Curd (dahi) is milk that has been fermented by lactic acid bacteria. The bacteria turn some of the milk sugar (lactose) into lactic acid, which thickens the milk and gives curd its tang. Nutritionally the two are close — but there are differences worth knowing.
Curd vs milk per 100 g
Milk from IFCT 2017 (whole cow milk); curd and hung curd are typical values for curd made from whole milk and thick strained curd, which vary with the milk used.
| Per 100 g | Whole cow milk | Curd (whole milk) | Hung curd / Greek yogurt |
|---|---|---|---|
| Calories | 73 kcal | ≈ 60–65 kcal | ≈ 90–110 kcal |
| Protein | 3.3 g | ≈ 3.1 g | ≈ 8–10 g |
| Fat | 4.5 g | ≈ 3–4 g | ≈ 4–5 g (less if made from toned milk) |
| Carbohydrates (mostly lactose) | 4.9 g | ≈ 3–4 g | ≈ 3–4 g |
| Calcium | ≈ 120 mg | ≈ 120–150 mg | ≈ 100–150 mg |
Per typical serving
| Serving | Calories | Protein |
|---|---|---|
| Milk, 1 glass (200 ml) | ≈ 146 kcal | ≈ 6.5 g |
| Curd, 1 katori (150 g) | ≈ 90 kcal | ≈ 4.7 g |
| Hung curd, 150 g | ≈ 150 kcal | ≈ 13 g |
| Buffalo milk, 1 glass (200 ml) | ≈ 214 kcal | ≈ 7.4 g |
Digestion and lactose
Fermentation breaks down part of the lactose, and the live bacteria in curd help digest some of the rest. That is why many people who feel bloated after milk are comfortable with curd, buttermilk or hung curd. If milk does not bother you, there is no need to avoid it.
Probiotics
Curd with live cultures contains bacteria such as Lactobacillus that may support gut health. The evidence for specific health benefits varies by strain and person, so think of curd as a helpful everyday food rather than a medicine. Heating curd (for example in kadhi) kills the bacteria but keeps the protein and calcium.
Which is better for your goal?
| Goal | Better choice | Why |
|---|---|---|
| Weight loss | Curd or hung curd from toned milk | Filling, lower calories per serving, easy to pair with meals |
| Muscle gain | Milk (and hung curd) | Easy extra calories and protein in a glass; hung curd for dense protein |
| Most protein per serving | Hung curd / Greek yogurt | About three times the protein of regular curd |
| Lactose sensitivity | Curd, buttermilk, hung curd | Less lactose and better tolerated |
| Bone health | Either | Both are good calcium sources |
Easy ways to use both
- A glass of milk or milky tea with breakfast; curd with lunch and dinner.
- Raita or buttermilk instead of sugary drinks.
- Hung curd with fruit as a high-protein snack — more ideas in high-protein vegetarian Indian breakfasts.
- Milk with oats or dalia for a filling porridge.
- Curd-based marinades for paneer, tofu or chicken tikka.

Key takeaways
- Curd and milk have similar protein and calcium per 100 g.
- Curd is easier for many lactose-sensitive people and contains live cultures.
- Hung curd has about three times the protein of regular curd.
- Milk suits bulking; curd and hung curd suit weight loss and high-protein snacks.
