fat dairy consumption to lower blood pressure, this is the first to find the relationship among middle-aged adults. Previous studies have focused on children and young adults, Dr. Alvaro Alonso, the lead author of the new study, told Reuters Health. The study included 5,880 adults who ranged in age from 20 to 90 and were free from high blood pressure and cardiovascular disease at the start of the study. Participants completed questionnaires on their diets and other health and lifestyle factors, and the researchers followed up with them two years later to see how many had developed high blood pressure. Overall, 180 people developed the condition during the study period. Those who had reported the highest intake of low-fat dairy -- mostly in the form of skim and reduced-fat milk -- were 54 percent less likely to develop high blood pressure than those with the lowest intakes.
