What Is ProteinProtein is not the body's energy source of choice, but it can be used for energy when there are not enough carbohydrates and fats in the diet. The protein you consume contributes to the development of muscles, bones, cartilage, skin, antibodies, hormones, and enzymes in your body. It is important in the building and maintaining of all bodily structuresHow Protein is Used in the BodyProtein is built by a combination of chemical structures called (40110 acids. There are about twenty amino acids that the body needs, amt these are often referred to as the building blocks of body. Of the two amino acids, nine are essential to the diet, meaning they must be supplied by the foods we eat. The remaining amino acids can be in the body. When a food is consumed that includes all nine of the essential amino acids, it is referred to as a complete protein source Meat, poultry, fish, eggs, and dairy products like milk and cheese al complete protein sources. Incomplete sources of protein are those t not contain the amount of essential amino acids needed by the body These sources are primarily those fruits and vegetables. But some p sources offer some of the essential amino acids while others offer the remaining ones. By combining various sources of plant proteins with other, a complete protein source can be made. For example, if rice consumed with beans, this combination becomes a complete protein source. These combinations of foods are necessary for vegetarians who do not eat meat sources of protein and may have difficulties in me protein requirements. Your body needs the right balance of all twenty amino acids in order to adequately build tissues in the body. If any one is missing the protein will not be built. Protein RequirementsThe amount of protein needed by a person is based on age, sex and body size. The Recommended Dietary Allowance for protein in adult males over twenty years of age ranges from 58 to 63 grams per day. For adult females over twenty, the allowance ranges from 46 to 50 gram per day. Most people do not have trouble meeting protein requirements. In fact, many often consume more than they need, up to twice as much.Protein and Weight ReductionMany people have been drawn to weight-reduction diets that are high in protein. Individuals have found that these high-protein diets actually lead to weight loss. But excess protein in the diet is not a wise choice. Too much protein (any in many cases too much fat that results as well) can lead to risk of health problems along with a condition called ketosis. This condition develops from not having significant sources of energy (from carbohydrates) that, as a result, makes the body use protein for energy. It can cause extra work for the liver and kidneys and can actually be harmful in the long run. This is one reason that consuming excess protein through high-protein diets is not a healthy way to lose weight. Contribution of Protein to the Overall DietProtein should account for about 15 percent of total daily calories. For a person consuming a 2,000-calorie diet, this would equate to about 300 total calories. A variety of lean meats, poultry, fish, eggs, low-fat dairy products, and dried beans and peas should contribute to this intake. |
