Turmeric
Overview
Why use turmeric?
Turmeric is the golden spice behind curry powder, valued for curcumin, the compound that gives it colour and most of its research interest. Because you use it a teaspoon at a time, it adds little in the way of calories or nutrients, but it brings flavour, colour and plant compounds to everyday cooking.
Good to know: Curcumin is poorly absorbed on its own, so pair turmeric with a little fat and black pepper; concentrated supplements can also interact with blood thinners, which is worth raising with a doctor.
Iron in every pinch
Turmeric is remarkably iron-dense at 55 mg per 100 g, and even a 3 g teaspoon supplies 1.65 mg, about 9% of the Daily Value, supporting oxygen transport in blood.
Curcumin and antioxidants
Curcumin, the pigment that makes turmeric yellow, is studied for antioxidant and anti-inflammatory activity, though most research uses concentrated extracts rather than culinary amounts.
Trace minerals and potassium
Per 100 g turmeric provides 2080 mg potassium (44% DV), 208 mg magnesium (50% DV) and 1.3 mg copper (144% DV), minerals involved in blood pressure, nerves and energy metabolism.
