Harvard research on whole grain diet

Whole grains are recommended in official U.S. diet guidelines ... but it's been unclear whether, or how much, diets high in whole grains impact death risk.

The study was led by Hongyu Wu, Ph.D., of the Harvard School of Public Health. He and his coauthors examined data from two large studies:
The Nurses' Health Study (1984-2010), involving 74,341 women
The Health Professionals Follow-Up Study (1986-2010), involving 43,744 men
All the participants were free of cancer and CVD when the studies began.

After the data were adjusted to account for potential confounding factors, the results linked diets higher in whole grains with lower risk of death and death from CVD … but not to reduced risk of death from cancer.

The authors estimated that every serving (28 grams/per day) of whole grains dropped the risk of death by five percent, and reduced the risk of death from CVC by nine percent.

As they wrote, “These findings further support current dietary guidelines that recommend increasing whole grain consumption … and [suggest that] a diet enriched with whole grains may confer benefits toward extended life expectancy.” (Wu H et al. 2015)
