Proteins are contained in meat, fish, dairy products, and legumes, which are peas and beans. Carbohydrates are the body's main source of energy. They are found in fruits, grains, vegetables and sugars. Carbohydrates are stored in the body as glycogen, a quick source of energy. If eaten in excess or unused due to lack of exercise the body changes them into fat for storage.
Fats help to move vitamins to various parts of the body and help in cell and hormone production.
Fats are found in oils, many dairy products, meats, nuts and seeds. Some people may need to take vitamins or mineral tablets to supplement their diets. In addition, you should drink plenty of water. Water is often called the forgotten nutrient because it is common not to drink enough of it. Water replaces moisture lost in urine and sweat.
