Curd or buttermilk: Which is better for your gut health, hydration, and overall well-being

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. Understanding the difference between curd and buttermilk helps you choose the right one to support your body’s needs, whether it’s for better digestion, hydration, or overall wellness.



Comparing the health benefits of curd and buttermilk
Curd

Curd, or dahi, is a fermented dairy product made by adding a small amount of culture (lactic acid bacteria) to warm milk. This bacterium converts milk sugar (lactose) into lactic acid, which causes the milk to thicken and develop a mildly sour taste.

Traditionally set at home, curd is a natural source of probiotics that support digestion and gut health. It’s thicker, creamier, and more filling than buttermilk, making it a versatile ingredient for both sweet and savoury dishes.


Buttermilk

Buttermilk, or chaas, is the thin, refreshing liquid left behind after churning butter from cream or curd. In modern households, it’s often prepared by whisking curd with water, salt, and digestive spices such as cumin, ginger, and coriander leaves.

Light, tangy, and easy to digest, buttermilk is often considered a natural digestive tonic and summer coolant. It helps restore hydration and supports gut function without the heaviness of milk or curd.



Differentiating between curd and buttermilk: Key parameters explained
When it comes to choosing between curd and buttermilk for specific health goals, each offers unique advantages depending on your body’s needs. Both are rich in probiotics that promote a healthy gut and aid digestion, but their texture, composition, and nutrient balance determine how they support various aspects of health, from weight management to bone strength and hydration. According to a study published in the Journal of Dairy Science, regular consumption of fermented dairy products like curd and buttermilk can significantly improve gut microbiota balance and enhance digestive health . Here’s a closer look at how each fares across different health parameters.


For digestion
Buttermilk is ideal for those who suffer from acidity or bloating. Its light consistency helps flush toxins, and the probiotic bacteria regulate digestion. Curd is also good for the gut but may feel heavy if consumed in excess, especially at night.


For weight loss
If you’re watching calories, buttermilk is your best friend. It delivers the goodness of curd with fewer calories and fat, making it a smart replacement for sugary drinks or milk-based beverages.


For bone health
Curd wins here. It’s packed with calcium and phosphorus, which help maintain bone density and strength, especially important for children, women, and the elderly.


For hydration and cooling

During hot weather, buttermilk outperforms curd. It replenishes fluids, prevents heat strokes, and keeps the digestive system light.


For lactose intolerance
Both are easier to digest than milk, but buttermilk has lower lactose content due to dilution, making it gentler for sensitive individuals.





Traditional and culinary uses of curd and buttermilk

Curd in cooking

Curd is a staple in Indian and Mediterranean cuisines. It’s used in:

• Raita and dips for cooling spicy meals.
• Marinades for meats and paneer, adding tenderness and flavour.
• Desserts like shrikhand or sweet lassi.
• Curries such as kadhi or dahi chicken.

Buttermilk in cooking

Buttermilk’s tangy taste and thin texture make it a versatile ingredient too. It’s used in:

• Kadhi, a popular Indian comfort dish.
• Baking (as in pancakes, scones, or muffins) for lightness and flavour.
• Drinks like masala chaas, a spiced digestive beverage.
• Fermented foods like dosa or idli batter enhance the rise and taste.

Homemade is always better
Store-bought curd and buttermilk often contain preservatives or stabilisers that reduce probiotic value. To get the full benefits:

• Set curd at home using fresh milk and a spoonful of the previous-day curd as a starter.
• Prepare buttermilk by whisking curd with chilled water and adding a pinch of salt, cumin, or mint.
• Homemade versions are richer in live cultures, more digestible, and free from additives.

Which one should you choose: Curd or buttermilk
Both curd and buttermilk are nutritious, probiotic-rich foods that support gut health, immunity, and hydration.

• Choose curd for stronger bones, better gut flora, and a nutrient boost.
• Choose buttermilk for lighter digestion, cooling relief, and hydration.

For a balanced diet, include both curd with your lunch and buttermilk after your meals, to enjoy the best of both worlds.
