Nutrition is the science of food and its relationship to health. Food plays an important role in health as well as in disease.1 With the current increase in lifestyle disorders around the world, it is important to promote healthy nutrition in all age groups. Improving eating habits is not just for an individual but for the whole population. Nutrition is double edged sword as both over and under nutrition is harmful to health. Under nutrition is particularly harmful in early age groups i.e. childhood and over nutrition in adulthood and after-years but both forms are likely to affect all age groups in near future. Some important diseases like malnutrition are obesity caused by excess energy intake, anemia caused by insufficient intake of iron, thyroid deficiency disorders due to deficiency in iodine intake and impaired vision because of inadequate intake of vitamin A etc.
