Buttermilk is lower in fat than regular milk, because the fat has been removed to make butter. It is also high in potassium, vitamin B12, calcium, and riboflavin as well as a good source of phosphorus.

Those with digestive problems are often advised to drink buttermilk rather than milk, as it is more quickly digested. Buttermilk has more lactic acid than skim milk.

Now buttermilk is made by adding cultured bacteria to low-fat or fat-free milk, just like yogurt. The live cultures provide its distinctive rich, creamy texture–and a host of health benefits.

Hence drink buttermilk for better health!!!
