Facts About Whey, Soy, Egg and Casein Protein
Filed under best weight loss programJul 8Protein is a nutrient which is essential to the human body, particularly for the muscle tissues. Nutritionists recommend a daily intake of about .3 grams of protein for every pound of body weight. Bodybuilders and other athletes, however require more protein in their diets to encourage muscle growth and to nourish their bodies to handle the demands of their workouts. These people should get about 1.25 grams/day of protein for each pound of body weight.
The total amount of protein intake is important, but equally important are the sources of dietary protein. Most people are able to get enough protein from their diet; but many athletes require protein supplements to meet their daily requirements for this nutrient. Protein supplements are usually made from four different sources. Each of these protein sources is different and athletes should choose according to their needs.
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 protein 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 of protein.
Soy protein comes from soy flour. It is the most complete vegetable protein. It comes in concentrate and isolate and like whey, the isolate form is higher in protein content and more expensive. Soy protein is easy to digest and the perfect option for people who have milk allergies or are lactose intolerant. However, people with soy allergies can not tolerate soy protein. Soy protein can be added easily to food to increase the nutritional value and can help to lower cholesterol.
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 also a milk protein. Digested at a slower rate than whey, casein protein is often used in combination with other proteins which are more quickly available to the body for sustained nourishment. Casein protein is a good choice for meals prior to workouts and for taking before bed. Like whey protein, casein protein should be avoided by the lactose intolerant and those with milk allergies.
Choosing the right protein is about choosing what your body will tolerate the best and what protein will work for your exercise habits the best. You should consider all pros and cons of each type before you make your final decision about protein supplements.
