What will be an ideal response?
Water is the most important nutrient because it is involved in almost every vital body process: in digesting and absorbing food, in producing energy, in the circulatory process, in regulating body heat and electrolyte balance, in removing waste products, in building and rebuilding cells, in transporting essential nutrients, and in cushioning joints and organs. Water is contained in almost all foods but primarily in liquid foods, fruits, and vegetables. Caffeine-containing drinks are also acceptable as a water source
