Consuming fruits and vegetables is known to lower blood pressure. However, it is unclear how much should be consumed in order to achieve this effect.

A cross-sectional study was conducted among a random sample of 777 adults between the ages of 32 and 38 from the Region of Valparaiso, Chile. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured, and a survey was carried out to quantify consumption trends over the past month.

In the analysis, multiple linear regression models were used and were adjusted for sex, BMI, physical activity, socioeconomic status, smoking, and sodium intake.
