In a nutshell
- Dark chocolate, tea, apples, and grapes can significantly lower blood pressure, especially in people with hypertension, with effects comparable in size to standard medications.
- These flavan-3-ol-rich foods also improve blood vessel function, offering heart health benefits beyond just blood pressure reduction.
- Whole foods work better than supplements, and they come with minimal side effects, making them a safe, affordable addition to a heart-healthy lifestyle.
GUILDFORD, England — Instead of buying the next trendy expensive supplement or exotic superfood, a morning cup of tea could do more for your blood pressure than you realize. A new international study suggests that certain foods, like tea and dark chocolate, pack enough cardiovascular punch to rival prescription medications—at least for people who need them most.
Researchers analyzed 145 clinical trials involving over 5,000 participants and found that foods rich in compounds called flavan-3-ols can slash blood pressure by amounts comparable to many hypertension drugs. In people with high blood pressure, consuming these foods daily dropped their readings by about 6 points systolic (the top number) and 3 points diastolic (the bottom number), similar to what doctors see with standard medications.
The study, published in the European Journal of Preventive Cardiology, examined foods that most Americans already know and love: dark chocolate, tea (both green and black), apples, and grapes. Unlike studies that test isolated compounds in lab settings, this analysis looked at actual foods people can easily incorporate into their daily routines.
Blood pressure benefits weren’t the only good news. These foods also improved how well blood vessels function, measured through a test called flow-mediated dilation, which is how well arteries expand when blood flows through them. This effect occurred regardless of blood pressure changes, suggesting that flavan-3-ols might offer cardiovascular protection beyond just lowering the numbers on a monitor.
The research team combed through medical databases for studies published between 1946 and 2024. They included only randomized controlled trials, the gold standard for medical research, that tested flavan-3-ol-rich foods against placebos.
Bigger Benefits for Those Who Need It Most
The trials varied widely in design and duration, from single-dose studies measuring immediate effects to longer trials lasting up to 26 weeks. Participants ranged from healthy volunteers to people with existing cardiovascular disease, diabetes, or hypertension. This diversity actually strengthens the findings, showing that benefits appear across different populations and health conditions.
Breaking down the effective doses, the average intervention delivered 586 milligrams of total flavan-3-ols daily. Dark chocolate studies typically used about 56 grams (roughly two ounces) of chocolate with 75% cocoa content. Tea studies provided around 700 milliliters (about three cups) daily. Apple studies used about 340 grams, roughly two medium apples.
Researchers found that blood pressure benefits were most pronounced in people who needed them most. Those with normal blood pressure saw minimal changes, but people with elevated readings or diagnosed hypertension experienced significant drops. This mirrors how prescription blood pressure medications work; they’re most effective in people with higher baseline readings.
They also examined isolated compounds versus whole foods. Studies using purified epicatechin (the main flavan-3-ol in cocoa) or EGCG (common in green tea) showed weaker effects than studies using actual chocolate or tea. This suggests that the benefits come from the complex interplay of compounds in whole foods, not just single active ingredients.
Flow-mediated dilation improved by about 2% on average. This might sound small, but research has shown that every 1% improvement in this measure corresponds to a 10% reduction in cardiovascular disease risk.
Across all studies, only 0.4% of participants reported adverse effects, mostly minor stomach upset or headaches that resolved on their own. Many medications, on the other hand, often come with significant side effects.
Currently, the American Heart Association and similar organizations recommend limiting sodium, increasing physical activity, and following dietary patterns like the Mediterranean diet to manage blood pressure. Actively including specific flavan-3-ol-rich foods could be equally important, too.

I hate to tell you, but cholesterol does nothing bad and does not cause disease. Lowering cholesterol is meaningless. Look up Jupiter trial.
Holesyerol does nothing bad, not associated with any disease and lowering does nothing.
