Abstract
- More than two-thirds of cardiovascular disease (CVD) deaths worldwide are attributable to dietary factors. Blood pressure variability (BPV), endothelial dysfunction, and arterial stiffness are important CVD risk factors. Although studies show a link between consuming a healthy diet and lower BPV and stiffness and improved endothelial function, research in young, healthy adults is scarce. We hypothesized that, in young, healthy adults, diet quality would be inversely associated with BPV and arterial stiffness and positively associated with endothelial function. This cross-sectional study included 56 healthy young adults (34 women/22 men, age 26.7 ± 0.8 years, body mass index 23.4 ± 0.4 kg/m2, blood pressure [BP] 113/69 mmHg). Three-day diet records were used to calculate two Dietary Approaches to Stop Hypertension (DASH) diet scores, the alternative Mediterranean Diet (aMED) score, and the Healthy Eating Index-2015 (HEI-2015) based on the 2015-2020 Dietary Guidelines for Americans. Twenty-four-hour ambulatory BP data were used to calculate average real variability of systolic and diastolic BP. Endothelial function was assessed by flow-mediated dilation, and arterial stiffness was assessed by pulse wave velocity and augmentation index (AIx). Overall, the HEI-2015 was inversely associated with 24-hour diastolic BP (DBP) and daytime DBP, and the aMED score was inversely associated with AIx. In our exploratory analyses, the Fung DASH score was inversely associated with 24-hour DBP and daytime DBP in women, but not men. These findings suggest that consuming a diet that aligns with the DASH diet, the Mediterranean diet, and/or the 2015-2020 Dietary Guidelines for Americans is associated with cardiovascular benefits in healthy, young adults. The relation between diet quality and blood pressure (BP) and vascular health in healthy adults is understudied. Adherence to the Mediterranean Diet was inversely associated with augmentation index; adherence to the Dietary Guidelines for Americans was inversely associated with diastolic BP; and adherence to the Dietary Approaches to Stop Hypertension diet was inversely associated with diastolic BP in women. Consuming a healthy dietary pattern is associated with improved cardiovascular disease risk factors in healthy, young adults. [Display omitted] [ABSTRACT FROM AUTHOR]
