Kefir is a milk-fermented drink, containing many beneficial bacteria, vitamins and biological compounds. In addition to its effects on the digestive system, kefir is also of interest because of its ability to support blood pressure control.
Regularly drinking kefir can help reduce systolic blood pressure, which is an index reflecting pressure in arteries when the heart contracts. In some people, this habit also comes with weight loss and waist circumference reduction. Because overweight is associated with high blood pressure, these changes can contribute to improving cardiovascular health.
During fermentation, kefir produces bioactive peptides. Some of these compounds can help blood vessels dilate. When blood vessels dilate, pressure in the lumen of the vessel decreases and blood circulation becomes more favorable, thereby supporting blood pressure stabilization.
Kefir also affects blood pressure through the gut microbiota. Probiotics help balance the microbiota, support regulating mechanisms in the body, including blood pressure. A stable microbiota is related to the activity of the nervous system and blood pressure control signals.
In addition, kefir can help reduce inflammation and oxidative stress. These are factors that can affect the inner lining of blood vessels and increase the risk of high blood pressure. When these factors decrease, blood vessel function is improved, thereby supporting blood pressure control.
Kefir is also related to maintaining nitric oxide levels in the body. This is a substance that helps blood vessels dilate and supports blood circulation. When nitric oxide levels are stable, blood pressure also tends to be more stable.
However, the effectiveness of kefir is not the same in everyone. The level of blood pressure changes may depend on diet, health status, dosage and maintenance time.
Kefir does not replace blood pressure medication. This should only be considered part of a healthy diet. To effectively control blood pressure, it is necessary to combine a balanced diet, regular exercise, and periodic health monitoring.
