This essay defines vitamins and describes their various sources and the effects of their deficiency on the human body.
Vitamins are certain chemical elements necessary for the health and growth of the human body. They are essential ingredients of our food. Their deficiency or absence in the human body causes different diseases and affects the growth of limbs and joints of the body. For example, sailors on the ships of East India Company were attacked by scurvy. They were asked to use lemons and oranges. Beri, a disease that paralyzes legs attacks those living in places with hard conditions as prisons or labor camps. During 1880 it attacked troops of the Japanese navy. Vegetables, fish, meat, and barley were prescribed to them.
Vitamins are named after alphabets based on their solubility in fats or water. Vitamins A, D, and E can be dissolved in fats and are called fat-soluble. Vitamin A can be found in cod liver oil, butter, and green vegetables. Its deficiency affects the growth of young animals and weakens physical resistance and eye-sight: Vitamin D can be had from cod liver oil, animal fats, sunlight, and irradiated vegetable oil. Its deficiency affects the growth and formation of bones and causes rickets Food can be made more effective with the ultra-violet light of the sun. Irradiated cod liver oil is also more effective than an ordinary one. Vitamin E or anti-sterility vitamin is available in leaves, seeds, and common food. Its absence affects the reproductive system. This is why childless couples are given doses of wheat-germ oil.
Vitamins that dissolve in water are B and C and are called water-soluble vitamins. Vitamin B is found in grain and yeast. Its deficiency causes beriberi and pellagra. Research has revealed that it contains six different substances of varying importance. We can get vitamin C from fresh vegetables, peas, beans. It is also found in fruits especially in lemons and oranges. Its deficiency causes scurvy. Hence we can say the presence of all vitamins in suitable quantity is mandatory for the growth and development of the human body.
