What is protein?



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 genes.

Protein also supplies energy - but not as readily as carbohydrates.

The 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.

Like carbohydrate, protein contains 4 calories per gram.

Plant protein from beans and lentils is generally healthier because it is lower in fat.
