed primarily of unsaturated fatty acids. Yellow corn, which gets its color from the xanthophyll pigments lutein and zeaxanthin plus the vitamin A-active pigments carotene and cryptoxanthin, contains a little vitamin A; white corn has very little. One fresh ear of yellow corn, 5.5– 6.5 inches long, has three grams dietar y fiber, one gram fat (0.1 g saturated fat, 0.3 g monounsaturated fat, 0.4 mg polyunsaturated fat), 137 IU vitamin A (6 percent of the R DA for a woman, 5 percent of the R DA for a man), 34 mcg folate (9 percent of the R DA), and 5 mg vitamin C (7 percent of the R DA for a woman, 6 percent of the R DA for a man). * The most plent iful sugar in sweet corn is glucose; hydrolysis (chemical splitt ing) of corn starch is t he principal indust rial source of glucose. Since glucose is less sweet t han sucrose, sucrose and fructose are added to commercial corn syrup to make it sweeter.

The Most Nutritious Way to Serve This Food With beans (which are rich in lysine) or milk (which is rich in lysine and tryptophan), to complement the proteins in corn. With meat or a food rich in vitamin C, to make the iron in corn more useful.

Diets That May Restrict or Exclude This Food Low-fiber diet

Buying This Food Look for: Cobs that feel cool or are stored in a refrigerated bin. Keeping corn cool helps retain its vitamin C and slows the natural conversion of the corn’s sugars to starch. Choose fresh corn with medium-sized kernels that yield slightly when you press them with your fingertip. Very small kernels are immature; very large ones are older and will taste starchy rather than sweet. Both yellow and white kernels may be equally tasty, but the husk of the corn should always be moist and green. A dry yellowish husk means that the corn is old enough for the chlorophyll pigments in the husk to have faded, letting the carotenes underneath show through.

Storing This Food Refrigerate fresh corn. At room temperature, fresh-picked sweet corn will convert nearly half its sugar to starch within 24 hours and lose half its vitamin C in four days. In the refrigera- tor, it may keep all its vitamin C for up to a week and may retain its sweet taste for as long as ten days.

Preparing This Food Strip off the husks and silk, and brush with a vegetable brush to get rid of clinging silky threads. R inse the corn briefly under running water, and plunge into boiling water for four to six minutes, depending on the size of the corn.

What Happens When You Cook This Food Heat denatures (breaks apart) the long-chain protein molecules in the liquid inside the corn kernel, allowing them to form a network of protein molecules that will squeeze out moisture and turn rubbery if you cook the corn too long. Heat also allows the starch granules inside the kernel to absorb water so that they swell and eventually rupture, releasing the nutrients inside. When you cook corn, the trick is to cook it just long enough to rupture its starch granules while keeping its protein molecules from turning tough and chewy. Cooking fresh corn for several minutes in boiling water may destroy at least half of its vitamin C. At Cornell University, food scientists found that cooking fresh corn in the microwave oven (two ears/without water if very fresh/4 minutes/600 –700 watts) preserves most of the vitamin C.

How Other Kinds of Processing Affect This Food Canning and freezing. Canned corn and frozen corn both have less vitamin C than fresh- cooked corn. The vitamin is lost when the corn is heated during canning or blanched before freezing to destroy the natural enzymes that would otherwise continue to ripen it. Blanch- ing in a microwave oven rather than in boiling water can preserve the vitamin C in frozen corn (see above). Milling. Milling removes the hull and germ from the corn kernel, leaving what is called hominy. Hominy, which is sometimes soaked in wood ash (lye) to increase its calcium con- tent, can be dried and used as a cereal (grits) or ground into corn flour. Coarsely ground corn flour is called cornmeal. Processed corn cereals. All processed, ready-to-eat corn cereals are much higher in sodium and sugar than fresh corn. Added calcium carbonate. Pellagra is a niacin-deficiency disease that occurs most com- monly among people for whom corn is the staple food in a diet lacking protein foods with the essential amino acid tryptophan, which can be converted to niacin in the human body. Pellagra is not an inevitable result of a diet high in corn, however, since the niacin in corn can be made more useful by soaking the corn in a solution of calcium carbonate (lime) and water. In Mexico, for example, the corn used to make tortillas is boiled in a dilute solution of calcium carbonate (from shells or limestone) and water, then washed, drained, and ground. The alkaline bath appears to release the bound niacin in corn so that it can be absorbed by the body.

