Why do we need food?

We need food for energy, growth, and maintaining the proper functioning of our body systems. Food provides the necessary nutrients and energy our bodies need to perform various functions. It supplies carbohydrates, proteins, fats, vitamins, and minerals that are essential for bodily functions like cell repair, muscle growth, and brain function. 

Without adequate food, our bodies would not be able to produce the energy required for daily activities, and our systems would not function optimally. Food also helps to maintain the balance of bodily fluids, regulate body temperature, and support immune functions.
