Fermented dairy is one of the most cost-effective gut investments available and one of the most consistently underused.
Plain kefir contains 30 to 56 different bacterial and yeast strains, more diversity than most probiotic supplements. It is also fermented in a matrix that protects bacteria through digestion, so more of them actually reach the colon.
What to look for when buying kefir:
- Full fat, not low fat or fat free
- Plain, not flavored
- Live and active cultures on the label
- No added sugar or thickeners
- Ideally from grass-fed or organic dairy
