As we know,good health is more important than wealth. Food gives us energy,so we must have enough food to keep healthy.we should eat more fruit and vegetables and less meat,and we also must have right kinds of food. A cup of milk a day can help make us healthy as well.Different foods help us in different ways,if we eat too little or too much,or if we choose the wrong food,we may become sick,so we must have meals three times every day on time,too. It's necessary for us to have healthy eating habits.
