Q: What role do proteins and carbohydrates play in the diet? Answer from Kimra Hawk, R. Each of these nutrients plays a unique role in building and maintaining a healthy body, so any diet that deprives you of one or the other over an extended period of time can put your health at risk. Protein is the raw material your body uses to make and maintain healthy muscles, bones, skin and hair. Without an ongoing supply of this nutrient you would gradually lose muscle mass, become weak and forfeit your ability to fight disease and infection. The average adult needs about 60 to 80 grams of protein each day. That may sound like a lot, but not when you consider threes ounces of meat about the size of a deck of cards provides 21 grams of protein. The best sources of protein include meat, fish, eggs, milk, cheese and legumes beans, peanuts, peas and soybean-derived foods. Some vegetables and grains contain protein, though not of the same quality as the primary sources I mentioned. Your brain, heart and kidneys depend on carbohydrates for energy to function properly. If your diet does not include enough carbohydrates your body will take extreme measures to get the energy it needs; it will feed on carbohydrates stored in muscles and attempt to chemically break down the proteins you eat until those proteins look and act like carbohydrates.

Three nutrients — carbohydrate, protein, and fat — contain calories that your body uses for energy. Here’s how to balance these nutrients in a healthy diet. Carbohydrate has 4 calories per gram. About 50 to 60 percent of your total daily calories should come from carbohydrate. Carbohydrate contains the most glucose and gives the quickest form of energy. Your body changes percent of carbohydrate into glucose. Besides giving your body energy that it uses right away, your body can store carbohydrate in your liver. Your liver stores extra carbohydrate as glycogen and releases it later, when your body needs it. However, there’s a limit to the amount of glycogen your liver can store. Once your liver has reached that limit, your body turns the extra carbohydrate into fat.
