A new research by Harvard University was published Monday in JAMA (Journal of the American Medical Association) Internal Medicine. 118,000 men and women participated in two large studies from which data were gathered since 1984. No person suffered from cancer or cardiovascular disease in the beginning of the studies.
A lower cardiovascular mortality and total mortality was found by researchers. Higher whole grain intake was linked with the results measuring food intake and diet habits by questionnaire every two to four years in this major 14 years study. However, more whole grains weren’t connected with a drop in cancer mortality.
The authors write that “These results are in line with recommendations that promote increased whole grain consumption to facilitate disease prevention”. A five percent lower rate of death from any cause and a nine percent lower rate of death from cardiovascular disease was associated with the consumption of every 28 gram-per-day serving of whole grains according to the estimation of the study. The whole grain in diet includes pasta, whole wheat bread, oatmeal and brown rice.
Dieters and many athletes prefer high whole grain breakfast thanks to the high fiber levels which provide them energy for a longer period of time. Many illnesses and heart disease in particularly seemed to avoid those who ate brown rice, porridge , quinoa and corn. The compares were made with variables such as smoking, different ages, physical activity and body mass index to test the findings, but the results were the same.
Whole grains have an important role in lowering your blood pressure, reducing the risk of diabetes, promoting a healthy gut bacteria, boosting bone mineral density. Beta-glucan, a fiber found in oats only can help protecting against heart diseases. It helps to lower cholesterol level, a fundamental step to protect your heart. Avenanthramide, a bioactive compound found in whole grains, is thought to prevent strokes and heart attacks, stopping fat to form in the arteries.
Many dietary guidelines recommend whole grains, because the high levels of nutrients contained in them like manganese, thiamine, zinc, iron and copper. The boosting of antioxidants levels that combat free-radicals is another benefit.
The new research indicates that, if more people switched to a diet rich in whole grains, each year thousands of lives could be saved.
