Ghee, turmeric, and what the evidence actually supports

Indian food culture carries a lot of health claims, and they arrive from two directions at once. One says ghee is a superfood and turmeric cures inflammation. The other says ghee is saturated fat and will block your arteries.

Both are overstatements. The useful position is in between, and it is less satisfying than either.

Ghee

What it is. Clarified butter — milk fat with the water and milk solids removed. Around 60% saturated fat, with some short- and medium-chain fatty acids, small amounts of butyrate, and fat-soluble vitamins A, D, E and K.

What the enthusiasts claim. That it is uniquely healthy, aids digestion, and is exempt from the usual concerns about saturated fat because it is traditional.

What the critics claim. That it is straightforwardly bad and should be eliminated.

What is reasonable. Ghee is a cooking fat with a high smoke point, which genuinely matters for Indian cooking — it is stable at tadka temperatures where many seed oils are not. It is also calorie-dense at about 9 kcal per gram and predominantly saturated.

The relevant evidence is not about ghee specifically; it is about what you replace with what. The strongest cardiovascular dietary trial we have, PREDIMED, found benefit from a Mediterranean pattern high in extra-virgin olive oil and nuts — a pattern dominated by monounsaturated fat.

That does not make ghee poison. It makes it a fat to use in the amounts your grandmother used it in — a spoon, not a ladle — rather than one to add enthusiastically because the internet reclassified it as a superfood.

A teaspoon or two a day in cooking is a normal part of a good diet. Ghee coffee is marketing.

Turmeric

What it is. A spice whose principal active compound is curcumin, which has genuine anti-inflammatory and antioxidant activity in laboratory conditions.

The problem. Curcumin is poorly absorbed. Oral bioavailability is very low — it is rapidly metabolised and cleared, and reaching meaningful blood concentrations from food is difficult. This is why supplement formulations add piperine from black pepper, or use liposomal and phytosomal preparations, to raise absorption.

Where the evidence stands. There is a large volume of published work on curcumin and a much smaller volume of high-quality human trials. Some show modest benefit for joint pain — comparable in a few trials to over-the-counter anti-inflammatories. Many are small, short, and industry-funded. The distance between "shows activity in a dish" and "changes an outcome in a person" is where most of the excitement lives.

What is reasonable. Turmeric in your food is good. It is a pleasant, ancient, harmless part of the cuisine and there is no reason to change anything.

Turmeric as a supplement for a specific condition is a different question, and the honest answer is that the evidence is suggestive rather than established. If you take it for joint pain and it helps you, that is a legitimate reason to continue. It is not a substitute for loading the joint, which has considerably better evidence behind it.

The pattern behind both

Notice what happened in each case. A real ingredient with some real properties gets amplified into a claim that the evidence does not carry, and then a backlash overcorrects in the opposite direction.

The useful filter is a question: what is this replacing?

Ghee instead of vanaspati is an improvement. Ghee in addition to everything else you already eat is extra calories. Turmeric in your dal is good food. Turmeric capsules instead of training your knee is a substitution that will not work.

No single ingredient is going to move your health meaningfully in either direction. The things that do — enough protein, enough load on your skeleton, enough cardiovascular work, enough sleep — are boring, well-evidenced, and much harder to sell.
