Ready-to-Eat Cereal Consumption with Total and Cause-Specific Mortality: Prospective Analysis of 367,442 Individuals

Background: Intakes of ready-to-eat cereal (RTEC) have been inversely associated with risk factors of chronic diseases such as cardiovascular disease (CVD), type 2 diabetes, and certain cancers; however, their relations with total and cause-specific mortality remain unclear.Objective: To prospectively assess the associations of RTEC intakes with all causes and disease-specific mortality risk.Design: The study included 367,442 participants from the prospective National Institutes of Health (NIH)–AARP Diet and Health Study. Intakes of RTEC were assessed at baseline.Results: Over an average of 14 years of follow-up, 46,067 deaths were documented. Consumption of RTEC was significantly associated with reduced risk of mortality from all-cause mortality and death from CVD, diabetes, all cancer, and digestive cancer (all p for trend < 0.05). In multivariate models, compared to nonconsumers of RTEC, those in the highest intake of RTEC had a 15% lower risk of all-cause mortality and 10%–30% lower risk of disease-sp...
