I never heard of kefir. Just looked it up. Do you make it or buy it? I do eat yogurt at least 3 times a week.
Plain Greek yogurt, fruit, flaxseed, brewer’s yeast and lots of walnuts.
Lifeway is the brand sold in all the stores around here. If its not in the regular dairy section at your grocer it may be in a special organic/healthfood area.
I like the blueberry and raspberry the best. Pretty much all of the rest of the flavors are pretty good except for the chocolate and birthday cake which are quite hideous.
The carb rating per serving can make it difficult to justify for those on a low carb/no carb diet.
As Gnarledmaw stated, Lifeway is a great brand of kefir. They come in quart size. Besides all the stuff that is good for your gut, it has 40 grams of protein in each quart. Other brands will probably also be good. Enjoy!
