MedPage Today reports, “Individuals eating three daily servings of whole grains had a significantly, though modestly, lower risk of colorectal cancer, according to pooled data from nearly 800,000 individuals — perhaps the largest and strongest analysis ever conducted.”
Researchers found that “a 90-gram per day increase in dietary fiber from whole grains — the amount a person would consume from three servings — was associated with a risk reduction of 17% (95% CI 11% to 22%) for colorectal cancer.”
The study, published online in BMJ, “also found that ‘high’ versus ‘low’ intake of total dietary fiber was associated with a significant reduction in risk (12%, 95% CI 6% to 18%).”
