"Background and Purpose: Several prospective cohort studies and a randomized clinical trial have shown the beneficial effects of peanut consumption on cardiovascular disease and its risk factors. We examined the association between peanut consumption and risk of cardiovascular disease in Japanese men and women. Methods: We analyzed data of 74 793 participants aged 45 to 74 years who completed a lifestyle questionnaire including the validated food frequency questionnaire in the Japan Public Health Center–based Prospective Study. They were followed up from 1995 to 2009 for cohort I and from 1998 to 1999 to 2012 for cohort II. Peanut consumption was calculated from the food frequency questionnaire, and the end points were incidence of stroke, ischemic heart disease, and cardiovascular disease (stroke and ischemic heart disease)."

Key Findings

Key Findings: "Higher peanut consumption was associated with reduced risk of stroke, especially ischemic stroke, but not ischemic heart disease in Japanese men and women."
