The human body needs macro nutrients – proteins, carbohydrates and fats for nutrition. In addition it needs various micro nutrients and Vitamins. Vitamins play a critical role in how our body functions. However, the body cannot produce all the Vitamins and Minerals required by the body and requires it from external sources. Vitamins can be broadly classified into two categories, fat soluble and water soluble.
Fat soluble Vitamins are found in fatty foods and animal products such as milk, dairy foods, eggs, liver and butter. Fat soluble Vitamins are Vitamin A,D,E & K. Your body is capable of absorbing and storing fat soluble Vitamins and therefore if your diet includes some of these sources of Vitamins, you dont need to eat it everyday. Fat soluble Vitamins are necessary for bone growth, uptake of calcium and phosphate, development of your immunity, as antioxidants and for the clotting of your blood.
Water soluble Vitamins are not stored in the body and therefore need to be ingested regularly. Since the body does not store these Vitamins, they are generally not harmful (obviously up to a point) even if consumed in large quantities. Water soluble Vitamins are B, C and folic acid and are found in fruits, vegetables, grains, milk and dairy. They can be destroyed by heat and therefore heating the source of these Vitamins can result in a loss of these Vitamins. Water soluble Vitams are necessary for boosting immunity, absorbtion of iron, processing carbohydrates, cholestrol, proteins production of energy, production of new cells, division of cells, production of red blood cells, proper functioning of nerves and the maintenance of bones, nerves and sweat glands.
Many nutritionists suggest taking a multi-vitamin tablet to ensure that you get adequate Vitamins daily.
