Protein is an essential building block for our bodies. It is found in many foods including meats, dairy, eggs and beans. People following
an active lifestyle including working out with weights can easily add to their protein intake through supplements.
are the preferred type of protein. Their rapid absorption makes them an excellent choice for postworkout nutrition. Several
studies have shown that hydrolysates (specifically, whey) are better retained by the body and have positive impacts on immune system function.
Whey protein is also the highest biologically rated protein, the most effective in the body. The combination of this with the hydrolysation
process will ensure you are getting high quality protein. They are much more efficient in the body than regular (food) proteins.
There are three different types of whey proteins; Whey protein isolates, whey protein concentrates, and whey blends. Whey Protein Isolate
powders go through the most rigorous filtering process to remove just about all fat and carbohydrates. In general, these powders will contain
a higher percentage of protein compared to whey protein concentrate - around 90% protein, up to 97% for some whey isolates. They are also the most expensive of the three.
Whey Protein Concentrate
(generally around 75% to 80% protein) is much more economical than the Isolates because the process of removing
most of the carbs and fat is relatively inexpensive, compared to getting the maximal amounts out to isolate the protein. Blended whey protein
powders contain blends of various protein sources - including whey protein. These are recommended for general use throughout the day and
at bed time.
is derived from soybeans, which have a higher protein content than any other legume. Approximately 38% of the soy bean is
protein, however, when the beans are highly refined to reveal the most proteinaceous fraction of the bean, soy protein isolate is the
result. Isolated soy is the most concentrated source of soy protein and yields more than 90% protein. Soy proteins provide all the
essential amino acids needed to fulfil human nutritional requirements for growth, maintenance, and physical stress. I am not a huge fan of soy protein, but if
you want a vegetarian protein, look for a blend of rice and pea protein
Eggs have long been a preferred source of protein for body builders and athletes. Egg protein
can be had by eating whole eggs,
pasturized egg whites and egg protein powder. In powdered form it provides an excellent source of high biological value protein without
the excessive fat and cholesterol, associated with whole eggs.
