Vegetable and Fruit Consumption in Cardiovascular Health
Summary
Cardiovascular disease remains the leading cause of mortality worldwide, placing urgent emphasis on modifiable dietary factors. A robust body of evidence indicates that regular consumption of a wide array of vegetables and fruits is associated with lower incidence of hypertension, atherosclerosis and overall cardiovascular mortality. These benefits are attributed to multiple bioactive constituents—dietary fibre, potassium, vitamins and diverse phytochemicals—that act synergistically to improve endothelial function, reduce oxidative stress and attenuate chronic inflammation. Epidemiological studies, supported by mechanistic research, demonstrate dose–response relationships whereby increasing daily intake up to recommended levels yields progressively greater cardiovascular protection. Intake variety further enhances this protection by ensuring exposure to different nutrient profiles. Global dietary guidelines now prioritise five or more portions of vegetables and fruits per day, reflecting consensus on their central role in cardiovascular prevention and public health.*
