Choosing Protein Supplements: The Four Important Protein Sources
Protein is an essential nutrient for the body, especially for the muscles. The general recommendation is an intake of around .3 grams of protein for each pound a person weighs. For athletes and bodybuilders, though, the requirement is higher because the body is working harder and demands more. The recommendation jumps from .3 to 1.25 grams for this group of people.
Not only is the amount of protein important, but the source also matters. For the average person, diet alone is sufficient to get the needed amount, but for those who need more than the average amount, 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 should be chosen carefully.
The four protein sources common in protein supplements are whey, soy, casein and egg. While some protein supplements are made from just one source, most often there will be protein from two of these sources in a given protein supplement.
Whey protein is derived from milk and is the 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, 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 this type of 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 protein comes from milk, but unlike whey it is slow to digest. It is slow acting and therefore often used in combination with faster acting proteins. It works well meals prior to workouts. It also is a great choice to take just before bed.
Read the labels of those protein supplements to make sure you're purchasing one that you'll tolerate and will give you the protein you need for your exercise regimen. Keep the qualities of each protein source in mind as you choose protein supplements. - 17274
