A reenactment of the well-known 'Evolution of Man' meme with life-sized silhouette cutouts, led by a real person looking at their phone
Evolutionary Association, Chapter 8: Fertiliser

‘Spoiled soil’ is nowhere near the whole story, and fertiliser is nowhere near everything a plant needs.

A gazillion litres of water per burger? Gladly - anything else would be a catastrophe.

Regenerative Agriculture through the lens of International Law

Why global policymakers are turning to managed grazing, and what that means for our plates.

Grains

Grains are among the most fundamental staples - most people can hardly imagine doing without them. Yet depending on whether they are eaten by humans or fed to animals, they are credited with diametrically opposite properties. Schrödinger’s food

antinutrients

Evolutionary Association, Chapter 9: Iodine

Iodine is everywhere and nowhere. It can be absorbed, substituted, or blocked at several stages. What we eat decides which of those happens.

Foods praised for their ingredients often bring the antidote along too. How do antinutrients work? Can they be rendered harmless? A selection.

Sugar - What Exactly Is It?

A long answer to a trivial question - sugar is a great deal more than the stuff sold under that name in the supermarket. And it’s not necessarily sweet

Potatoes with googly eyes watching in horror as another potato is crushed by a potato masher
The Satiety Side Dish

What exactly makes us ‘sated’, and when can we eat again? Is it about volume? Hormones? Nutrients? Answers to rhetorical questions…

How Many Carbohydrates Does the Body Actually Need?

The body needs glucose, but not carbohydrates. A look at the biochemistry shows how it effortlessly sources everything it needs on its own.

Good Carbs, Bad Carbs

The usual split into ‘good’ and ‘bad’ carbohydrates is a convenient shorthand, but my version of that scale looks different: The bar for ‘good’ is higher.
