Choosing Protein Supplements: The Four Important Protein Sources
Protein 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.
Not only is the amount of protein important, but the source of the protein also matters. For the average person, diet alone is sufficient to get the needed amount of protein, but for those who need more than the average amount of protein, there are protein supplements that are necessary. There are 4 different types of protein that can be used. Each reacts differently and so the type of protein used should be chosen carefully.
The 4 common types of protein supplements are whey, soy, egg and casein. Protein supplements can be strictly one type of protein or it can be a mix of, usually, two different types of protein.
Whey protein is derived from milk and is the protein source used in the majority of protein supplements. Whey protein contains both essential and nonessential amino acids. The essential amino acids are those which must be obtained through the diet since our bodies cannot produce them " and as you may have guessed, nonessential amino acids are those which we can produce, but may want more of through dietary sources. Whey protein is easily digested and used by the human body, the exception being those who have allergies to milk, who should avoid concentrated whey protein. As it happens, the concentrated form is preferred for protein supplements, being inexpensive to produce and containing between 30% and 85% protein by weight. There are also whey protein isolates, with a protein content of around 90%, which are more expensive. Whey protein is not only an excellent protein source, but also boosts immune function, contains amino acids and is helpful in speeding along muscle recovery after a workout.
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 is often mentioned as being the best protein supplements. This protein comes from egg whites and is quickly and completely digestible. Containing all of the essential amino acids, it's also a popular ingredient in protein supplements. However, there are those who are allergic to eggs and should not use protein supplements containing egg protein.
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.
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. - 17268
