Protein not just the bodybuilder

1. Animal protein (with the exception of gelatin) provides all nine essential amino acids in the proportions required by the body and is therefore referred to as complete, or high-quality, protein.
2. Plant Protein In contrast, plant proteins (with the exception of soy) lack one or more of the essential amino acids.
3. DNA (deoxyribonucleic acid), the genetic material that is found in the nucleus of each body cell, provides the blueprint for how amino acids are arranged to form individual proteins.
4. Keratin, still another type of protein, is used by the body to make hair and nails.
5. Connective tissue made from protein forms the matrix of bones.
6. Just as the letters in the alphabet are joined to make words, so too are amino acids arranged in an almost infinite number of different ways to form the more than 50,000 different proteins in the body.(proteomics,is the  study of  protein structure in detail)
7. The human body requires 20 different amino acids to build all the proteins it needs.
8. With the exception of oils and pure sugar, all foods contain at least some protein, but its quality varies according to the amino acids it provides.
9. Animal Protein Proteins are made of amino acids.Of these, 11 can be made in the body, but the other nine referred to as essential amino acids, must come from the diet.
10. How Proteins Harm and Heal Protein is the quintessential nutrient that every cell in the human body requires for growth or repair.
11. By combining a grain with a legume, you can obtain the complete range of amino acids.
12. Interestingly, many cuisines include classic combinations that do just that. For example, Refried beans and corn tortillas of Mexico • Rice and dahl of India • Tofu, rice, and vegetable combinations in Asian cuisine • Chickpeas and bulgur wheat in Middle Eastern dishes 
13. They simply need to make sure that they eat foods with the right combination of amino acids.
14. This essential amino acid is plentiful in dried beans and other legumes, which are deficient in methionine.
15. For example, grains are high in the essential amino acid methionine, but they lack lysine.
16. With so many essential functions linked to the protein, you might assume that it should make up the bulk of your diet, but this is not the case.
17. Healthy adults only need 0.36 g per lb (0.8 g per kg) of body weight of protein every day, though if you exercise regularly, you may need more.
18. Thus, a person weighing 154 lbs (70 kg) requires 56 g of protein per day—the amount in a 3-oz serving of chicken.
