Other Covariates

Participants self‐reported age, sex, and race. We collected data on antihypertensive medication use at each study visit and we dichotomized antihypertensive medication use [yes/no]. We measured weight at each visit using a digital scale without shoes. We measured height was measured at the study entry, and calculated BMI using height and weight (kg/m²). Participants filled out a fruit and vegetable screening questionnaire (National Cancer Institute Eating at America’s Table Study Quick Food Scan) at each study visit. We estimated fiber intake (in grams) using a regression model based on self‐reported fruit/vegetable/legume intake, age, and sex.
