The Case for Whey
There appears to be a scientific consensus developing regarding the health benefits of whey protein. Another study was recently released with more compelling findings about whey. Researchers at the University of Toronto recently reviewed all of the existing literature on whey protein, appetite, and eating. They came to a firm conclusion, which was formulated as follows in a paper published in the Journal of the American College of Nutrition: "Whey protein has potential as a functional food component to contribute to the regulation of body weight by providing satiety signals that affect both short–term and long–term food intake regulation."
According to this paper, whey protein achieves these important benefits through several different mechanisms. For example, some of the peptides, or protein fractions, in whey protein stimulate the release of gut hormones that create a feeling of satiety, or fullness. Whey protein also reduces appetite by increasing blood amino acids levels. It also helps regulate insulin levels
Whey protein is a natural component of dairy foods, but the University of Toronto researchers suggested that whey protein supplements, such as ProEnergy, are probably more effective, because they contain much higher levels of whey protein and much less fat and carbohydrate.
So, if you´ve been waiting to add protein shakes to your diet until the final results were in, wait no longer. Case closed: whey protein works!
