Vegetarian Diets and Cardiovascular Risk in Women

Abstract

Introduction: Vegetarian diets have favorable effects on cardiovascular risk, provided that they do not contain ultra-processed foods (UPF).Objective: To compare the metabolic profile, cardiovascular risk, body composition, and food consumption in vegan (VEG), lacto-ovo vegetarian (LOV), and omnivorous (OMNI) women. To verify the association between UPF consumption and cardiovascular risk.Methods: Cross-sectional study with 119 VEG (n = 43), LOV (n = 38), and OMNI (n = 38) women. Anthropometric and biochemical parameters and the Framingham risk score were assessed. Food consumption was assessed by means of a 3-day food register, and intake of macronutrients, micronutrients, and UPF was estimated. The correlation between UPF consumption and cardiovascular risk was assessed using Spearman's coefficient, with a significance level of 5%. Results:The groups showed low cardiovascular risk, without significant difference between them. The VEG and LOV groups had lower body mass index, neck circumference, body shape index, and systolic blood pressure (p < 0.05) than the OMNI group; greater consumption of carbohydrates, sugars, dietary fibers, micronutrients, betacarotene, and carotenoids; and lower consumption of total fat, saturated fatty acids, and cholesterol (p < 0.05). Consumption of UPF was lower in the LOV group (5.7 [0.0-19.8]) than in the OMNI group (14.9 [5.1 -22.3]; p < 0.05). UPF consumption was associated with SBP (ρ = 0.439; p = 0.007) and blood sugar (ρ = 0.422; p = 0.010) in the VEG group, and in the LOV group it was inversely associated with LDL-c (ρ = −0.456; p = 0.010). Conclusion:Vegetarian women showed better body composition and dietary quality than OMNI women. It is important to take consumption of UPF in vegetarians into consideration, in order to improve cardiovascular risk in women.

“…Body composition was studied by calculating AVI, LAP, and BRI. (50) The AIP is an important predictor of atherosclerosis and CVD risk; it is also superior to the standard atherosclerotic lipid profile. (15) Caminhotto and others documented a CVD risk reduction; i.e.…”
