Define Importance of Nutrition in Human Body?

Nutrition is increasingly being recognized as an important determinant, which modulates the biological process of ageing. Poor nutrient intakes and suboptimal diets have been implicated for many of the biological changes and increased risks for chronic diseases rather than the ageing process per se. Many of the chronic degenerative diseases of older persons such as cardiovascular disease, diabetes, obesity, osteoporosis and anaemias due to iron, folic acid and vitamin Bj2 deficiency have preventable causes, including nutritional causes. Enhanced dietary intakes and more physically active life styles can help to prevent or control these conditions.
