Paneer or tofu: the protein comparison in full

Both are pressed curds. One is made from milk, the other from soy milk. That single difference produces a substantial gap in calories and a smaller one in protein.

The numbers

Food	Serving	kcal	Protein (g)	Carbs (g)	Fat (g)
Paneer, buffalo milk	100 g	296	18.3	2	24
Paneer, cow milk	100 g	258	18.9	2.5	20
Paneer, low fat	100 g	196	20	3	12
Tofu, firm	100 g	144	15.5	3	8.7
Tofu, extra firm	100 g	165	19	2.5	10
Tofu, silken	100 g	62	6.5	2	3.5

Calories per gram of protein

This is the number that decides it for anyone with a calorie target.

• Tofu, firm: 9.3 kcal per gram of protein
• Tofu, extra firm: 8.7
• Paneer, low fat: 9.8
• Paneer, cow milk: 13.7
• Paneer, buffalo milk: 16.2

Firm tofu and low-fat paneer are effectively tied. Full-fat paneer costs nearly twice as much per gram of protein, which is worth knowing and is not a reason to avoid it — it is a reason to weigh it.

For reference, chicken breast is around 5.2 and low-fat curd is 9.7. The full ranking is in vegetarian protein worth the calories it costs.

Micronutrients

Paneer is a strong calcium source, supplying a large share of a day's requirement in 100 g, plus vitamin B12, which is significant for vegetarians.

Tofu set with calcium sulphate is also a good calcium source; set with nigari it is not, and the label rarely says. Tofu carries more iron and no cholesterol, and soy provides isoflavones.

Neither is nutritionally deficient. Both are complete proteins, which puts them in a small group among vegetarian foods — see complete protein.

The saturated fat question

Paneer's fat is largely saturated. Tofu's is largely unsaturated. Cardiovascular guidance generally favours the latter.

For someone eating 100 g of paneer a few times a week inside an otherwise sensible diet, this is a minor consideration. For someone eating 200 g daily it becomes worth attention, alongside the ghee already in the food, which is discussed in dietary fat: the minimum, and why it has one.

Cooking and taste

This is where paneer usually wins in practice, and practice is what determines whether anyone hits a protein target.

Paneer holds its shape, browns well, and tastes familiar to anyone raised on it. Tofu needs pressing to remove water, takes on flavour rather than providing it, and has a texture that some people never come to like.

Firm or extra-firm tofu, pressed for twenty minutes and marinated, works well in Indian gravies and in tikka preparations. Silken tofu is a different product for a different purpose and should not be substituted into a sabzi.

What each dish does to the number

Neither food is eaten plain. The preparation usually matters more than the choice.

• 100 g paneer, grilled tikka style: about 240 kcal
• 100 g paneer in a butter masala gravy: about 450 kcal
• 100 g tofu, stir fried in a teaspoon of oil: about 190 kcal
• 100 g tofu in a cream gravy: about 380 kcal

The gravy is worth more than the protein choice, which is the recurring lesson in how much oil is actually in your curry and the reason calories in paneer spends more time on gravies than on paneer.

Availability in India

Good tofu is not universally available, and the quality varies more than paneer's does. Soya chunks are, and they are more efficient than either at 52 g of protein per 100 g dry.

For most Indian vegetarians the practical answer is: use low-fat paneer as the default, soya chunks when you need protein cheaply, and tofu if you like it and can get a firm one.

The verdict

If you are in a deficit and counting: tofu or low-fat paneer.

If you are at maintenance and eating reasonable portions: whichever you prefer, weighed rather than estimated, because paneer is dense enough that eyeballing costs 100 kcal easily.

The target that all of this feeds is set in how much protein do you actually need per day.
