Always the basics! 👇 Ain't no magic. Exercise, healthy diet, sleep, community... How a top dementia expert keeps his brain healthy www.washingtonpost.com/wellness/202...

Does all the tracking produce "enough meaningful health benefit to justify the cost, effort, and potential for anxiety"❓ Nah‼️ "We should measure success in healthier, happier lives – not more data, more alerts, or more perfect scores." Chill. conscienhealth.org/2026/10/27/d...

One thing that bugs me about all this testing hype – we already over-test. All this data only helps if it, um, actually helps‼️ Does more data always = better health❓ No. Can it lead to harm❓ Yep. Elizabeth Holmes film enthrals — but her legacy haunts science www.nature.com/articles/d41...

Elizabeth Holmes’s Weird Science Finds a New Captive Audience www.nysun.com/article/eliz... Me: “She is clearly a fraud. She exploited people. She hurt science. She is not some misunderstood maverick who was just a bit too enthusiastic.”

‼️ SO many myths about immigrants. ⚠️ Don't believe the hateful lies (looking at you Alberta UCP 👀) Migrants use significantly less NHS care than they effectively pay for, analysis finds www.bmj.com/content/395/... "...pay 60% more towards the NHS than the cost of healthcare they use."

The science & politics behind the panic over ultraprocessed foods theconversation.com/the-science-... "...the very definition of ultraprocessed is highly contested." "...scientists remain unconvinced that processing alone can explain why certain foods are associated with poor health."

⚠️ AI orders more medical tests. A costly pressure‼️ Comparative Cost of Care Recommended by Large Language Models versus Treating Physicians ai.nejm.org/doi/full/10.... "The care these [AI] systems recommended cost substantially more than physicians’ documented care..."

👇 Grim. Disinformation in practice: Threats, actors, mechanisms, and constraints according to those fighting it misinforeview.hks.harvard.edu/article/disi... "Nearly all practitioners expect disinformation to become a greater threat, and only 13% believe institutions will be able to contain it."

Increasingly the word LONGEVITY associated with a product, clinic, influencers, etc = GRIFT! 🚩 LONGEVITY = RED FLAG FOR GRIFT 🚩

How to Lower the Likelihood of Alzheimer’s if You Have a Genetic Risk www.nytimes.com/2026/10/21/w... 👉 Exercise, diet, and community.

This cruel move by Danielle Smith and MAGA UCP❓ It is very obviously about hate, exclusion, and regressive BS that plays to base❗️ Alberta must be better than this! 👎 share.google/MaoUIsZIa2Fe...

📣 Excellent piece...👇 "Hegseth is promoting gender-affirming care for cis men..." "Every relevant medical society recommends against screening asymptomatic men for testosterone deficiency..." Reality: MAGA manosphere BS‼️ Is the Military Low-T? www.newyorker.com/science/anna... #testosterone

‼️ Yet another study deflates supplement hype...👇 Millions take fish oil for brain health. A two-year study found no benefit www.sciencedaily.com/releases/202... "...even when high doses of omega-3s successfully reached the brain, they did not produce measurable improvements..."

‼️ So much hype & myths about icing & heat in exercise.... Reality: not so great.👇 Beyond the ice bath: How heat and cold affect recovery medicalxpress.com/news/2026-10... "...neither heat nor cold resulted in superior recovery of muscle strength over a 72-hour period."

#GoScience‼️ Great results. Gonna be tough for antivaxx cult though... Breakthrough vaccine for the deadliest skin cancer cut risk by almost half wapo.st/4et1aQB #VaccinesWork‼️

🚨 "...found that about 40% of chatbots’ answers to election-related questions contained at least one factual inaccuracy." Sum: Yikes‼️ www.theatlantic.com/technology/2...

"You aren't supporting my science-free grifting the way I expected a Grift Meister to grift support." When the grifters start turning on each other... 👇 www.nbcnews.com/health/healt...

⚠️ Does health misinformation do incredible harm? Yep. ONLY 8% know there is NO credible evidence COVID vaccines increase risk of miscarriage. BIG political divide too (of course). Reality: COVID vaccines improve pregnancy outcomes❗via @kff.org

4 red flags amid the #peptide hype www.usatoday.com/story/life/h... via @usatoday.com Red flag peptide claims: 🚩 Aren't a drug (yes they are❗) 🚩 Safe because natural (not safe, not natural❗) 🚩 Treat illness & heal (NO good clinical evidence❗) 🚩 Can't be patented (of course they can❗)

‼️ Yep, #manosphere a BIG issue...👇 1 in 3 teen boys follows Andrew Tate at least a little, and those who do hold more rigid views of manhood www.psypost.org/one-in-three... From study: "associated with holding beliefs that favor emotional detachment, dominance, toughness, and antifemininity..."

