Worth Knowing:
The Question Most Health Headlines Skip: How Much?
By Mark J Kaylor
“Turmeric fights inflammation.” You read it, nod, and shake a little extra into tonight’s curry. It feels like a small, smart choice, and it might be. But there’s a detail the headline left out.
Most of the research behind that claim didn’t use Turmeric the spice. It used curcumin, one compound from the root, concentrated into capsules, often around 1,000 mg a day. Store-bought ground Turmeric runs roughly 1.5 to 3 percent curcumin, so a teaspoon holds about 45 to 90 mg, a small fraction of that.
That doesn’t make the spice in your kitchen pointless. Turmeric has been used daily for thousands of years, as a whole plant, often with fat and Black Pepper. And a handful of small studies using about a teaspoon of whole Turmeric a day have found shifts in inflammation and oxidative stress markers, with a fraction of the curcumin the extract trials use. The whole plant may not follow the same math as its best-known compound.
Dose isn’t the only detail that goes missing. Form matters, as Turmeric shows. So does duration: a benefit seen after twelve weeks of daily use is a different promise from one you’d feel tomorrow. And more isn’t automatically better; some things help at one amount and cause trouble at another.
So when a claim catches your eye, ask: how much, in what form, and for how long?
Five hundred years ago, Paracelsus put it simply: the dose makes the poison. It also makes the medicine.
