Curd (dahi) and yogurt are often considered the same, but they are actually quite different in terms of preparation, bacterial composition, and health benefits. Both are fermented dairy products rich in probiotics that support gut health, digestion, and immunity—but the way they are made makes all the difference.
What is Curd and Yogurt?
Curd (Dahi)
Curd is a traditional Indian dairy product made by fermenting milk using a small amount of previously prepared curd as a starter. It is commonly prepared at home and has a slightly tangy taste with a thick and creamy texture.
Yogurt
Yogurt is made using specific bacterial cultures under controlled conditions. It has a smoother, more consistent texture and is widely available in packaged forms, including flavored varieties.

Key Difference: Bacterial Strains
The biggest difference between curd and yogurt lies in the type of bacteria used during fermentation.
- Curd: Made using naturally occurring Lactobacillus bacteria from a previous batch. The bacterial composition may vary from one household to another.
- Yogurt: Contains standardised bacterial strains like Lactobacillus bulgaricus and Streptococcus thermophilus, ensuring consistency in taste and quality.
Because yogurt is made in controlled conditions, it usually has a more consistent probiotic content, while curd may have a wider variety of beneficial bacteria.
Difference in Preparation Method
How Curd is Made
- Milk is boiled and then cooled slightly
- A small amount of curd is added as a starter
- The mixture is kept in a warm place for 6–8 hours
How Yogurt is Made
- Milk is pasteurised
- Specific bacterial cultures are added
- It is fermented at a controlled temperature for uniform results

Which is Better for Health?
Both curd and yogurt offer excellent health benefits, but their advantages differ slightly:
For Protein
- Yogurt, especially Greek yogurt, usually contains more protein due to its concentrated form
For Digestion
- Curd is ideal for daily gut health as it contains a variety of natural bacteria that help digestion
For Lactose Intolerance
- Yogurt is often easier to digest because its bacterial strains break down lactose more efficiently
Final Verdict
There is no clear winner between curd and yogurt. Both are healthy and beneficial for digestion and overall well-being.
- Choose curd for traditional nutrition and diverse probiotics
- Choose yogurt for consistency, convenience, and higher protein options
Including either in your daily diet can significantly improve gut health and immunity.
