Types of Vitamins:
Fat soluble Vitamin 'A' or Anti-Opthalmic vitamin seem to occur mostly in cod-liver oil, milk, dairy products, fruits and leafy vegetables. Lack of Vitamin A results in lowered resistance to eye infections lack of full growth, sediment and stones in kidney and bladder.
Water soluble Vitamin 'B' is contained principally in yeast, whole grain, milk, fruits, and vegetables.
Lately it has been found that Vitamin 'B' consisted of more than one factor; one factor which was affected by heat, and
another one which, withstood heating. As designation of these two factors 'F' (Bl) and 'G' (B2) has been suggested. 'F' for antineuritic, and 'G' for the factor which has been found to prevent pellagra. Lack of vitamin (B) (Bl) results in polyneuritis (Inflammation of the nerves) general bodily emaciation, loss of appetite and fatigue.
Water soluble Vitamin 'C' or Anti-scorbutic vitamin is sup posed to be present in large amounts in fresh fruits (especially oranges, grapefruits, lemon, and limes). Vegetables and sprouting grains. Lack of Vitamin C results in bleeding and ulcerated gums, scurvy, tooth decay, loss of weight.
soluble Vitamin 'D' controls them metabolism of calcium and phosphorus in bone-building and teeth formation. It can be had from cod-liver oil, milk, egg-yolk, and sunshine.
The amount of Vitamin 'D' in foods can be increased by exposing them to Ultra Rays, a process is called "irradiation" Lack of Vitamin D results in rickets, bending and softening of the bones, deformities, failure of calcium metabolism.
Fat soluble Vitamin E also called anti-sterility vitamin, was originally referred to as Vitamin X because of the uncertainty, due to lack of knowledge about it as to whether or not it should be classed as a vitamin.
The richest source yet found of Vitamin E is the germ of the wheat kernel. It is also found in lettuce, watercress, beans. Lack of Vitamin E results in loss of reproductive powers, disturbance during pregnancy, death of the foetus or embryo.
