New research suggests that flavan-3-ol, a natural compound found in tea and chocolate, may benefit people with high blood pressure.
The findings, published in the European Journal of Preventive Cardiology, highlight the potential of this plant-based substance in managing hypertension through diet.
While prescription medications are often the first line of defense against high blood pressure, certain everyday foods may contain compounds that offer similar benefits. Flavan-3-ol is one such compound. Naturally present in tea, dark chocolate, cocoa, apples, and grapes, it has long been linked to improved vascular health.
To explore its effects more thoroughly, researchers from the University of Surrey reviewed 145 randomized controlled trials. Their analysis focused on how regular consumption of flavan-3-ol influenced individuals with elevated blood pressure.
The results were compelling. Participants who consistently included flavan-3-ol-rich foods in their diets experienced significant reductions in blood pressure. In some instances, the improvements were comparable to those produced by standard antihypertensive medications.
In addition to lowering blood pressure, flavan-3-ol was also shown to enhance endothelial function, an essential aspect of cardiovascular health. Remarkably, this benefit occurred regardless of whether blood pressure levels changed.
The researchers emphasized that these health gains can be achieved through accessible and familiar foods such as tea, apples, dark chocolate, and cocoa powder.
They concluded that flavan-3-ol helps manage hypertension and supports overall heart health, offering a natural and straightforward way to improve well-being through diet.
