Curd vs Buttermilk: Uncovering the Unique Health Benefits of Each

When it comes to traditional dairy foods, few can match the refreshing taste and nutritional richness of curd and buttermilk. Both have held a cherished place in Indian diets for generations, known for their cooling effect, probiotic goodness, and digestive benefits.Despite their close connection, as buttermilk is derived from curd, these two dairy staples differ greatly in texture, composition, and health impact. Curd is thicker and richer, packed with calcium and protein, while buttermilk is lighter, hydrating, and ideal for digestion.

It’s thicker, creamier, and more filling than buttermilk, making it a versatile ingredient for both sweet and savoury dishes.ButtermilkButtermilk, or chaas, is the thin, refreshing liquid left behind after churning butter from cream or curd.
