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 isn't the same for everyone and can't be generalized to every type of yogurt.
Plain yogurt can be part of a heart-healthy diet. However, it does not 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. It is not only involved in digestion, but is 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 suggests that certain probiotics may slightly lower blood pressure. Clinical studies mainly tested products containing selected Lactobacillus species. In some studies, blood pressure readings decreased, while other studies found no clear effect.
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.
Therefore, the results to date do not support using yogurt as a treatment for high blood pressure. Rather, they show that certain probiotic cultures may have a complementary 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 body's natural gut barrier. This may allow fewer inflammation-promoting components from gut bacteria to enter the bloodstream. However, it is still not fully clear which of these mechanisms is truly decisive in humans.
Does the effect apply to every yogurt?
No. Conventional yogurt is not automatically comparable to the probiotic products investigated in studies. The bacterial strains it contains, their quantity, storage, and duration of consumption may be important.
Also, the label "probiotic" does not mean that a product has been proven to lower blood pressure. It is currently still not sufficiently clear which bacterial species are particularly effective, what the optimal dosage is, and how long such 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, heavily sweetened fruit yogurts and dessert products often contain a lot of sugar. They offer no particular benefit for cardiovascular health. That's why it's worth checking the list of ingredients and the nutrition information when shopping.
For people with high blood pressure, it is not a single food that matters, but their overall diet. The DASH diet, for example, can provide guidance. Consuming less salt over the long term can also 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 cannot be applied across the board to every type of yogurt. It is 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. However, yogurt or probiotics alone are not enough to treat high blood pressure. A balanced diet, regular physical activity, as little salt as possible, regular blood pressure checks, and taking medications prescribed by a doctor remain essential.
