The EAT-Lancet report shook things up in 2019 by putting food systems at the heart of climate and health. Now it’s back. The 2025 update sharpens the science, adjusts where needed, and adds a crucial layer: social justice.

EAT-Lancet 2025: solid science, but will we bite?
“Scientists say we need to eat less meat!” We’ve all seen headlines like this over the years. And if you saw one recently, it was likely based on the 2025 EAT-Lancet report.

WOW! The European Parliament just voted to BAN the words 'burger' and 'sausage' when used in sustainable plant-based alternatives. HUGE win for the meat and dairy lobby in the EU, and lots more confusion for consumers if this goes through. Insane!

Exactly. Your tofu is not driving deforestation in the Amazon. If anything, eating more soy products directly (and eating fewer animals that eat soy as feed) would *reduce* overall demand for soybeans and pressure on tropical forests.
Soybeans are overwhelming used for feed. 80% of protein produced on Brazil's croplands is used to feed animals iopscience.iop.org/article/10.1....

Good to see another study address land use for various diets.
Funnily enough, the biggest contribution to land use in the "vegan" and "vegetarian" group was still red meat. Meaning actual veg*ns would score a lot better.

The climate trolls are now on Bluesky. Typical troll approach: ask a very leading question that doesn't quite make sense ("IPCC levels" applies to small scale farming in a question ostensibly about methods), fake good-faith engagement, end in total science denial ("ruminants don't belch methane").

Stop worrying about how processed your food is!
Sure, plenty of ultra-processed food is total junk, but it's the old-school stuff that makes it bad: calorie-density, sugar, fat, & sodium.

Column | Why you should worry less about ultra-processed foods
What makes foods so easy to overeat isn’t the level of processing — it’s the density of calories, a.k.a. energy density.
