Buttermilk is an excellent source of protein, which your body needs to build healthy muscles, skin, and bones. It may also aid in digestion and help clear your stomach because of the acid in it. Regular consumption of buttermilk helps reduce the onset of several stomach ailments like irritable bowel syndrome, stomach infections, irregular bowel movements, lactose intolerance, and colon cancer.
If you have trouble digesting regular milk you may want to try buttermilk instead. It contains many of the same nutrients but is easier to digest, because of the lactic acid bacteria feed on lactose, a kind of sugar in milk that makes some people sick.
Buttermilk is simply the milk that occurs when the cream is churned into butter. It is a great product to marinate meats with, make delicious pancakes, and lots of other great baked goods!
