Buttermilk (Chaas) for Digestion
Buttermilk (chaas) is a light, cooling probiotic drink that Ayurveda rates more highly than curd itself — easier to digest, gently hydrating, and ideal after a heavy meal.

Buttermilk — chaas in Hindi, takra in Sanskrit — is not a separate product so much as a transformation of one. Curd is churned, the butter is lifted off, and what remains is thinned with water and seasoned with salt and spices.
That process matters more than it appears. Removing the fat and adding water turns something fairly heavy into something notably light. It is the same friendly bacteria as curd, in a form the stomach has far less work to do with — which is precisely why chaas turns up at the end of a large Indian meal rather than at the start.
Traditional Indian buttermilk is also not the cultured buttermilk sold in Western supermarkets. Chaas is churned and diluted; that one is fermented milk, thicker and quite different in taste.
Health Benefits
- ✅ Easier than curd: Diluted and de-fatted, it places less demand on digestion
- ✅ Live cultures: Carries the lactic acid bacteria of curd, supporting gut balance
- ✅ Often tolerable without lactase: Fermentation breaks down much of the lactose, so many people who struggle with milk manage chaas comfortably
- ✅ Cooling in summer: Salted chaas replaces both fluid and sodium lost through sweat
- ✅ Low in fat: The butter has been removed, so it is light on calories
- ✅ Calcium and protein: Contributes both, without the heaviness of full-fat dairy
- ✅ Settles heaviness: Traditionally taken after rich or fried food
Chaas is a supportive daily drink, not a treatment for any digestive condition.
The Ayurvedic View (Takra)
Ayurveda is unusually enthusiastic about takra, and draws a sharp distinction that modern kitchens often blur:
- Curd (dahi) is considered guru — heavy, and capable of aggravating Kapha, especially at night
- Buttermilk (takra) is considered laghu — light, kindling to digestive fire, and far more freely recommended
Rasa (Taste): Amla (Sour), Kashaya (Astringent) Vipaka (Post-digestive): Madhura (Sweet) Dosha Effect: Pacifies Vata and Kapha; well tolerated by most constitutions when properly diluted
Classical texts recommend takra for weak digestion and post-meal heaviness, often spiced with roasted cumin, hing or black salt depending on the complaint. The buttermilk with hing remedy is the everyday version of exactly this idea.
How to Make and Season It
The base: Whisk about one part curd with two to three parts water until smooth and thin. Thicker than that and you are drifting towards lassi.
Common additions:
- 🌿 Roasted cumin powder — the near-universal choice
- 🧂 Black salt — adds savour and a mineral edge
- 🤏 A pinch of hing — for gas and bloating specifically
- 🍃 Mint or coriander leaves — cooling, fresh, good in peak summer
- 🌶️ Grated ginger or green chilli — warming, better in cooler weather
- 🥒 Grated cucumber — turns it into something closer to a light meal
Best Time & Smart Tips
- 🕐 After lunch is the classic slot — it is the meal Ayurveda expects to be largest
- ☀️ Through summer afternoons, salted rather than sweet, for fluid and electrolytes
- 🌙 Avoid late at night — traditional practice discourages fermented dairy after dark
- 🧊 Cool, not ice-cold — very cold drinks are thought to dampen digestive fire
- ⏱️ Make it fresh; chaas separates and sours quickly once it sits
- 🥛 Thin it properly — under-diluted chaas is just runny curd and loses the lightness that is the whole point
Precautions
- ❗ Dairy allergy is different from lactose intolerance — those with a true milk allergy should avoid chaas entirely
- ❗ Colds and congestion: Traditional practice avoids it while these persist
- ❗ Salt intake: Salted chaas adds up if you drink several glasses; those managing blood pressure should account for it
- ❗ Sour stomach: If it aggravates acidity for you, keep it well diluted and skip the black salt
- ⚠️ Fresh, properly diluted chaas after a meal suits most people comfortably
FAQs
Q: What is the difference between chaas and lassi? A: Chaas is thin, usually salted, and made by churning and diluting curd with the butter removed. Lassi is thicker, often sweet, and keeps more of the fat. Chaas is the lighter, more digestive of the two.
Q: Is buttermilk better than curd? A: For digestion, Ayurveda says yes — takra is considered light where curd is heavy. Curd offers more protein and fat per glass; chaas offers the same cultures in a form that sits more easily after a large meal.
Q: Can lactose-intolerant people drink chaas? A: Many can. Fermentation breaks down a good share of the lactose, and dilution reduces it further. Tolerance varies, so start small.
Q: When should I drink buttermilk? A: After lunch is the traditional and most useful time, and through hot afternoons. Traditional practice discourages it late at night.
Q: Does chaas help with weight management? A: It is low in fat and filling, so it is a reasonable substitute for sweeter or heavier drinks. That substitution is where the benefit lies, not in any fat-burning property.
