Is Indian Food Healthy? What the Science Actually Says

We get asked this question a lot — usually by someone who loves butter chicken but feels a little guilty about it. The honest answer, from a family that has been cooking this food for generations, is more reassuring than you might expect. Strip away the restaurant excess, and authentic North Indian cooking is built on exactly the foundations nutrition scientists keep telling us to eat more of: legumes, vegetables, whole grains, fermented dairy, and an enormous range of spices. The trouble only starts with how some kitchens cook it and how much of it ends up on your plate. Let's walk through what the evidence actually says.

The Foundation: Lentils, Beans and Chickpeas

A traditional Punjabi table is anchored by dal — lentils, in some form, almost every day. This is not a side note nutritionally; it is the headline. According to Harvard's Nutrition Source, legumes are an inexpensive source of plant protein, complex carbohydrates and both soluble and insoluble fiber, and eating them about four times a week is associated with roughly a 14% lower risk of coronary artery disease.¹ In their whole form legumes are low in sodium and saturated fat, a source of folate, and contain slow-digesting resistant starch that helps blunt blood-sugar spikes while acting as a prebiotic for beneficial gut bacteria.¹ Lentils are also particularly rich in polyphenols, plant micronutrients thought to help protect against cardiovascular disease.²

So a bowl of dal, a plate of chana masala, or rajma (kidney beans) is not a guilty pleasure — it is close to a textbook example of what cardiologists recommend. Most of the vegetarian backbone of Indian food sits in this same nutritional sweet spot.

Spices Aren't Just Flavour — Turmeric and the Curcumin Story

The golden colour in nearly every Punjabi curry comes from turmeric, whose active compound is curcumin. This is the single most-studied ingredient in Indian cooking, and the honest picture is "promising but nuanced." A 2023 scoping review of curcumin clinical trials in the International Journal of Molecular Sciences concluded that curcumin "does appear to have biological activity in humans, with significant evidence" of medicinal benefit, with the strongest signals in metabolic and musculoskeletal conditions.³

Two honest caveats matter here. First, results across inflammatory-marker studies are mixed — some meta-analyses find meaningful reductions in markers like CRP and IL-6, others do not.⁴ Second, curcumin is poorly absorbed on its own — though, encouragingly, the body appears able to reform some active curcumin from its circulating metabolites.³ The takeaway: turmeric in your dinner is a genuinely good thing, but it is a flavourful, evidence-backed ingredient — not a medicine.

Yogurt, Raita and the Fermented-Dairy Advantage

Yogurt is everywhere in Punjabi food — in raita, in marinades for tandoori meats, in the lassi at the end of a meal. According to Harvard's Nutrition Source, dairy foods supply protein, calcium and other healthful nutrients, and fermented dairy such as yogurt is lower in lactose and contains gut bacteria that may benefit digestive health; dairy also appears protective against cardiovascular disease compared with similar servings of red meat or refined carbohydrates.⁵ A cooling raita alongside a spiced curry isn't just tradition — it's a gut-friendly habit baked into the cuisine.

The Honest Caveats: Where Indian Food Goes Off the Rails

We promised honesty, so here it is. The healthiness of Indian food at a restaurant depends heavily on a few choices:

• →
  Deep-fried starters.

  Samosas, pakoras and bhajis are delicious but are fried in oil — treat them as an occasional appetiser, not the bulk of the meal.

• →
  Cream and ghee in heavy quantity.

  A splash of cream in butter chicken is authentic; a half-litre poured into the pan to make it "richer" is not. Over-creaming is usually a sign of a kitchen cutting corners on technique, not generosity.

• →
  Restaurant portion sizes.

  A home serving and a restaurant serving are not the same thing. The dish may be balanced; the quantity is what tips it over.

• →
  Sodium.

  The WHO recommends keeping sodium below about 2 grams a day, and most of us already eat more than double that.⁶ Restaurant curries can be salty — but a good Punjabi kitchen carries flavour with the spice blend, so a "less salt" request is easy to honour.

How to Order Indian Food the Healthy Way

None of the caveats above mean you have to skip the food you love. They just mean ordering with a little intention. Build your table around tandoori-grilled proteins — chicken, fish or paneer cooked with dry heat, no added fat — anchored by a dal and a vegetable dish. Choose tandoori roti (whole-wheat, no added fat) over butter naan most of the time, keep the rice portion modest, and add a raita for balance. Then enjoy a shared butter chicken without a second thought. That's not a diet plate — that's just how the food was meant to be eaten. There's also good evidence that this style of eating is genuinely good for the mind, which we explore in your brain on Indian food.
