May be helpful in cancer treatment

Some test tube studies have shown that kefir can inhibit the growth of cancer cells.

How does kefir act against cancer?

The probiotics present in kefir can reduce the formation of carcinogenic compounds and thus inhibit the growth of tumors.

According to one study, kefir extract reduced the number of breast cancer cells by 56%, compared to 14% for yogurt extract.

However, studies in humans still need to be carried out to determine if kefir is really effective against cancer.
