Aiding weight loss: In one study of 158 people, published in Nutrition & Metabolism, those who were given whey “lost significantly more body fat and showed a greater preservation of lean muscle compared to subjects consuming the control beverage.”
Anti-cancer properties: Promising results were published in the journal Anticancer Research for the use of whey protein concentrate in cancer treatment. More research is needed.
Lowering cholesterol: A study, published in The British Journal of Nutrition, gave whey supplements to 70 overweight men and women for 12 weeks and measured several parameters, such as lipid and insulin levels. They found that “there was a significant decrease in total cholesterol and LDL cholesterol at week 12 in the whey group compared with the casein (group).”
Asthma: Whey protein could improve the immune response in children with asthma.
