ABC of VITAMINS

The human body is like a power engine. Just as a machine needs to be fuelled constantly, our body must be replenished regularly with vitamins for it to function properly. Vitamins, which function as catalysts and coenzymes, protect cells and are important links in the metabolic armour.





Each of the vitamins - A, C, D, E, K and B (B1, B2, B3, B5, B6, B9 and B12) - has an individual role to play in the body. Barring vitamins B12 and D3, vitamins A, B, C, and E are dietary. 




Vitamin A (Retinol/Beta carotene) 
It's needed for healthy eyes and bone development. It also helps in healing infections as it strengthens the immune system and enhances the production of RNA (Ribonucleicacid).
Found in : Cod liver oil, egg, yellow fruits and vegetables. Carotene rich foods like spirulina, wheat grass, sweet potato, carrots, green onion, spinach, Chinese cabbage, melons, peaches, yellow peppers and mango.

Vitamin B1 (Thiamine) 
It helps in converting glucose into energy.
Found in: Brown rice, millet, wheat germ, nuts, wheat bran and sprouted grains.

Vitamin B2 (Riboflavin) 
It helps in the conversion of fats, sugar, proteins into energy and the formation of red blood cells.
Found in: Milk products, yeast extract, organ meats, eggs, mushrooms and asparagus.

Vitamin B3 (Niacin) 
Your cells breathe because of vitamin B3. It promotes healthy skin and maintains blood sugar levels.
Found in: Whole grains, legumes, fish, chicken, turkey as well as mushrooms.

Vitamin B5 (Pantothenic acid) 
This helps in the production of anti-stress hormones. It also promotes healthy skin, hair and nerves.
Found in: Egg, chicken, mutton, fish and vegetables such as mushrooms, avocados, wholewheat, lentils and sunflower seeds.

Vitamin B6 
Vitamin B6 is considered to be an anti-depressant. It's also involved in blood formation, is fundamental for protein metabolism and nervous system function.
Found in: Meat, salmon, banana, broccoli, red kidney beans, asparagus, cauliflower, cabbage and all green leafy vegetables.

Vitamin B9 (Folic acid) 
This vitamin is important for pregnant women as it helps the synthesis of DNA and protein. It is also essential for red blood cell formation.
Found in: Whole grains, chicken, liver, spinach, red kidney beans, raspberry, beet root, asparagus, cashews, peanuts, chick peas, avocado, wheat germ, and tomato juice.

Vitamin B12 
Helps maintain healthy nervous system, required for normal growth and production of red blood cells. It also helps break down fatty acids. Vitamin B12 is manufactured only in the colon, that too in inadequate quantities.
Found in: It is not a problem for meat eaters. Unfortunately, the only source for vegetarians is the faecal content in water and that doesn't help. Some fermented food like quick pickles, soya, tofu and spirulina have B12.

Vitamin C 
This aids in tissue healing, formation of bones and teeth. It is also a rich anti-oxidant.
Found in: Fruits and vegetables like guava, lemons, papaya, strawberry, melon, grapes, sprouted seeds, beans, broccoli, bell peppers, oranges, parsley and cauliflower.

Vitamin D3 
This is essential for metabolism, skeletal formation and teeth. It promotes the absorption of calcium. Yet only 10-15 per cent of the vitamin content comes from a balanced diet. The rest is derived from sunlight, which is absorbed through the skin.
Found in: Sunlight. Longhours in air-conditioned spaces and pollution make it hard. Even sunscreen lotion prevents absorption. We need supplements of Vitamin D3. Consuming fish, sardine, tuna, egg, and green leafy vegetables also helps.

Vitamin E 
A healthy dose of vitamin E detoxifies the liver. It is an antioxidant, protects cells and helps maintain red blood cells.
Found in: Soya beans, broccoli, green leafy vegetables, sunflower seeds, whole grains, nuts, legumes, outer leaves of cabbage, asparagus, cucumbers and sprouted grains.

Vitamin k 
It is important in the blood clotting process.
Found in: The cabbage family - broccoli, green and red cabbage, pack choy flower, cauliflower, turnip, knol khol (ganth gobi), legumes, potatoes, tomatoes, alpha alpha, asparagus and green leafy vegetables.
