Common whole grain products that provide all edible parts of the grain include oatmeal, popcorn, brown rice, whole-wheat flour, sprouted grains and whole-wheat bread.
It is known that whole grains are nutritionally superior to refined grains and richer in dietary fibre, antioxidants and protein.
A study published in The American Journal of Clinical Nutrition tracked the whole grain intake of nearly 29,000 women health care workers in the US. It found that eating just one serving of whole grains every day might prevent high blood pressure, and more servings could slash the risk even further.
When the 10-year study began in 1992, the women were in their early to mid-50s. During the course of the study, a total of 8,722 women were diagnosed with high blood pressure, reported the online edition of health magazine WebMD.
Researchers found that compared to women who reported eating less than half a daily serving of whole grains, women who claimed to eat at least four daily servings of whole grains were about 23 percent less likely to be diagnosed with high blood pressure.
