Did you know.......

....buttermilk is lower in fat and calories than regular milk?!  You wouldn't think that by the looks of it!

Here's what Wikipedia says:

Benefits

Cultured buttermilk is lower in fat and calories than regular milk because the fat from buttermilk has already been removed to make butter. It is high in potassium, vitamin B12 and calcium. Buttermilk is more easily digestible than whole milk and it also contains more lactic acid than skim milk. Due to being more easily digestible (a result of the bacteria added to the milk), protein and calcium can be taken up more easily by the body. There are 99 kilocalories and 2.2 grams of fat in one cup of buttermilk (fat content may be different with some buttermilk brands, as some brands are made with skim milk while others are made with reduced fat milk), as opposed to whole milk that has 157 kilocalories and 8.9 grams of fat.

I'm going to use buttermilk in everything!  Well, not everything, but you know what I mean :)
I'm going to make buttermilk biscuits  soon.....mmmmmm
