Five Foods Proven to Lower High Blood Pressure and Reduce Stroke Risk, According to Doctor

High blood pressure affects roughly one in three adults in the UK—about 14 million people—with nine million diagnosed by their GPs, according to the British Heart Foundation. If left unmanaged, elevated blood pressure significantly increases the risk of heart attacks, strokes, and vascular dementia. Fortunately, diet plays a crucial role in controlling blood pressure levels.

Dr. Sethi, a gastroenterologist trained at Harvard and Stanford, shared on TikTok five foods scientifically shown to help lower and prevent high blood pressure:

Bananas: Rich in potassium, bananas help the kidneys eliminate excess sodium from the body. Because high sodium intake can elevate blood pressure, potassium-rich foods support a healthier balance and help reduce hypertension.

Dark Chocolate: Packed with magnesium and flavanols, dark chocolate boosts the production of nitric oxide, a molecule that relaxes blood vessels and improves blood flow. Studies suggest dark chocolate is especially beneficial for older adults and individuals at higher cardiovascular risk.
Beetroot: Similar to dark chocolate, beetroot contains organic nitrates that the body converts into nitric oxide. Regular consumption, such as drinking 250ml of beetroot juice daily, has been linked to blood pressure levels returning to normal, according to British Heart Foundation research.
Pomegranates: These fruits reduce blood pressure by inhibiting the angiotensin-converting enzyme (ACE), which controls the diameter of blood vessels. Lower ACE activity helps prevent blood vessels from constricting, thereby easing blood flow and reducing hypertension.
Ginger: Acting as a natural calcium channel blocker, ginger relaxes blood vessels and improves circulation by limiting calcium entry into heart cells. A 2017 study found that daily ginger consumption was associated with a decreased risk of high blood pressure.

If you have concerns about your blood pressure, the NHS recommends booking an appointment with your GP or visiting a local pharmacy for a pressure check. Incorporating these five foods into your diet could be a delicious and effective way to support heart health.
