Haven't tried buttermilk? It's time you gave this old-fashioned staple a chance.

Buttermilk is packed with health-promoting probiotics including Lactococcus lactic and Leuconostoc cremoris that provide a myriad of benefits ranging from gastrointestinal health to cancer prevention.

Delicious whirled into a smoothie and wonderful for baking, buttermilk lends a rich, hearty flavor with fewer calories than whole milk or cream. It's also a great base for creating soups or salad dressings. Because of its high acidity, buttermilk makes an effective and flavorful marinade.

As with all dairy products, choose organic buttermilk (preferably from grass-fed cows) that is rBGH-free.
