I just read all 90 pages of the 2025-2030 Dietary Guidelines, and I will apologize for the length and wonkiness of my take on it.

This is pretty detailed, and you may not have the stomach or patience for it, but here goes.

A very long 🧵

"...the approach is little more than a gish gallop to support the preformed conclusions that the HHS Secretary, MAHA advocates and influencers have been pushing since the moment they got into office."

Excellent breakdown of the new US dietary guidelines.

The new US Dietary Guidelines ignore recommendations made by scientists around the benefits of plant protein.

Big win for the meat/dairy sector, bad news for health and our environment.

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.

Our breakdown of the report. 👇
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!

Bye bye veggie burgers?

Ridiculous government overreach and policing of language, all thanks to the meat lobby.

Please sign and share this, particularly if you're a European citizen. What Brussels is proposing is both damaging and incredibly dumb, and the European Parliament is about to vote (on 8 October) on an amendment to make it even worse! Please do sign 🙏

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....
The recent tariff issue is a prime example of how the world's taste for meat (not soy) is shaping distant landscapes. www.theguardian.com/global-devel...
How the world’s taste for soya is eating Brazil’s Amazon
Cultivation of the crop has made a few wealthy but at a huge cost to untouched forest as it spreads across vast areas of former wilderness

Meat vs EAT-Lancet - 🥩🌱 - interesting report.

Expecting another massive anti EAT-Lancet campaign when the 2025 update drops next week.

Sterke tekst over hoe een moderne groene partij zich zou moeten positioneren.

Hopelijk gaan we dit terug zien in de praktijk. 🤞
Dit academiejaar werd ik als non-academic mentor gekoppeld aan Ebru Akgün een doctoraatsstudent van UAntwerpen / VUB.

Deze boeiende uitwisseling leidde tot een tekst over hoe het #ecologisme meer mensen kan meekrijgen in de #klimaattransitie

Dank @sampolmaandblad.bsky.social om te publiceren!
Hoe het ecologisme meer mensen kan aanspreken
Groene partijen staan vandaag vooral in de verdediging. Het is tijd om het klimaatverhaal te herschrijven, zodat meer mensen de noodzakelijke klimaattransitie steunen.

Billions of animals are tortured for meat each year. Millions of slaughterhouse workers suffer too -- physically and mentally: www.vox.com/future-perfe...

This quote really stands out: “Public demand for meat creates ongoing, present, and future exposure to trauma and continual retraumatization.”

"If we killed every deer in the UK, it could maybe supply 1% of our meat consumption — or three days’ worth of meat."

Unmasking bad ideas around sustainable food production is often easy - just ask the question:

"How does it scale?"

I'm seeing a lot of "Ultra-processed food increases risk of early death" headlines again.

Did you know that UPF consumption also has a positive association with accidental deaths?

The Keto-CTA paper brouhaha is small potatoes compared to a crumbling democracy, but it demonstrates how people believe wrong stuff.

Cherry pick evidence
Manipulate data
Hang out in your silo
Trust your gut

That's how we get RFK Jr, as well as folks who think high LDL is OK as long as it's keto.

In this one, plant protein was more reliably associated with a reduction in frailty.

Highly recommend reading this piece. The pseudoscience around sustainable fishing is quite shocking, and doesn't get much attention.

Also, follow Spencer.
We have been lied to by the fishing industry.

I believe this is one of the great scandals of our age, comparable to oil corporations’ denial of climate change.

Global fishing regulations are based on a pseudoscience contrived to justify cutting the world’s fish populations in half.

Fishing sustainability is based on a pseudoscientific theory that justifies taking the most marine life for maximum profit.

I hate this trope among writers who write about this issue of explicitly saying they feel guilty for the thing they nonetheless do. You're a rich, informed American surrounded by abundant, accessible food who writes about this for a living. You CAN easily not do the bad thing and write about THAT.

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").

People working on sustainable agriculture/diets often get accused of having a hidden plant-based agenda. 🌱

Apparently the livestock industry was already using this argument in 1989. 🥩
