There are 13 vitamins, which are categorized under two major types, namely water soluble (four) and fat soluble (nine). The former type includes vitamin A, D, E and K, whereas the latter encompasses vitamin B and subtypes and vitamin C. As the name indicates, water soluble vitamins can be dissolved in water, while fat soluble ones are absorbed by the body using lipids and/or fats. Following is a list of vitamins and the role of vitamins in the body:
Vitamin A: The role of vitamin A is to regulate the tissues and membranes and also to keep the skin, eye, bone and teeth healthy. Vitamin A is present in certain food items such as milk, egg yolk, carrots, leafy vegetables, oranges, lime and pineapple.
Vitamin B: As already mentioned, there are nine types of vitamin B, each of which plays an important function. To mention a few, vitamin B plays a significant role in growth, development, cell division, carbohydrate metabolism and neurological function. Vitamin B rich foods include some vegetables, legumes, fruits, whole grains, nuts, eggs, meat and poultry.
Vitamin C: Vitamin C is responsible for tissue formation and maintenance of the cell membranes. It is present in certain fruits (particularly citrus fruits) and vegetables like oranges, lime, tomatoes, onions, broccoli, peppers and cabbage.
Vitamin D: Human body can synthesize vitamin D on its own by exposing to sunlight. The role of vitamin D is to boost the health of the bones and teeth. Foods that contain vitamin D include milk, egg yolk, salmon and other seafood.
Vitamin E: Vitamin E is essential for hair growth, tissue healing and other metabolic processes. It plays a major role in protecting the tissues of the eyes, skin and liver. Vitamin E is present in nearly all types of fruits and vegetables.
Vitamin K: Vitamin K can also be produced by our body. It is essential for coagulation and/or clotting of blood. Vitamin K rich foods include dairy products, soybean and green leafy vegetables.
