The Foundation Of Protein Supplements: Protein Sources
Protein is one of the essential nutrients our bodies need. Our muscles especially require it for maintenance and growth. For most people, around .3 grams per pound of body weight is the recommended daily intake. However, athletes in general and bodybuilders in particular need far more; around 1.25 grams per pound each day. These people need more protein to build muscle and fuel their bodies for their exercise regimens.
It's not only how much protein you get though; it's also where it comes from that matters. While most of us get all the protein we need from our diets, athletes often need supplements to provide them with enough of this important nutrient. The protein used in protein supplements is nearly always from the same four sources. Each is used differently by the body and are more or less suitable for different individuals.
These four sources used in most protein supplements are egg, whey, soy and casein. There are protein supplements which use only one type, but it is more common to have two of these proteins in a single supplement.
Whey protein comes from milk and is the most common of these four sources used to produce protein supplements. This protein contains essential amino acids (those which we cannot produce ourselves and must take in through dietary sources) and nonessential amino acids. Except for people who are allergic to milk or have lactose intolerance (who should avoid whey protein), this is a great source of protein which is readily digested. Concentrated whey contains 30%-85% protein and is inexpensive, making it a common ingredient in protein supplements. Whey protein isolates contain around 90% protein by weight, but are far more costly. Whey protein helps improve immune function and speeds muscle recovery in addition to being a good source.
Soy protein is made from soy flour and is the most complete plant-based protein available. Just as with whey powder, there are soy protein concentrates and isolates, with the isolate being a richer source of protein but also more costly. Soy protein is also easily digestible and is suitable for persons with milk allergies or lactose intolerance. There are however some people who are allergic to soy and obviously, these people should not use soy-based protein supplements. Soy protein can be mixed into foods to increase the protein content and has the added benefit of helping to regulate cholesterol levels.
Egg protein comes from egg whites. It is fat free and very high in protein. It contains all the essential amino acids and is completely absorbed by the body. It is considered the best protein source. It should not be used by people who have egg allergies.
Casein is another protein derived from milk. Casein protein is digested more slowly than whey, which makes it a protein often combined with other, more quickly digester proteins. Casein protein is ideal for adding to pre-workout meals or before bed. As with whey protein, those with milk allergies should avoid casein protein.
When you're shopping for protein supplements, always read the label to make sure that the protein sources used are suitable for your needs and that you can safely ingest. Protein supplements can be a great thing " but make sure you choose well. - 17269
