This study reviewed the current evidence surrounding food groups and risk of colorectal cancer. Authors looked at 12 major food groups, including nuts.
In the subgroup analysis, nut consumption was associated with reduced risk of colon cancer. Although there was no association with rectal cancer, authors suggest that this may be because there are few studies on nut consumption and rectal cancer. More studies are needed in this area. However, evidence from this review indicates that nut consumption may lower colon cancer risk.
