Synopsis

Rating (out of 5): 2

Beet (Beta vulgaris), particularly in the form of beetroot juice, is increasingly studied for its cardiovascular benefits, including potential support for arteriosclerosis (the thickening and hardening of arterial walls). The scientific rationale centers on beet’s high nitrate content, which the body converts to nitric oxide—a molecule that helps relax and dilate blood vessels, improve endothelial function, and lower blood pressure. These effects could theoretically slow the progression of arteriosclerosis or reduce its risk factors.

Several small clinical trials and epidemiological studies suggest that regular consumption of beetroot juice can modestly lower blood pressure and improve vascular function in both healthy individuals and those with hypertension. For example, a 2015 review in Hypertension concluded that dietary nitrate from beetroot can improve vascular health and reduce blood pressure. However, direct evidence supporting beet as a treatment for arteriosclerosis specifically (rather than its risk factors like hypertension or endothelial dysfunction) remains limited. Most studies are short-term, involve small sample sizes, and focus on surrogate markers rather than clinical outcomes related to arterial hardening or plaque development.

In summary, while there is scientific plausibility and some preliminary human evidence supporting beet’s cardiovascular benefits, robust clinical evidence directly validating its use for arteriosclerosis is lacking. Thus, its use is supported by emerging scientific data but still requires further high-quality trials to confirm efficacy for this specific condition.
