Macronutrients are nutrients the body needs in large amounts, because they provide the body with energy. Carbohydrates
Proteins
Most adults in the US get more than enough protein to meet their needs. It's rare for someone who is healthy and eating a varied diet to not get enough protein. Emphasize plant sources of protein, such as beans, lentils, soy products and unsalted nuts. Include seafood twice a week. Meat, poultry and dairy products should be lean or low fat. Fats
Micronutrients: Vitamins and MineralsWater-Soluble VitaminsWater-soluble vitamins travel freely through the body and excess amounts are usually excreted by the kidneys. The body needs water-soluble vitamins in frequent, small doses. These vitamins are not as likely as fat-soluble vitamins to reach toxic levels.
Fat-soluble vitaminsFat-soluble vitamins are stored in the body's cells and are not excreted as easily as water-soluble vitamins. They do not need to be consumed as often as water-soluble vitamins, although adequate amounts are needed. Too much of a fat-soluble vitamin can become toxic. A balanced diet usually provides enough fat-soluble vitamins.