Medical Uses and/or Benefits As a wheat substitute in baking. People who are allergic to wheat or cannot tolerate the glu- ten in wheat flour or wheat cereals can often use corn flour or hominy instead. Bath powder. Corn starch, a fine powder refined from the endosperm (inner part) of the corn kernel, can be used as an inexpensive, unperfumed body or face powder. Because it absorbs oils, it is also used as an ingredient in dry shampoos.

Adverse Effects Associated with This Food Allergic reaction. According to the Merck Manual, corn is one of the 12 foods most likely to trigger the classic food allergy symptoms: hives, swelling of the lips and eyes, and upset stomach. The others are berries (blackberries, blueberries, raspberries, strawberries), choco- late, eggs, fish, legumes (green peas, lima beans, peanuts, soybeans), milk, nuts, peaches, pork, shellfish, and wheat (see wheat cer ea ls).... corn

Gelatin

Nutritional Profile Energy value (calories per serving): Low Protein: Low Fat: Low Saturated fat: Low Cholesterol: Low Carbohydrates: None Fiber: None Sodium: Low Major vitamin contribution: None Major mineral contribution: None

About the Nutrients in This Food Although gelatin is made from the collagen (connective tissue) of cattle hides and bones or pig skin, its proteins are limited in the essential acid tryptophan, which is destroyed when the bones and skin are treated with acid, and is deficient in several others, including lysine. In fact, gelatin’s proteins are of such poor quality that, unlike other foods of animal origin (meat, milk), gelatin cannot sustain life. Laboratory rats fed a diet in which gelatin was the primary protein did not grow as they should; half died within 48 days, even though the gelatin was supplemented with some of the essential amino acids. Plain gelatin has no carbohydrates and fiber. It is low in fat. Flavored gel- atin desserts, however, are high in carbohydrates because of the added sugar.

The Most Nutritious Way to Serve This Food With a protein food rich in complete proteins. Gelatin desserts whipped with milk fit the bill.

Diets That May Restrict or Exclude This Food Low-carbohydrate diet (gelatin desserts prepared with sugar) Low-sodium diet (commercial gelatin powders) Sucrose-free diet (gelatin desserts prepared with sugar) * Values are for prepared unsweetened gelat in.

Buying This Food Look for: Tightly sealed, clean boxes.

Storing This Food Store gelatin boxes in a cool, dry cabinet.

Preparing This Food Commercial unflavored gelatin comes in premeasured 1-tablespoon packets. One tablespoon of gelatin will thicken about two cups of water. To combine the gelatin and water, first heat ¾ cup water to boiling. While it is heating, add the gelatin to ¼ cup cold liquid and let it absorb moisture until it is translucent. Then add the boiling water. (Flavored fruit gelatins can be dissolved directly in hot water.)

What Happens When You Cook This Food When you mix gelatin with hot water, its protein molecules create a network that stiffens into a stable, solid gel as it squeezes out moisture. The longer the gel sits, the more intermo- lecular bonds it forms, the more moisture it loses and the firmer it becomes. A day-old gel is much firmer than one you’ve just made. Gelatin is used as a thickener in prepared foods and can be used at home to thicken sauces. Flavored gelatin dessert powders have less stiffening power than plain gelatin because some of their protein has been replaced by sugar. To build a layered gelatin mold, let each layer harden before you add the next.... gelatin

Importance: Indian ginseng or Winter cherry is an erect branching perennial undershrub which is considered to be one of the best rejuvenating agents in Ayurveda. Its roots, leaves and seeds are used in Ayurvedic and Unani medicines, to combat diseases ranging from tuberculosis to arthritis. The pharmacological activity of the plant is attributed to the presence of several alkaloids and withaniols. Roots are prescribed in medicines for hiccup, several female disorders, bronchitis, rheumatism, dropsy, stomach and lung inflammations and skin diseases. Its roots and paste of green leaves are used to relieve joint pains and inflammation. It is also an ingredient of medicaments prescribed for curing disability and sexual weakness in male. Leaves are used in eye diseases. Seeds are diuretic. It is a constituent of the herbal drug ‘Lactare’ which is a galactagogue.

