Nut and Peanut Butter Consumption and the Risk of Total Cancer: A Prospective Cohort Study.

Abstract

Nut intake has been associated with reduced cancer-related mortality, but there is very limited evidence on total cancer risk. We investigated the associations of nut and peanut butter intake with the risk of total cancer and smoking- and alcohol-related cancer subgroups. In the prospective Netherlands Cohort Study, 120,852 men and women aged 55 to 69 years provided information on lifestyle and dietary habits at baseline in 1986. After 20.3 years of follow-up, 19,255 total cancer cases and 3,499 subcohort members were included in multivariable-adjusted Cox regression analyses, using a case-cohort approach. No significant associations were found between total nut, tree nut, peanut, and peanut butter intake and total cancer risk in men and women. There were also no significant associations with smoking-(un)related and alcohol-(un)related cancers in both sexes. Our findings suggest that nut and peanut butter intake are not associated with a reduced risk of total cancer in men or women. Nut and peanut butter consumption are not related to the risk of total cancer.
