You might be surprised to see butter on our list of healthy foods, but in moderation, probiotic-rich grassfed butter is full of benefits for your bod. In addition to its high probiotic content, grassfed butter is also high in carotene and vitamin A. And it doesn't hurt that it's creamy, rich, and absolutely delicious — just remember that a little goes a long way!
What to look for: If you want the highest probiotic content possible, go straight to the source, and find local purveyors of raw grassfed butter in your area. However, there are plenty of brands on the market that aren't raw but are grassfed. Kerrygold is easy to find nationwide and not too expensive!