Aswagandha was observed to increase cell-mediated immunity, prevent stress induced changes in adrenal function and enhance protein synthesis. Milk fortified with it increases total proteins and body weight. It is a well known rejuvenating agent capable of imparting long life, youthful vigour and intellectual power. It improves physical strength and is prescribed in all cases of general debility. Aswagandha powder (6-12g) twice a day along with honey and ghee is advised for tuberculosis in Sushruta Samhita. It also provides sound sleep (Prakash, 1997).

Distribution: Aswagandha is believed to have oriental origin. It is found wild in the forests of Mandsaur and Bastar in Mandhya Pradesh, the foot hills of Punjab, Himachal Pradesh, Uttar Pradesh and western Himalayas in India. It is also found wild in the Mediterranean region in North America. In India it is cultivated in Madhya Pradesh, Rajastan and other drier parts of the country.

Botany: Aswagandha belongs to the genus Withania and family Solanaceae. Two species, viz, W. coagulans Dunal and W. somnifera Dunal are found in India. W. coagulans is a rigid grey under shrub of 60-120cm high. W. somnifera is erect, evergreen, tomentose shrub, 30-75cm in height. Roots are stout, fleshy, cylindrical, 1-2cm in diameter and whitish brown in colour. Leaves are simple, ovate, glabrous and opposite. Flowers are bisexual, inconspicuous, greenish or dull yellow in colour born on axillary umbellate cymes, comprising 5 sepals, petals and stamens each; the two celled ovary has a single style and a bilobed stigma. The petals are united and tubular. The stamens are attached to the corolla tube and bear erect anthers which form a close column or cone around the style. Pollen production is poor. The fruit is a small berry, globose, orange red when mature and is enclosed in persistent calyx. The seeds are small, flat, yellow and reniform in shape and very light in weight. The chromosome number 2n = 48.

The cultivated plants have sizable differences from the wild forms not only in their morphological characters but also in the therapeutical action, though the alkaloids present are the same in both (Kaul, 1957). Some botanists, therefore, described the cultivated plant distinct from wild taxa and have coined a new name W. aswagandha (Kaul, 1957) which is contested by Atal and Schwarting (1961).

Agrotechnology: Asgandh is a tropical crop growing well under dry climate. The areas receiving 600 to 750mm rainfall is best suited to this crop. Rainy season crop requires relatively dry season and the roots are fully developed when 1-2 late winter rains are received. Sandy loam or light red soils having a pH of 7.5- 8.0 with good drainage are suitable for its cultivation. It is usually cultivated on poor and marginal soils. Withania is propagated through seeds. It is a late kharif crop and planting is done in August. Seeds are either broadcast-sown or seedlings are raised in nursery and then transplanted. Seed rate is 10-12 kg/ha for broadcasting and 5kg/ha for transplanting. In direct sown crop plants are thinned and gap filling is done 25-30 days after sowing. Seeds should be treated with Dithane M-45 at 3g/kg of seeds before sowing. Seeds are sown in the nursery just before the onset of rainy season and covered with light soil. Seeds germinate in 6-7 days. When seedlings are six weeks old they are transplanted at 60cm in furrows taken 60cm apart. The crop is mainly grown as a rainfed crop on residual fertility and no manure or fertilizers are applied to this crop generally. However, application of organic manure is beneficial for realizing better yields. It is not a fertilizer responsive crop. One hand weeding 25-30 days after sowing helps to control weeds effectively. No serious pest is reported in this crop. Diseases like seedling rot and blight are observed. Seedling mortality becomes serious under high temperature and humid conditions. The disease can be minimized by use of disease free seeds and treatment with thiram or deltan at 3-4g/kg seed before sowing. Further, use of crop rotation, timely sowing and keeping field well drained also protect the crop. Spraying with 0.3% fytolan, dithane Z-78 or dithane M-45 will help controlling the disease incidence. Spraying is repeated at 15 days interval if the disease persists. Aswagandha is a crop of 150-170 days duration. The maturity of the crop is judged by the drying of the leaves and reddening of berries. Harvesting usually starts from January and continues till March. Roots, leaves and seeds are the economical parts. The entire plant is uprooted for roots, which are separated from the aerial parts. The berries are plucked from dried plants and are threshed to obtain the seeds. The yield is 400-500kg of dry roots and 50-75kg seeds per hectare.

