Greater adherence to healthy dietary patterns is associated with lower diastolic blood pressure and augmentation index in healthy, young adults.

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.

Arterial Stiffness and Endothelial Function are Comparable in Young Healthy Vegetarians and Omnivores.

Vegetarians (VEG) are reported to have lower body weight, blood pressure (BP), and cardiovascular disease (CVD) risk compared with omnivores (OMN), yet the mechanisms remain unclear. A vegetarian diet may protect the vascular endothelium, reducing the risk of atherosclerosis and CVD. This cross-sectional study compared vascular function between OMN and VEG.

Associations of Ultra-Processed and Unprocessed/Minimally Processed Food Consumption with Peripheral and Central Hemodynamics, and Arterial Stiffness in Young Healthy Adults.

Consumption of ultra-processed food (UPF) replaces the intake of freshly prepared unprocessed/minimally processed food (MPF) and is positively associated with hypertension and cardiovascular disease (CVD). The objective of this observational study was to investigate the relation between () UPF and () MPF with peripheral and central blood pressure (BP), wave reflection, and arterial stiffness. Habitual dietary intake, ambulatory BP, augmentation index (AIx), and pulse wave velocity (PWV) were assessed in 40 normotensive young adults (15 M/25 W; 27 ± 1 y; body mass index 23.

Antioxidant cocktail following a high-sodium meal does not affect vascular function in young, healthy adult humans: a randomized controlled crossover trial.

Chronic high sodium intake is a risk factor for cardiovascular disease as it impairs vascular function through an increase in oxidative stress. The objective of this study was to investigate the acute effects of a high-sodium meal (HSM) and antioxidant (AO) cocktail on vascular function. We hypothesized that a HSM would impair endothelial function, and increase arterial stiffness and wave reflection, while ingestion of the AO cocktail would mitigate this response.

Dietary Potassium Attenuates the Effects of Dietary Sodium on Vascular Function in Salt-Resistant Adults.

The influence of dietary sodium and potassium on blood pressure (BP) has been extensively studied, however their impact on endothelial function, particularly any interactive effects, has received less attention. The purpose of this study was to determine if dietary potassium can offset the deleterious effect of high dietary sodium on endothelial function independent of BP. Thirty-three adults with salt-resistant BP (16 M and 17 F; 27 ± 1 year) completed seven days each of the following diets in a random order: a moderate potassium/low sodium diet (65 mmol potassium/50 mmol sodium; MK/LS), a moderate potassium/high sodium diet (65mmol potassium/300 mmol sodium; MK/HS) and a high potassium/high sodium (120 mmol potassium/300 mmol sodium; HK/HS).

Sodium, hypertension, and the gut: does the gut microbiota go salty?

Recent evidence suggests that the gut microbiota contributes to the pathogenesis of hypertension (HTN). The gut microbiota is a highly dynamic organ mediating numerous physiological functions, which can be influenced by external factors such as diet. In particular, a major modifiable risk factor for HTN is dietary sodium intake.

Pre-meal inulin consumption does not affect acute energy intake in overweight and obese middle-aged and older adults: A randomized controlled crossover pilot trial.

Background: Three-fourths of adults older than 55 years in the United States are overweight or obese. Prebiotics including inulin-type fructans may benefit with weight management.

Aim: We aimed to investigate the acute effects of pre-meal inulin consumption on energy intake (EI) and appetite in older adults.
