Read the following passage and answer the questions below:

While eating food, we should bear in mind that we do not eat just to satisfy our hunger or to fill the belly. We eat to preserve our health. For good health, we need good food. Sometimes it so happens that people who live even in the midst of plenty do not eat foods they need for good health because they have no knowledge of the science of health and nutrition. They do not know how to select balance diet from many foods that are available to them. One of the main reasons of malnutrition in Bangladesh is our ignorance of the knowledge of nutrition. Again, the poor and illiterate people in our country generally think that good and nutritive food means a costly food. They do not know that whatever food they get could be good and nutritive if they could select the food items wisely to make it a balance one.
