Key Findings: There was a significant inverse relationship between total nut intake and risk of cancer. Highest nut consumption was associated with a 13% lower risk. There was a weaker association between peanut consumption and cancer risk. Authors added, "In terms of cancer mortality, we found 13%, 18%, and 8% risk reductions with higher intakes of total nuts, tree nuts, and peanuts, respectively. In addition, a 5-g/d increase in total nut intake was associated with a 4% lower risk of cancer mortality. In conclusion, our findings support the protective association between total nut and tree nut intake and the risk of cancer and its mortality." In general, peanut butter intake was not associated with cancer risk in the studies identified.