Post harvest technology: The roots are separated from the plant by cutting the stem 1-2cm above the crown.

Roots are then cut into small pieces of 7-10cm to facilitate drying. Occasionally, the roots are dried as a whole. The dried roots are cleaned, trimmed, graded, packed and marketed. Roots are carefully hand sorted into the following four grades.

Grade A: Root pieces 7cm long, 1-1.5cm diameter, brittle, solid, and pure white from outside.

Grade B: Root pieces 5cm long, 1cm diameter, brittle, solid and white from outside.

Grade C: Root pieces 3-4cm long, less than 1cm diameter and solid. Lower grade: Root pieces smaller, hollow and yellowish from outside.

Properties and activity: Aswagandha roots contain alkaloids, starch, reducing sugar, hentriacontane, glycosides, dulcital, withaniol acid and a neutral compound. Wide variation (0.13-0.31%) is observed in alkaloid content. Majumdar (1955) isolated 8 amorphous bases such as withanine, somniferine, somniferinine, somnine, withananine, withananinine, pseudowithanine and withasomnine. Other alkaloids reported are nicotine, tropine, pseudotropine, 3, -tigloyloxytropane, choline, cuscudohygrine, anaferine, anahygrine and others. Free aminoacids in the roots include aspartic acid, glycine, tyrosine, alanine, proline, tryptophan, glutamic acid and cystine. Leaves contain 12 withanolides, alkaloids, glycosides, glucose and free amino acids. Berries contain a milk coagulating enzyme, two esterases, free amino acids, fatty oil, essential oil and alkaloids. Methods for alkaloid’s analysis in Asgandh roots have also been reported (Majumdar, 1955; Mishra, 1989; Maheshwari, 1989). Withania roots are astringent, bitter, acrid, somniferous, thermogenic, stimulant, aphrodisiac, diuretic and tonic. Leaf is antibiotic, antitumourous, antihepatotoxic and antiinflammatory. Seed is milk coagulating, hypnotic and diuretic.... indian ginseng

The pulp of ripe fruit (50 g/rat per day) given daily with standard food pellets prevented increase in blood pressure in deoxycorticosterone-in- duced hypertension in rats. This was found partially related to increased serotonin levels triggered by the high carbohydrate and tryptophan content of the fruit.

Dietary fibre prepared from unripe banana exerted an antiatherogenic effect, keeping the levels of cholesterol in serum and aorta low, as also the level of LDL cholesterol in rats fed on cholesterol diet.

An anti-ulcerogenic acylsterylgly- coside, sitoindoside IV, has been isolated from unripe banana.

A pectin containing hexoses (32.4%) and uronic acid (52.5%) has been isolated from the pith of the stem. The pectin was found to exhibit significant hypolipidaemic and hypoglycaemic activity in rats.

The flower extract exhibited hypo- glycaemic activity in rabbits.

The pseudostem is reported to possess lithotriptic and antilithic properties. The extract reduced the precursor of oxalate formation, the liver glycolic acid content in hyperoxaluric rats.

The benzene extract of the root exhibited significant antibacterial and an- tifungal activity.

Protein

The term applies to members of a group of non-crystallisable nitrogenous substances widely distributed in the animal and vegetable kingdoms, and forming the characteristic materials of their tissues and ?uids. They are essentially combinations of AMINO ACIDS. They mostly dissolve in water and are coagulated by heat and various chemical substances. Typical examples of protein substances are white of egg and gelatin.

Proteins constitute an essential part of the diet as a source of energy, and for the replacement of protein lost in the wear and tear of daily life. Their essential constituent from this point of view is the nitrogen which they contain. To be absorbed, or digested, proteins have to be broken down into their constituent amino acids. The adult human body can maintain nitrogenous equilibrium on a mixture of eight amino acids, which are therefore known as the essential (or indispensable) amino acids. They are isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. In addition, infants require histidine.... protein

Nicotinic Acid

(niacin) a B vitamin. Nicotinic acid is a derivative of pyridine and is interchangeable with its amide, nicotinamide. Both forms of the vitamin are equally active. Nicotinamide is a component of the coenzymes *NAD (nicotinamide adenine dinucleotide) and NADP, its phosphate. Nicotinic acid is required in the diet, but can also be synthesized from the essential amino acid tryptophan. A deficiency of the vitamin leads to *pellagra. Good sources of nicotinic acid are meat, yeast extracts, and pulses. The adult RNI (see Dietary Reference Values) depends on the kcal content of the diet and is 6.6 mg niacin equivalent/1000 kcal, which equates to about 17 mg/day for males and 13 mg/day for females. 1 mg niacin equivalent is equal to 1 mg of available nicotinic acid or 60 mg tryptophan.... nicotinic acid

Withania Ashwagandha

Kaul (cultivated var.)

