We eat to live but,while eating food,we don't think that we eat to preserve our health too.We should bear in mind that we do not eat just to satisfy hunger or to fill the belly. We eat to lead a healthy and happy life.For good health we need good food.The poor and illiterate people tn our country generally think that food food means a costly food.But they do not think whatever food they get could be food and nutritive if they could select the food items properly to make it a balanced diet.Sometimes it so happens that people who live even in plenty do not eat the foods they need for good health, because they have no knowledge of the science of health and nutrition.One of the main reasons of malnutrition is our lack of knowledge of nutrition.
