This Food Prevents High Blood Pressure

Quick! Go get a glass of skim milk and a container of low-fat yogurt. The new must-eat health food may be low-fat dairy foods.

A two-year study of nearly 5,900 adults who ranged in age from 20 to 90 years old concludes that middle-aged adults who drink skim milk and eat other low-fat dairy foods have lower blood pressure than others their age. Mind you, these dairy foods don't lower high blood pressure, but rather seem to prevent it from ever occurring.

Researchers from the University of Navarra in Pamplona, Spain found that those who had the highest intake of low-fat dairy products were 54 percent less likely to develop high blood pressure as those who consumed the fewest, reports Reuters. Even when other factors, such as overall diet, exercise, body weight and smoking, were included, the amount of dairy foods in the diet had a significant protective effect against hypertension. What didn't have an impact were high-fat dairy foods, such as whole milk and ice cream.

Lead study author Dr. Alvaro Alonso, who is now with the Harvard School of Public Health in Boston, told Reuters that while previous research has linked low-fat dairy consumption to lower blood pressure in children and young adults, this is the first study to focus on middle-aged adults, a time of life when blood pressure often spikes.

It's important to note that the study conclusions do not prove that low-fat dairy foods have a direct benefit on blood pressure, but the results are tantalizing even if it's not clear why they have this effect. While calcium surely plays some role, it's not the only magic ingredient. The research team speculates that the proteins in milk, including caseins and whey, may act much like drugs that lower blood pressure by converting enzyme, or ACE, inhibitors.

But does it have to be low-fat dairy? Yes! Alonso thinks it's plausible that the saturated fat in richer dairy foods neutralizes any blood pressure benefits.

The study findings were published in the American Journal of Clinical Nutrition.
