Eating more whole grains may reduce the risk of premature death, according to a new meta-analysis by researchers from Harvard T.H. Chan School of Public Health. The study found that people who ate the most whole grains (70 grams/day, about 4 servings), compared with those who ate little or no whole grains, had a lower risk of dying during the study period. According to Qi Sun, assistant professor in the Department of Nutrition and senior author of the study:
These findings further support current dietary guidelines that recommend at least 3 daily servings (or 48 grams) of whole grains to improve long-term health and prevent premature death.
