Proteins are the building blocks of the body.
Made up of amino acids, they are used to create, maintain,
and repair all the protein components of the body, like skin,
hair, bones, organs, muscles plus enzymes, hormones and even
also supplies energy - but not as readily as carbohydrates.
best sources of protein are animal foods, especially lean
meats, fish, tuna, eggs and cottage cheese. Beans, lentils
and nuts are other good sources. Other acceptable protein
sources are Whey protein isolate and concentrate and Soy protein
isolate. Be aware that not all proteins are nutritionally
the same. Deli meats, hard cheeses, fatty meats like duck
and ham, processed meats (hot dogs, sausages etc) are all
poor choices. They contain too much fat and does not provide
the body with the correct amino acid balance.
carbohydrate, protein contains 4 calories per gram.
protein from beans and lentils is generally healthier because
it is lower in fat.
