Turmeric

Overview
Turmeric is the whole spice (dried and ground root of the Curcuma longa plant) that contains many bioactive compounds, including curcumin (the most well-known polyphenol), demethoxycurcumin, bisdemethoxycurcumin, turmerones (fat-soluble compounds), and essential oils. Only 2–6% of turmeric powder is curcumin. Curcumin is responsible for most of turmeric's anti-inflammatory and neuroprotective effects.
Within the BRAIN Diet framework, absorption is enhanced by pairing with black pepper (piperine) and fat. Therapeutic doses typically use 500–1000 mg/day curcumin with piperine [1][2].
Key Nutritional Highlights

Food Context
Synergies
- Pair with black pepper (piperine) for up to 2000% increased bioavailability
- Pair with fat and heat for enhanced absorption
- Part of culinary spice strategy
Preparation
- Can be used in therapeutic doses when needed
Essential Amino Acid Profile
Turmeric contribute plant protein. Pair with complementary protein sources (e.g. grains and legumes) for a balanced essential amino acid profile.

| Compound / class | Amount per 100 g | Notes |
|---|---|---|
| Curcumin | 3500 mg * | Curcuminoids are often ~2–6% of turmeric powder; piperine + fat improves absorption. |
