Does yogurt help with high blood pressure?

Many people with high blood pressure wonder whether plain yogurt can lower their blood pressure. In fact, scientific studies suggest that certain probiotics may have a small positive effect on blood pressure. However, the effect isnt the same for everyone, and it cant be assumed for every type of yogurt.

Plain yogurt can be part of a heart-healthy diet. But it doesnt replace a healthy lifestyle or doctor-prescribed treatment for high blood pressure.

Why might yogurt affect blood pressure?

Yogurt is made by fermenting milk with lactic acid bacteria. Some of these bacteria are considered probiotics. These are living microorganisms that, in sufficient amounts, may provide health benefits.

Many different microorganisms live in the gut. This community is called the gut microbiome or gut flora. Its not only involved in digestionits also connected with metabolism, the immune system, and the health of blood vessels.

In people with high blood pressure, studies have observed changes in the gut microbiome. For example, the formation of short-chain fatty acids may be reduced, and the protective function of the gut barrier may be impaired. This could allow inflammation-promoting substances to enter the bloodstream more easily and support processes involved in the development of high blood pressure.

Can yogurt really lower blood pressure?

Current research provides indications that certain probiotics may slightly lower blood pressure. In clinical studies, researchers mainly tested products containing selected Lactobacillus strains. In some studies, blood pressure values decreased, while in other studies no clear effect was found.

Note: However, this range should not be understood as the expected effect of regular yogurt. The products studied, the bacterial strains, the doses, and the length of time taken differed significantly.

In addition, certain groups of people responded differently to probiotics. In some older people with high blood pressure, in smokers, or in women after menopause who have metabolic syndrome, sometimes there was no blood pressure reduction.

So the existing results do not suggest using yogurt as a treatment for high blood pressure. Instead, they indicate that certain probiotic cultures may have an additional beneficial effect.

How could probiotics affect blood pressure?

Researchers discuss several possible mechanisms. Certain lactic acid bacteria may produce substances that inhibit the angiotensin-converting enzyme (ACE). This enzyme plays an important role in regulating blood pressure.

Some probiotics may also promote the production of nitric oxide. Nitric oxide helps blood vessels relax and can improve vessel function. Anti-inflammatory, antioxidant, and immune-regulating effects are also being studied.

Another possible approach is strengthening the bodys natural gut barrier. This may allow fewer inflammation-promoting components from gut bacteria to enter the bloodstream. However, its still not fully clear which of these mechanisms is truly decisive in humans.

Does the effect apply to every yogurt?

No. A typical yogurt isnt automatically comparable to the probiotic products studied in research. What matters can be the bacterial strains it contains, the amount, how its stored, and how long you eat it for.

Also, the label probiotic doesnt necessarily mean that a product has been proven to lower blood pressure. Right now, its not yet clear which bacterial species are particularly effective, what the optimal dose is, and how long a product would need to be taken.

Another factor is that many studies on yogurt intake are observational studies. They can show a link between regularly eating yogurt and lower blood pressure values, but they cannot prove a clear cause. People who often eat plain yogurt may, overall, follow a more balanced diet and pay more attention to their health.

Which yogurt is recommended?

If you like eating yogurt, you can include plain yogurt without added sugar as part of a balanced diet. Fresh fruit, oats, or unsalted nuts can be good additions.

On the other hand, strongly sweetened fruit yogurts and dessert products often contain a lot of sugar. They dont offer a special advantage for heart and circulation health. Thats why its worth checking the ingredient list and the nutrition information when shopping.

For people with high blood pressure, its not a single food that matters, but your overall diet. One example you can use is the DASH diet. Also, keeping salt intake lower over the long term can help lower blood pressure. More information is available in the article Blood pressure and salt.

Our bottom line

Certain probiotics may slightly lower blood pressure. In particular, selected Lactobacillus strains show possible positive effects in studies on the gut microbiome, inflammation processes, and blood vessel function.

However, the results cant be applied across the board to every type of yogurt. Its still unclear which bacterial strains, amounts, and intake schedules provide the greatest benefit. And not everyone responds in the same way.

Plain yogurt without added sugar can be part of a heart-healthy diet. But yogurt or probiotics alone arent enough to treat high blood pressure. A balanced diet, regular physical activity, ideally less salt, regular blood pressure checks, and taking doctor-prescribed medications remain essential.
