In 2001, I was battling hypertension and diabetes. It was then that I started drinking kefir and I noticed an interesting occurrence. It seemed that when I drank a glass of kefir every day my blood pressure would go down; and not just a little, but quite a bit. It would put me in the normal range. When I would stop drinking kefir, my blood pressure would start to creep up after three days. So I started doing experiments on myself to see if it was the kefir. After many, many trial runs I was convinced it was the kefir. I have never been one to just accept without knowing the reasoning behind anything, so I began searching for answers.
A couple of months later, I was reading a book called Bacteria For Breakfast which described fermented milk products and how they lower blood pressure in people with mild hypertension. To combat hypertension doctors often prescribe what is known as an ACE-inhibitor, a drug that helps decrease the tension in blood vessels, thus decreasing blood pressure. What the study discussed in Bacteria for Breakfast found is that some strains of probiotic food 1 produce their own ACE-inhibiting substances during the fermentation process.
Kefir and Blood Pressure
ACE-inhibiting substances in kefir
Another study, done in April 2018 2 by Auburn University in collaboration with the University of Vila Velha in Brazil, studied three groups of rats to determine how kefir reduces high blood pressure.
They classified them into three groups.
- The first group had high blood pressure and consumed kefir every day for 9 weeks.
- The second group also had high blood pressure but did not receive kefir
- The third group did not have high blood pressure and they were not given kefir
After nine weeks, the rats who had received kefir had lower levels of endotoxins, lower blood pressure, and improved intestinal permeability. This describes the way materials pass from inside the gastrointestinal tract through the cells lining the gut wall into the rest of the body. The consumption of kefir also restored four different bacteria that were not present in the gut. The microorganisms that populate our guts have been shown to communicate with the brain. Kefir’s effect on gut bacteria appears to reduce the levels of inflammation in the central nervous system and signals the brain to lower blood pressure to healthy levels. 3 According to these researchers, “Our data suggest that kefir antihypertensive-associated mechanisms involve gut microbiota-brain axis communication during hypertension.”

Here is How to Make Kefir.
Here are the two methods for making kefir. You can pick the method that suits you – the benefits are the same in both methods.
