Malnutrition is a condition that results from eating a diet in which one or more nutrients are either not enough or are too much such that the diet causes health problems. It may involve calories, protein, carbohydrates, fat, vitamins or minerals.Malnutrition is not just about food, or just about health care, but is an issue that requires action from different angles. Malnutrition reduces the growth of the baby and increases chances of it having a low birth weight, and later suffering from childhood infections and mortality.
