Just did a quick search on kefir and it sounds good...how does the taste actually compare to yogurt?
You might not like it as much as yogurt.
But you can get used to it.
It’s cheap and easy to make your own after you get a culture going.
If you want to buy i really like this goat milk kefir: https://redwoodhill.com/products/plain-kefir/
Kefir has beneficial yeast also, not only bacteria.
And many more good bacteria strain than yogurt.
I eat a lot of high fat plain yogurt and some kefir.
I never buy lowfat or no fat, never with sugar or flavor.
I sometimes add mixed berries
