Food is essential for our body for a number of reasons. It gives us the energy needed for working, playing and doing day-to-day activities. It helps us to grow, makes our bones and muscles stronger, repairs damaged body cells and boosts our immunity against external harmful elements like pathogens. Besides, food also gives us a kind of satisfaction that is integral to our mental wellbeing, but there are some foods that are not healthy. Only those food items that contain nutrients in a balanced proportion are generally considered as healthy. People of all ages must be aware of the benefits of eating healthy food because it ensures a reasonably disease-free, fit life for many years.
