Plant compounds: how the score counts polyphenols and co.

AI-generated image: Freshly washed blueberries, blackberries and raspberries in a metal colander by the sink, water droplets, a few berries on the counter

Our plant compounds score counts how many different groups of plant compounds a recipe contains – from berries and cocoa to cabbage, herbs and citrus.

What the plant compounds score measures

Plants contain thousands of compounds that give them their colour, smell and bitterness – polyphenols in berries, cocoa and tea, carotenoids in carrots and tomatoes, glucosinolates in cabbage. Our score – shown on each recipe as “Plant compounds” – counts how many different groups of them a recipe contains.

Variety counts more than a single “top” ingredient: four groups give an extra point, six give two. For recipes at the top of the scale, see recipes with lots of plant compounds.

How we score it

Every recipe starts at 3. Three kinds from one group give +1 extra. Tiny amounts only count for spices, herbs and seaweed.

The score doesn’t measure how much of it your body takes up.

The score follows fixed rules, the same for every recipe. It doesn’t replace medical or dietary advice.

Frequently asked questions

Why don’t you use ORAC values?

ORAC measures antioxidant capacity in a test tube. It says nothing about what happens in the body – that’s why the US Department of Agriculture withdrew its ORAC table in 2012. Variety is the more robust measure.

What are polyphenols?

A large group of plant compounds, found for example in berries, cocoa, tea, coffee, olive oil, herbs and many vegetables. They give plants colour and bitterness. Our score counts them by food group, not by milligram.
