An American study: Intermittent fasting helps reduce high blood pressure

Intermittent fasting has been shown to have many health benefits, from aiding weight loss to reducing the risk of type 2 diabetes and improving brain function, and a research team at Baylor College of Medicine in the US has shown that intermittent fasting can reduce high blood pressure. By reconfiguring the gut microbiome using an animal model, evidence suggests that disruption of the gut microbiota can have adverse effects on blood pressure.

High blood pressure is a common condition that can increase the risk of heart disease, stroke, and sometimes death. The researchers noted, according to the report of the site "thehealthsite" that nearly half of adults in the United States suffer from high blood pressure, which increases the risk of two major causes of death in the United States (ie, heart disease and stroke).

What is intermittent fasting?

Intermittent fasting is an eating pattern that switches between fasting periods with no food or significantly reducing calories and eating periods, and there are many methods for intermittent fasting, from fasting for 16 hours to alternate day fasting and fasting for two days a week.

Intermittent fasting lowers blood pressure

To see if manipulating gut microbes could regulate blood pressure, the American team created two groups of mice, one group that had spontaneous hypertension and the other normal that were fed every day.

After 9 weeks, the researchers noticed that the mice with automatic blood pressure and who fasted day after day (intermittent fasting) had significantly lowered blood pressure compared to the mice that did not fast.

Moreover, they observed that the germ-free mice that received microbiota from the fasting spontaneous hypertension mice had significantly lower blood pressure than the other mice.

Overall, this study provides evidence that changes in the gut microbiota contribute to elevated blood pressure by altering bile acid signaling, and also indicates that intermittent fasting could be beneficial in reducing hypertension by reconfiguring the gut microbiota composition.
