Turmeric root has 312 kcal per 100 g, used in grams per recipe. The active compound curcumin has low bioavailability on its own — combining with black pepper (piperine) increases absorption by ~2,000% (Shoba et al., Planta Med 1998). Culinary amounts are macro-negligible.
How should I track Turmeric root?
Turmeric root is high in iron. The most reliable way to track Turmeric root is with a kitchen scale. Studies show that visual estimation is off by 20–50% on average (Almiron-Roig et al., Appetite 2013). A quick weigh takes seconds and removes the guesswork from your daily logging. If you are unsure, log slightly more rather than less — research (Wehling & Lusher, Am J Clin Nutr 2021) shows underreporting is the most common calorie tracking error, with people reporting 25–30% less than they actually eat.
