BACKGROUND: Consuming a diet rich in plant-based foods (PBFs) may be protective for risk of metabolic syndrome (MetS) and chronic disease. However, the impact of consuming healthy versus all types of PBF on MetS is unknown. METHODS: The relationship between consumption of PBF (both healthy and all) was examined using data from the 2015 to 2016 National Health and Nutrition Examination Survey (NHANES). The amount of PBFs consumed was calculated as average daily servings, whereas dichotomous MetS variables were based on the National Cholesterol Education Adult Program Treatment Panel III (2005). After weighting and multiple imputation, adjusted associations were examined using logistic regression and marginal probabilities. RESULTS: Consumption of healthy PBF was significantly associated with reduced risk for elevated waist circumference (P = 0. 017; odds ratio, OR 0. 96, 95% confidence interval, CI 0. 94-0. 98) and MetS (P = 0. 006; OR 0. 96, 95% CI 0. 93-0. 99). Interactions revealed significant protective effects for females who were 60 years. CONCLUSIONS: In the adjusted model, a 1-unit increase in daily servings of healthy PBF was associated with a 4% lower risk for prevalence of elevated waist circumference and a 4% decrease in risk for prevalence of MetS. Increasing consumption of PBF may offer a viable strategy for reducing risk of MetS.
