WHAT IT’S REALLY ABOUT
Food pairings that boost nutrient absorption and blunt benefits
- Heating tomatoes and cooking them with fat (like olive oil) converts lycopene into a more absorbable form and improves uptake dramatically.
- Pairing fat-soluble plant compounds with healthy fats (e.g., avocado with cooked tomatoes) increases nutrient absorption and may amplify health effects tied to those compounds.
- Some combinations can reduce benefits, such as adding cow’s milk to tea, where dairy fat micelles can trap tea polyphenols (catechins) and lower absorption.
- Black pepper (piperine) paired with turmeric increases the body’s retention/absorption of curcumin, enhancing turmeric’s potential effects.
- Supplements are framed as add-ons rather than replacements for whole foods, with omega-3s and vitamin D3 highlighted as practical, high-value examples for many people.
IDEAS WORTH REMEMBERING
5 ideasCooked tomatoes deliver far more usable lycopene than raw.
Li states raw tomato lycopene is poorly absorbed (~20%), but heating changes its chemical structure so absorption can rise to ~80%.
Add a little healthy fat to access fat-soluble plant compounds.
Because lycopene is fat-soluble, sautéing tomatoes in olive oil helps carry lycopene into the body more efficiently than cooking in water.
Common snacks can be “functional” nutrient pairings.
He uses salsa (cooked tomatoes) plus guacamole (avocado fats) as an example of a real-world combo that boosts lycopene uptake.
Turmeric works better when paired with black pepper.
Curcumin has many touted benefits but is poorly retained; piperine from fresh cracked black pepper helps the body “hang on” to curcumin for greater absorption.
Milk in tea may reduce polyphenol benefits even if it tastes great.
Cow dairy fat can form micelles that trap tea catechins (like EGCG), lowering their absorption and potentially reducing desired effects (stress-lowering, anti-inflammatory, metabolic and anticancer-related properties mentioned).
WORDS WORTH SAVING
5 quotesI've studied lycopene in a laboratory, and it actually can help starve cancers by cutting off the blood supply.
— Dr. William Li
If you wanted to convert that chemical structure of lycopene into a form that you can absorb better, your body can avidly absorb, what you wanna do is you wanna heat the tomato, like in a pan.
— Dr. William Li
So if you have fresh cracked black pepper with your turmeric, uh, you a- you're actually creating a one-two punch that allows you to absorb more of the curcumin.
— Dr. William Li
When milk or cream is put into tea, the fat molecules in the cow dairy form little soap bubbles. These are microscopic soap bubbles. They're called micelles.
— Dr. William Li
Those soap bubbles trap the polyphenols from tea. It traps the catechin.
