Use herbs and spices liberally as low-calorie polyphenol sources

Herbs and spices have among the highest polyphenol density of any food — gram for gram, more than berries or vegetables.

Why it works

Turmeric (curcumin), ginger (gingerols), rosemary (rosmarinic acid), oregano (carvacrol), and cinnamon all contain polyphenols that modulate NF-kB, the master transcription factor for inflammatory gene expression. These are small absolute contributions to polyphenol intake but are additive — liberally spiced food across every meal contributes a meaningful daily anti-inflammatory load without requiring any change in food volume.

How to do it

1. Add turmeric to scrambled eggs, soups, or rice; combine with black pepper (piperine) to increase curcumin absorption by up to 20x.
2. Use fresh or dried ginger in teas, stir-fries, and dressings.
3. Use fresh herbs (parsley, basil, cilantro) as vegetable-sized additions, not garnishes.
4. View spices as functional food, not just flavoring — the dose is higher than you probably use.

Evidence

Individual spice polyphenols (curcumin, gingerols) show anti-inflammatory activity in cell studies and small trials; whole-diet effects of spice use are observational and indirect. (mechanistic)

Most curcumin trials use high-dose supplements with enhanced bioavailability; dietary turmeric at cooking doses delivers lower curcumin than studied doses. Benefits from culinary use are real but smaller.

Common mistake

Buying a curcumin supplement expecting concentrated anti-inflammatory benefit, while overlooking that a diet full of herbs and spices across every meal achieves similar cumulative polyphenol exposure.
