Whey Protein Comparisons for Blood Lipid Effects

The goal of this clinical trial is to learn if hydrolyzed whey protein can help serum cholesterol stay in normal range in adults. As a side inquiry, a few blood measures will be taken that are relevant to low level inflammation. The main questions the study aims to answer are: * Will hydrolyzed whey lower serum cholesterol readings in adults with starting values in the upper end of normal to the lower end of elevated? * Will the hydrolyzed whey affect a general measure of inflammation and two measures of indirect relevance to inflammation? Researchers will compare hydrolyzed whey to a conventional whey (a control protein not expected to affect serum cholesterol readings) to see if the hydrolyzed whey lowers serum cholesterol. Participants will: * Drink one protein beverage every day for 6 weeks; * Go to a LabCorp facility for a blood draw before and after the 6 weeks.
