A Delicious Substitute

 
Although buttermilk’s rich-sounding name and creamy texture suggest
high-fat content, buttermilk is surprisingly low in fat and calories.

Low-fat buttermilk contains only 2.2 grams of fat per cup. This is far
less than the 8 grams contained in whole milk or the 5 grams in 2
percent milk. Consider using buttermilk as a low-fat substitute for
cream in your favorite soup, casserole or dairy-based recipe.
