As fitness & nutrition gurus in the Atlanta area, we hear questions like these pretty frequently... "What's all this buzz about protein? Why are there so many products out there? Which is the best type of protein to have?"
So to answer some of these questions, ATL Fitness Club has some helpful info for you to read in order to point you in the right direction!
Whey protein is a mixture of proteins isolated from whey, which is the liquid material created as a byproduct of cheese production. Whey protein typically comes in three major forms: concentrate, isolate, and hydrolysate.
Whey concentrates contain a low level of fat and cholesterol but, in general, have higher levels of carbohydrates in the form of lactose. Supplements containing whey protein concentrate help satiate you, which means it can hold you over longer in between meals.
Whey isolates are processed to remove the fat, and lactose, but are usually lower in bioactivated (plant/food) compounds. Supplements containing whey protein isolate get into your system fastest, which is helpful in the recovery process after working out.
Whey hydrolysates are predigested, partially hydrolyzed whey proteins that are more easily absorbed, but their cost is generally higher. They are also very bitter in taste, which may be why most protein supplements on the market are typically not formulated with this type of whey.
To sum it up, whey is essential in the fitness industry today because of its efficient ability to build muscle very quickly.
Whey protein supplements like shakes and bars are most commonly used after workouts to help increase levels of amino acids in the blood, which are taken up by the muscles.
A recent study of athletes showed that during exercise, whey protein actually improves the flow of nutrients to areas of the body which help repair and rebuild muscle tissues.
Researchers suggest whey protein supplementation, in conjunction with exercise, can provide great benefits to lean muscle mass growth and muscle maintenance.
