Zero surprise. RFK Jr et al = hypocrisy machine.

Promise: transparency, good science, & NO conflicts.

Reality: LESS transparency, NO science, & MORE conflicts.

Panel behind new dietary guidelines had financial ties to beef, dairy industries
The industry connections of an advisory panel for the new dietary guidelines are notable, especially in light of Robert F. Kennedy Jr.'s criticism of corporate influence.

2025 was the year protein ‘jumped the shark’ theconversation.com/2025-was-the... by Stuart Phillips 🙏

"Biology is full of plateaus. Protein is no exception."

"More is not endlessly better."

"...no strong, rational, evidence-based case for going beyond [the recommended] range for most people..."
2025 was the year protein ‘jumped the shark’
2025 was not the year protein finally got its due. It was the year protein was oversold, overvalued and overhyped. The science of protein has not changed; we just need to listen to it again.

Canadians have been known to follow the U.S. lead, but @caulfieldtim.bsky.social warns American health policy shouldn't be imported.

He says s new childhood vaccine policy ignores evidence, twists facts, fearmongers about risks, and elevates potential harms.

My first impression: an ideological motivated mess.

A mix of long embraces truisms (more fruits & veggies!), fearmongering, bad advice (more animal protein?), & the oversimplification of complex issues (avoid UPFs).

New dietary guidelines www.statnews.com/2026/01/07/d... via @statnews.com
Dietary guidelines declare war on processed foods and sugar, encourage more protein and dairy
The MAHA movement claims wins — fewer processed foods and seed oils, more beef and dairy products — as Kennedy discards 421 pages of scientific recommendations.

With so many bunk claims, exactly the WRONG move (but totally expected).

MAHA MO: Create barriers & distrust for effective interventions (eg vaccines), but enable wellness industry.

People’s positions on everything from raw milk and miracle supplements to reproductive care, gender, and diet are often shaped by how they vote.

Why are older adults more likely to share misinformation online? Politics. www.digitalinformationworld.com/2026/01/why-...

"...consistently stronger partisanship..."

Age-linked political traits "...reshape what counts as accurate in practice, filtering truth through partisan identity.”
Why are older adults more likely to share misinformation online?
Research shows older adults spot falsehoods yet share more misinformation due to partisan-filtered accuracy.

Such a huge wellness industry push to track health data. Most of it useless & some potentially harmful.

Most frustrating thing about the "can't trust science" arguments – which are usually written & shared via technology made by, um, science – is they provide no alternative.

If not science, what? We'll make bridges & create new health innovations using influencer hot takes?

So much of RFK Jr's MAGA anti-vaxx move deeply problematic.

Science-free, arbitrary, nonsensical, & made without any real expert input.

But the fearmorgering lies might do most damage.

Reality: these vaccines safe, effective, studied, monitored, etc.
