Objectives:
Epidemiologic studies have investigated the association between nut intake and risk for multiple cancers. However, current findings are inconsistent and no definite conclusion has been drawn from prospective studies. Therefore, this review article has been conducted.
Does nut consumption reduce cancer risk?
Study design:
This review article included 33 cohort studies with more than 50,000 cancer cases.
Results and conclusions:
The investigators found when comparing the highest with the lowest category of nut consumption, high consumption of nuts significantly decreased risk of overall cancer with 10% [RR = 0.90, 95% CI = 0.85-0.95].
Significant association was only obtained for intake of tree nuts.
The investigators found when comparing the highest with the lowest category of nut consumption, high consumption of nuts significantly decreased risk of cancer from the digestive system with 17% [RR = 0.83, 95% CI = 0.77-0.89].
The investigators found per 20 g/day increase in nut consumption was related to a 10% [RR = 0.90, 95% CI = 0.82-0.99] decrease in cancer risk.
The investigators concluded that consumption of 20 grams of tree nuts per day reduces cancer of the digestive system.
