Buttermilk offers significant health benefits including improved gut health from probiotics, strong bone support via high calcium and vitamin content, and hydration with low calories at about 98-110 per cup, but carries risks like digestive distress for lactose-intolerant individuals, high sodium potentially raising blood pressure, and allergic reactions in dairy-sensitive people.
What is Buttermilk?
Buttermilk is a fermented dairy product originally the liquid leftover from churning butter, now mostly cultured milk with added bacteria for tanginess and nutrition. Modern cultured buttermilk dominates markets, providing probiotics unlike traditional versions rare in the West. A 245 ml serving delivers 8g protein, 284mg calcium, and vitamins B12 and riboflavin, making it nutrient-dense at under 100 calories.
Key Nutritional Profile
One cup of low-fat cultured buttermilk contains approximately 110 calories, 9g protein, 3g fat, 13g carbs, and key micronutrients like 30% DV calcium, 25% DV riboflavin, and 22% DV vitamin B12. It's fortified in many brands with vitamin D and A, supporting overall nutrition. Studies from 2019, like those referenced by Healthline, highlight its superior protein-to-calorie ratio compared to milk.
