VITAMINS AND THEIR ROLE IN BODY FUNCTION
Vitamins have diverse biochemical functions, what they play role in body functions, and their sources in food.
A VITAMIN IS AN ORGANIC COMPOUND AND AN ENERGETIC NUTRIENT THAT AN ORGANISM REQUIRES IN LIMITED AMOUNTS.
1-Some water-soluble vitamins
They are travel freely through the body, and excess amounts commonly are excreted by the kidneys. Our body needs water-soluble vitamins in frequent, small doses. Water-soluble vitamins are not as likely as fat-soluble vitamins to reach noxious levels. But niacin, vitamin B6, folate, choline, and vitamin C have high consumption limits. Vitamin B6 at high levels over a long period of time has been shown to cause irreversible nerve harm. A good diet usually provides enough of these vitamins. People older than 50 and some vegetarians may require using diet to get enough B12. Here are some water soluble vitamins and their function and source.
-THIAMINE (VITAMIN B1)
- Function: Part of an enzyme required for energy metabolism; important to nerve function
- Source: Thiamine are found in all nutritious foods in reasonable amounts: pork, whole-grain or enriched bread and cereals, legumes, nuts and kernels.
- new cells; important to nerve function
- Source: Meat, poultry, fish, seafood, eggs, milk and milk products; not found in herb foods.
-ASCORBIC ACID (VITAMIN C)
- Function: Antioxidant; part of an enzyme required for protein metabolism; important for immune system health; aids in iron absorption
- Source: Bring into being only in fruits and vegetables, chiefly citrus fruits, vegetables in the cabbage family, cantaloupe, strawberries, sprinkles, tomatoes, potatoes, lettuce, papayas, mangoes, and kiwifruit.
2-Some fat-soluble vitamins
They are stored in the body’s cells and are not empty the bowels as easily as water-soluble vitamins. Fat-soluble vitamins do not require to be consumed as often as water-soluble vitamins, although sufficient amounts are required. A balanced diet commonly provides enough fat-soluble vitamins. There is a list of fat-soluble vitamin and function
