Claim: ‘Contains billions of live cultures, kefir is also high in protein and a source of vitamin B12. Reduced sugar.’
Expert verdict: Kefir [fermented milk] contains a variety of bacterial cultures and yeasts good for gut health and the immune system and is a good source of calcium, and while the evidence about just how many of these survive when kefir is frozen is scant, you should get a useful amount from this.
There’s a good portion of protein here 4.2g in a two-scoop serving, approximately a small egg’s worth.
