Four to six servings of whole grain per day lower risk factors for heart disease
Eating four to six servings of whole grains each day reduces several major risk factors for cardiovascular disease, according to a new study published in the European Heart Journal.

A new study in the European Heart Journal suggests that consuming four to six servings of whole grains daily can lower several risk factors for heart disease. This systematic review and meta-analysis analyzed data from 87 clinical trials involving over 6,500 participants across multiple countries. The research, led by Dr. Helda Tutunchi from Tabriz University of Medical Sciences in Iran, found that a diet rich in whole-grain foods can help reduce body weight, blood pressure, cholesterol levels, and glucose levels in the blood.
Dr. Tutunchi explained that while previous studies had mixed results, this research provides a more definitive answer to the question of how much whole grain is needed for significant cardiovascular health improvements. The analysis showed the greatest benefits when participants consumed 60 to 100 grams of whole grains per day, which is equivalent to four to six servings.
Examples include a bowl of oatmeal, a sandwich made with whole-grain bread, and a serving of brown rice. However, the beneficial effects may only be seen in the short term, as most included trials lasted about eight weeks. Further long-term studies are needed to confirm these findings.