W somnífera (Linn.) Dunal (Chemo- type I, II, III: Israele.) Family: Solanaceae.

Habitat: Throughout the drier and subtropical parts of India.

English: Winter Cherry. (Physalis alkekengi is also known as Winter Cherry.)

Ayurvedic: Ashwagandhaa, Haya- gandhaa, Ashwakanda, Gandharva- gandhaa, Turaga, Turagagandhaa, Turangagandhaa, Vaajigandhaa, Gokarnaa, Vrishaa, Varaahakarni, Varadaa, Balyaa, Vaajikari. (A substitute for Kaakoli and Kshira- kaakoli.) Cultivated var.: Asgandh Naagori. (Indian botanists consider the cultivated plants distinct from the wild ones.)

Unani: Asgandh.

Siddha: Amukkuramkizhangu.

Action: Root—used as an antiinflammatory drug for swellings, tumours, scrofula and rheumatism; and as a sedative and hypnotic in anxiety neurosis. Leaf— anti-inflammatory, hepatopro- tective, antibacterial. Fruits and seeds—diuretic. Withanine— sedative, hypnotic. Withaferin A—major component of biologically active steroids; as effective as hydrocortisone dose for dose. Antibacterial, antitumour, an- tiarthritic, significantly protective against hepatotoxicity in rats.

The root contains several alkaloids, including withanine, withananine, withananinine, pseudo-withanine, somnine, somniferine, somniferinine. The leaves of Indian chemotype contain 12 withanolides, including withaferin A. Steroidal lactones ofwithano- lide series have been isolated.

Withanine is sedative and hypnotic. Withaferin A is antitumour, an- tiarthritic and antibacterial. Anti-inflammatory activity has been attributed to biologically active steroids, of which withaferin A is a major component. The activity is comparable to that of hydrocortisone sodium succinate.

Withaferin A also showed significantly protective effect against CCl4- induced hepatotoxicity in rats. It was as effective as hydrocortisone dose for dose.

The root extract contains an ingredient which has GABA mimetic activity

The free amino acids present in the root include aspartic acid, glycine, tyrosine, alanine, proline, tryptophan, glutamic acid and cystine.

The Ayurvedic Pharmacopoeia ofIn- dia recommends Ashwagandha in im- potency. This claim could not be sustained in a recent experiment and raises a doubt about the equation of classical Ashwagandha with Withania somnifera. A methanolic extract of With- ania somnifera root induced a marked impairment in libido, sexual performance, sexual vigour and penile dysfunction in male rats. (Llayperuma et al, Asian J Androl, 2002, 295-298.)

The total alkaloids of the root exhibited prolonged hypotensive, brady- cardiac and depressant action of the higher cerebral centres in several experimental animals.

A withanolide-free aqueous fraction isolated from the roots of Withania somnifera exhibited antistress activity in a dose-dependent manner in mice. (Phytother Res 2003, 531-6.)

Dosage: Root—3-6 g powder. (API, Vol. I.)... withania ashwagandha

Vitamin B Complex

A group of watersoluble vitamins comprising thiamine (vitamin B1), riboflavin (vitamin B2), niacin, pantothenic acid, pyridoxine (vitamin B6), biotin (vitamin H), and folic acid. Vitamin B12 is discussed above.

Thiamine plays a role in the activities of various enzymes involved in the utilization of carbohydrates and thus in the functioning of nerves, muscles, and the heart. Sources include whole-grain cereals, wholemeal breads, brown rice, pasta, liver, kidney, pork, fish, beans, nuts, and eggs.

Those susceptible to deficiency include elderly people on a poor diet, and people who have hyperthyroidism, malabsorption, or severe alcohol dependence. Deficiency may also occur as a result of severe illness, surgery, or injury.

