What is the mechanism or cause of the anemia associated with vitamin E deficiency?

Hemolytic anemia is a type of anemia that causes red blood cells to become fragile and die prematurely. Because vitamin E protects the red blood cell membrane from oxidative damage, deficiency can cause hemolytic anemia.

Why is vitamin Da a nutrient that the elderly should be concerned about?

What are the physiological changes that occurs with aging that have an impact on nutrition?

Physiologic factors affecting intake control during childhood and adolescence include age, sex, pubertal stage, body fatness, and the macronutrient composition of food .

What are some of the physiological changes that occur in the bodys systems with aging?

Physiological changes occur with aging in all organ systems. The cardiac output decreases, blood pressure increases and arteriosclerosis develops. The lungs show impaired gas exchange, a decrease in vital capacity and slower expiratory flow rates.
