Vitamins deficiency

Vitamin deficiencyIf you don't get a particular vitamin for a long time, you develop a vitamin deficiency. If the deficiency goes on long enough, you get a vitamin deficiency disease. The classic example of a deficiency disease is scurvy, caused by a lack of Vitamin C (we'll explain more about this in Chapter 13). Long before you start having any of the signs of a deficiency disease—and long before the deficiency shows up in the usual medical tests—you could be marginally deficient in a vitamin or mineral. Here's very good example: Many older adults are marginally deficient in cobalamin (Vitamin B12). The main symptom of classic cobalamin deficiency is anemia, which a doctor can easily diagnose with a simple blood test. Long before anemia sets in, though, marginal cobalamin deficiency leads to depression, confused thinking, and other mental symptoms that look a lot like senility. Poor diet is playing a bigger role in his mental condition than you might realize.

For example, one of the earliest symptoms of Vitamin A deficiency  is  night blindness and other eye problems. Vitamin A deficiencyalso  causes xerophthalmia. A shortage of Vitamin C weakens the walls of your blood vessels.  It has been shown that the liver loses its ability to inactivate estrogen in vitamin B-complex deficiency. Thiamine deficiency causes beriberi. Niacin deficiency -pellagra. Vitamin B12 shortage leads to megaloblastic anemia. And it is well known fact that vitamin C deficiency leads to scurvy.  It is far not full list of diseases caused shortage of vitamins and minerals.
