Why Vitamins are essential for our diet?

Vitamins are an essential substance that must be present in the diet in small quantities & whose deficiency causes deficiency disease. Vitamins are a group of compounds required in small quantities for controlling metabolism and body function.

As we all know, A.I. Lumin discovered Vitamin. Funk gave the term vitamin. Funk (1911) isolate concentrate from rice polishing, which contains nitrogenous bases (Ameenes). Vitamins are not synthesized in the body (except vitamin D & vitamin K). Vitamins are divided into two parts-

FAT SOLUBLE [ Vitamin A, Vit. D, Vit. E, Vit K ]

Soluble in fat. They can be easily stored in the body( liver)

WATER SOLUBLE [ Vitamin B complex and Vitamin C]

Soluble in water doesn't retain in body.

Fish liver oil, Dairy products, Green vegetables, and carrots contain carotene that can be converted into retinol.	Night blindness, Nyctalopia, Xerepadania [Drycornia]
VITAMIN D (CALCIFEROL/ Sunshine Vit.)	Promote absorption of calcium and phosphorus from the intestine. Necessary for formation of normal bones.	Fish, Egg Yolk, Milk, etc	Rickets in children ( soft bones that bend easily) Osteomalacia in adults (joints pain)
VITAMIN E (Tocopherol/beauty vitamin/ Antisterlity factor)	Formation of RBCs. Maintain healthy skin and cholesterol levels and also functions as an antioxidant.	Vegetable oil, serial products, Nuts, egg, etc	Mild anemia sterility/ Infertility.
VITAMIN K (PHYLLOQUINONE)	Help information of prothrombin (Involve in blood clotting) Besides this, intestinal bacteria also synthesized Vitamin K.	Green leafy vegetables( Spinach, Cabbage, etc.)	Delayed blood clotting.
