According to research conducted at Harvard University, whole grain cereals reduce risks of developing cardiovascular diseases and increase life expectancy. These foods would be good for the heart and limit the risk of chronic diseases such as type 2 diabetes.
Rich in fiber, the whole grains cereals are best known for their effects on digestion and intestinal transit. Recent studies, however, have uncovered their surprising benefits to the heart and cardiovascular system, in general. This food would also reduce the mortality associated with this type of pathologies.
Health benefits of the whole grain cereals
Unlike refined products (wheat or white rice), whole grains cereals have retained their germ and outer shell. As a result, they are richer in fiber. In general, this type of food contains more nutrients, such as:
- Magnesium – Anti-stress and important element for muscular and nervous systems functioning;
- Vitamin E – Effective antioxidant;
- Vitamins B1, B2, B5, B6, B9 – Beneficial for the brain, muscles, and skin;
- Iron – Combats fatigue;
- Zinc – Stimulates the immune system;
Whole grain cereals reduce risks of developing cardiovascular diseases and increase life expectancy
Led by Professor Qi Sun, researchers at Harvard wanted to see the effects of whole grain cereals on the cardiovascular system. They examined two huge studies involving 74,341 women followed since 1984 and 43,744 men followed since 1986, until 2010.
At the beginning of the work, the participants were all in good health and did not suffer from cardiovascular diseases or cancer.
Scientists have established a link between frequent consumption of whole grain cereals and a reduction in the early mortality rate or risks of developing cardiovascular diseases.
According to the results, which have been published in the journal American Medical Association – Internal Medicine, eating about 28 grams of whole grain cereals per day reduces the premature mortality by 5%. In addition, the risks of developing cardiovascular diseases were reduced by 9%.
Thus, according to the authors, this research “provides promising indications that a diet enriched with whole grain cereals could contribute to an increase in life expectancy” and reduce risks of developing cardiovascular diseases.
