Lower your blood pressure with a vegan diet

A vegan diet can help reduce blood pressure

Changing your diet is an effective way to lower your blood pressure and there is robust evidence to show that a vegan diet can help to do that. Many studies, including the EPIC‑Oxford study, found that vegans have lower levels of high blood pressure than meat-eaters, fish-eaters and vegetarians. Vegan diets probably work via a combination of factors, including the beneficial effects of fibre, vitamins A, C and E, antioxidants, polyunsaturated fats and minerals – phosphorus, calcium, magnesium and potassium, in particular.

Moving from animal to plant‑based foods can also alter the gut microbiota, decreasing production of toxic metabolites. So-called nutraceuticals, such as beetroot juice, magnesium, vitamin C, catechin‑rich beverages (green tea) or soya isoflavones may also help.

Another review, looking at fifteen studies with over 800 participants, also found that vegetarian diets significantly lowered blood pressure – a vegan diet was even more effective.

Dr. Justine Butler
I joined Viva! as a health campaigner in 2005 after graduating from Bristol University with a PhD in molecular biology. My scientific training helped me research and write numerous reports, guides and fact sheets for Viva! including Meat the Truth, Fish-Free for Life, One in Nine (breast cancer and diet) and the substantial report on the detrimental health effects of consuming dairy; White Lies. This accompanied Viva!’s report The Dark Side of Dairy which spelt out the inherent cruelty of dairy farming. We were the first UK group to take on the dairy industry in this way, and many of our supporters go vegan after reading these reports.
