2. 2 + PROTEIN Protein is essential to good health. The very origin of the word — from the Greek  protos , meaning “first” — reflects protein’s top-shelf status in human nutrition. You need it to put meat on your bones and to make hair, blood, connective tissue, antibodies, enzymes, and more. It’s common for athletes and bodybuilders to wolf down extra protein to bulk up. But the message the rest of us often get is that we’re eating too much protein. Add a Footer 2

3.  The RDA, the estimated amount of a nutrient (or calories) per day considered necessary for the maintenance of good health by the Food and  Nutrition  Board of the National Research Council/ National Academy of Sciences. The RDA is updated periodically to reflect new knowledge. It is popularly called the Recommended Daily Allowance. Recommended Dietary Allowance: 3

4. 2 + Protein RDA   Protein recommendations are mainly based on the individuals body weight. The protein RDA is high, to cover most person’s needs. The average requirement  for protein is 0.6 grams per kilogram of body weight; the RDA is 0.8 grams this is said to meet 97.5% of the population’s needs. Add a Footer 4

5. The Recommended Dietary Allowance (RDA) for protein is a modest 0.8 grams of protein per kilogram of body weight. The RDA is the amount of a nutrient you need to meet your basic nutritional requirements. In a sense, it’s the minimum amount you need to keep from getting sick — not the specific amount you are supposed to eat every day. To determine your RDA for protein, you can multiply your weight in pounds by 0.36 , or  use this online protein calculator . DAILY REQUIRMENTS 5

6. 2 + For example For a 50-year-old woman who weights 140 pounds woman and who is sedentary (doesn’t  exercise ), that translates into 53 grams of protein a day.   Add a Footer 6

7. But use of the RDA to determine how much protein you need daily has actually caused a lot of confusion. “There’s a misunderstanding not only among the public, but also somewhat in our profession about the RDA,” says Nancy Rodriguez “People in general think we all eat too much protein.” LOT OF CONFUSION 7

10. 2 + AJCA Rodriguez was among more than 40 nutrition scientists who gathered in Washington, D.C., for a “Protein Summit” to discuss research on protein and human health. The summit was organized and sponsored by beef, egg, and other animal-based food industry groups, but it also generated a set of scientific reports that were independently published a  special supplement to the June issue of the  American   Journal of Clinical Nutrition  (AJCN).

11. For a relatively active adult, eating enough protein to meet the RDA would supply as little as 10% of his or her total daily calories. Beef, poultry, and pork (as well as milk, cheese, and eggs) can certainly provide high-quality protein, but so can many plant foods — including whole grains, beans and other legumes, nuts, and vegetables. 11