Mild deficiency may cause tiredness, irritability, and loss of appetite. Severe deficiency may cause abdominal pain, constipation, depression, memory impairment, and beriberi; in alcoholics, it may cause Wernicke–Korsakoff syndrome. Excessive intake is not known to cause harmful effects.

Riboflavin is necessary for the activities of various enzymes involved in the breakdown and utilization of carbohydrates, fats, and proteins; the production of energy in cells; the utilization of other B vitamins; and hormone production by the adrenal glands. Liver, whole grains, milk, eggs, and brewer’s yeast are good sources. People who are susceptible to riboflavin deficiency include those taking phenothiazine antipsychotic drugs, tricyclic antidepressant drugs, or oestrogen-containing oral contraceptives, and those with malabsorption or severe alcohol dependence. Riboflavin deficiency may also occur as a result of serious illness, surgery, or injury.

Prolonged deficiency may cause soreness of the tongue and the corners of the mouth, and eye disorders such as amblyopia and photophobia.

Excessive intake of riboflavin is not known to have any harmful effects.

Niacin plays an essential role in the activities of various enzymes involved in the metabolism of carbohydrates and fats, the functioning of the nervous and digestive systems, the manufacture of sex hormones, and the maintenance of healthy skin. The main dietary sources are liver, lean meat, fish, nuts, and dried beans. Niacin can be made in the body from tryptophan (an amino acid). Most cases of deficiency are due to malabsorption disorders or to severe alcohol dependence. Prolonged niacin deficiency causes pellagra. Excessive intake is not known to cause harmful effects.

Pantothenic acid is essential for the activities of various enzymes involved in the metabolism of carbohydrates and fats, the manufacture of corticosteroids and sex hormones, the utilization of other vitamins, the functioning of the nervous system and adrenal glands, and growth and development. It is present in almost all vegetables, cereals, and animal foods. Deficiency of pantothenic acid usually occurs as a result of malabsorption or alcoholism, but may also occur after severe illness, surgery, or injury. The effects include fatigue, headache, nausea, abdominal pain, numbness and tingling, muscle cramps, and susceptibility to respiratory infections. In severe cases, a peptic ulcer may develop. Excessive intake has no known harmful effects.Pyridoxine aids the activities of various enzymes and hormones involved in the utilization of carbohydrates, fats, and proteins, in the manufacture of red blood cells and antibodies, in the functioning of the digestive and nervous systems, and in the maintenance of healthy skin. Dietary sources are liver, chicken, pork, fish, whole grains, wheatgerm, bananas, potatoes, and dried beans. Pyridoxine is also manufactured by intestinal bacteria. People who are susceptible to pyridoxine deficiency include elderly people who have a poor diet, those with malabsorption or severe alcohol dependence, or those who are taking certain drugs (including penicillamine and isoniazid). Deficiency may cause weakness, irritability, depression, skin disorders, inflammation of the mouth and tongue, anaemia, and, in infants, seizures. In very large amounts, pyridoxine may cause neuritis.

Biotin is essential for the activities of various enzymes involved in the breakdown of fatty acids and carbohydrates and for the excretion of the waste products of protein breakdown. It is present in many foods, especially liver, peanuts, dried beans, egg yolk, mushrooms, bananas, grapefruit, and watermelon. Biotin is also manufactured by bacteria in the intestines. Deficiency may occur during prolonged treatment with antibiotics or sulphonamide drugs. Symptoms are weakness, tiredness, poor appetite, hair loss, depression, inflammation of the tongue, and eczema. Excessive intake has no known harmful effects.

Folic acid is vital for various enzymes involved in the manufacture of nucleic acids and consequently for growth and reproduction, the production of red blood cells, and the functioning of the nervous system. Sources include green vegetables, mushrooms, liver, nuts, dried beans, peas, egg yolk, and wholemeal bread. Mild deficiency is common, but can usually be corrected by increasing dietary intake. More severe deficiency may occur during pregnancy or breastfeeding, in premature or low-birthweight infants, in people undergoing dialysis, in people with certain blood disorders, psoriasis, malabsorption, or alcohol dependence, and in people taking certain drugs. The main effects include anaemia, sores around the mouth, and, in children, poor growth. Folic acid supplements taken just before conception, and for the first 12 weeks of pregnancy, have been shown to reduce the risk of a neural tube defect.... vitamin b complex
