May be beneficial for inflammatory bowel disease and other benefits

Inflammatory bowel disease (IBD) is a condition that causes chronic inflammation in the digestive system lining. It refers to both Crohn's disease and ulcerative colitis. Whey protein supplementation has been shown to help with IBD in both mice and people. However, the present evidence is weak, and more research is needed before making any firm claims.

High LDL (bad) cholesterol, in particular, is a risk factor for heart disease. In one 12-week research of overweight people, 65 grams of whey protein per day resulted in a considerable reduction in total and LDL cholesterol. Other investigations on blood cholesterol found no such impact. Differences in study design could explain the lack of effect. Finally, more research is required before any conclusions can be drawn.
