The lead researcher of the study said: "We observed a decrease in systolic blood pressure in the volunteers who ate the whole-grain foods, and this effect is similar to that you might expect to get from using blood pressure-lowering drugs.
The abstract of the research paper concluded:
Daily consumption of 3 portions of whole-grain foods can significantly reduce cardiovascular disease risk in middle-aged people mainly through blood pressure-lowering mechanisms. The observed decrease in systolic blood pressure could decrease the incidence of coronary artery disease and stroke by 15% and 25%, respectively.
Whole grains for Better Health
Whole grains contain all the essential parts and naturally-occurring nutrients of the entire grain seed, in contrast to refined grains, like white flour, in which most of these have been removed by processing. Without the bran and germ, about 25% of a grain's protein is lost, along with at least seventeen key nutrients.
