Consuming more nuts, particularly tree nuts, may help reduce the risk of cardiovascular disease (CVD) among people with type 2 diabetes (T2D), according to a new study in Circulation Research.
The prospective analysis included 16,217 men and women with either prevalent diabetes at baseline or diagnosed during the course of the study. Consumption of nuts was assessed using a validated food frequency questionnaire.
During follow-up, there were 3,336 incident CVD cases and 5,682 deaths. The study found that compared to people with T2D who ate less than a single 28-gram serving per month, eating five servings of nuts per week was associated with a 17 per cent lower risk of total CVD, a 20 per cent lower risk of coronary heart disease (CHD), a 34 per cent lower risk of CVD mortality, and a 31 per cent reduced risk of all-cause mortality.
Furthermore, a greater increment in nut consumption from pre to post diagnosis was also significantly associated with lower risk of subsequent CVD events and mortality.
Analysis for specific types of nuts showed higher tree nut consumption was associated with lower risk of total CVD, CVD mortality, CHD incidence, cancer-related and all-causes mortality. Peanut consumption was associated with lower all-cause mortality only.
