Here are some of the amazing benefits of buttermilk (chaas).
1. Fights acidity.

If you tend to suffer from acid reflux after a meal, start including chaas in your diet. The yoghurt will cool your stomach and soothe any irritation, while the ginger and spices will help prevent the acidity.
2. Soothes the stomach after a spicy meal.
Spicy food irritates the stomach lining, but chaas can help soothe it. Milk and milk-based products are actually the best remedies for spice – they contain proteins that neutralise the spice and cool off your system.
3. Improves digestion.
The spices in chaas are excellent digestive aids that prevent indigestion and excessive burping. Yoghurt is loaded with probiotics, which encourage the growth of healthy gut flora. This will improve everything from your digestion to your immunity.
