 Study Finds Health Benefit in Whey Protein Drinks  

Fluegel S. Int Dairy J. 2010;doi:10.1016/j.idairyj.2010.06.005.

Beverages supplemented with whey protein were associated with lower BP in young adults who had slightly elevated blood pressure or prehypertension, according to researchers from Washington State University.

“Due to the side effects of pharmacological treatment, many people are interested in using diet to control hypertension,” the researchers wrote. “Dairy products contain compounds and minerals that may lower blood pressure, and consumption of dairy and fermented milk products has been associated with lower blood pressure.”

The researchers created whey beverages using whey protein concentrate 80 (WPC80 TemPro, Leprino Foods). Half of the beverages also contained supplemental whey protein, whereas the other half of the beverages served as the control group. Volunteers were recruited using advertisements. The study population was students aged 18 to 26 years, whose BP measurements were taken at the initial screening.

The students were randomly assigned to consume either 28 g per day of the control whey beverage or 28 g per day of the beverage with supplemental protein (along with consuming a normal diet). Among the 71 students enrolled, 25 had normal systolic and diastolic BP at baseline, 42 had prehypertension and four had stage I hypertension.

After 6 weeks of consuming the whey beverages, there was no difference in systolic BP, diastolic BP or mean arterial pressure between the two groups. In the young adults who began the study with elevated diastolic BP and/or systolic BP, the consumption of the whey beverages decreased the systolic BP by 8 mm Hg, decreased the diastolic BP by 8.6 mm Hg and decreased the mean arterial pressure by 6.4 mm Hg.

“The average BP decreases seen in this study are significant from a public health point of view,” the researchers wrote. “Similar decreases in systolic BP and diastolic BP have been associated with large reductions in the risk of stroke, heart disease and overall mortality.”