🚨 Continuous Glucose Monitoring in Type 2 Diabetes and Beyond: A Review jamanetwork.com/journals/jam... "CGM should be deployed in response to a specific patient problem rather than as a default intervention." Needed: "...avoiding overuse in populations for whom benefit remains unproven."

📣 Dear Alberta, I'm gonna be blunt... If you voted "yes" to the immigration questions during Alberta referendum, you either: A) Believe the hateful LIES spread by UCP B) Know they are LIES and just leaned into "hateful" part I really REALLY wish there was a rational and less depressing "C"... 💔

DIY healthcare is on the rise – here’s why it’s so dangerous theconversation.com/diy-healthca... So many harms, including: 👉 "...delayed access to professional support." 👉 marketing of unproven products / advice 👉 contaminated, "counterfeit & substandard medicines" 👉 marketing of distrust

Even if AI can improve breast #cancer risk prediction, will that improve patient outcomes? garyschwitzer.substack.com/p/even-if-ai... ⚠️ THE key point: "The trouble is, we don’t know if more accurate cancer risk prediction improves patient-oriented outcomes." "People can get hurt in that process."

‼️ Key: Why I wish you didn’t want to see Nathan Fielder’s Elizabeth Holmes documentary www.statnews.com/2026/10/20/e... by @matthewherper.bsky.social via @statnews.com Documentaries can be powerful (I've produced, written & hosted). But they can manipulate too. She's a fraud. Science hype is bad.

‼️ When misinformation is normalized & politicized THIS happens... There has NEVER been evidence that spacing out vaccines is healthier for children, but this LIE believed by: 👉 69% of Republicans 👉 32% of Democrats #VaccinesWork via @kff.org

📣 Dear Alberta, I'm gonna be blunt... If you voted "yes" to the immigration questions during Alberta referendum, you either: A) Believe the hateful LIES spread by UCP B) Know they are LIES and just leaned into "hateful" part I really REALLY wish there was a rational and less depressing "C"... 💔

Noncitizens don't vote in large numbers in US elections. Here's proof www.snopes.com/articles/474... Reality: "Noncitizens rarely vote in U.S. elections. This is not a partisan opinion." Sad Albertans fell for this lie. All about creating barriers to voting and doubt & rage about immigrants. 👎

Absolutely heartbreaking to see so many Albertans embrace lies and cruel nonsense about immigrants. 💔

So #UCP, lots of money for BS advertising and propaganda stigmatizing immigrants, but not so much for actual voting process? Please vote, #Alberta! 💪 www.cbc.ca/news/canada/...

📣 Dear #UCP, The vote today in #Alberta? What a massive, massive, massive waste of resources and taxpayers' money. What a hate-mongering debacle. What a lie-infused polarizing clusterf*ck. Shame. On. You. 😡

These 4 routine vaccines may also help protect your heart wapo.st/4yx3SMf Shingles vaccine ✅ Annual flu shot ✅ Covid shot ✅ RSV vaccine ✅ #VaccinesWork!

We are gonna hear a lot about Theranos & Holmes. ⚠️ Documentaries are a powerful art form that can also mislead. I haven't seen this doc yet, but...👇 Key: I was a Theranos whistleblower. In ‘You Can See Everything,’ Elizabeth Holmes is still lying www.statnews.com/2026/10/19/e...

Such a blast (and honour) to interview my friend, the amazing and engaging global health scholar, @gavinyamey.bsky.social! 🙏🙏🙏 Does global health equity and justice matter more than MAHA longevity influencer BS? Ummm....

I care. A lot. I don't think that is rational. But I care. I'm working on my next book and I'm not using AI for any of brainstorming, writing, editing, etc. I'm even doing refs old school. An overreaction? Probably. Who Cares Whether Academics Use AI to Write? www.chronicle.com/article/who-...

Don't let the lies win! 💪 YES to Canada. 🇨🇦 NO to NINE. 👎 AI misinformation floods feeds ahead of Monday's vote calgaryjournal.ca/2026/10/18/a... Me: “Unfortunately, you can create very convincing AI content that sort of supports preconceived notions, preconceived lies, about important topics."

With so much BS in the world, refreshing to see some truthful marketing. 👇

The MAGA cult finally dissipating❓ Meantime, UCP pushing Albertans to vote for a hateful, cruel and evidence-free MAGA agenda❓ #Alberta, NO TO THE NINE❗ wapo.st/4inunih

⚠️ Ugh. A very misleading headline: wapo.st/4eCal16 Reality: lots of cancer fearmongering marketing & little evidence of benefit for these early cancer detection products. Sum: “The marketing is ahead of the science" And my friend Arthur Caplan: “modest benefit, high cost, high risk of misuse.”

Yep❗ Health Claims on Food Promote Sales More Than Health conscienhealth.org/2026/10/17/h... "...stop treating selective marketing claims as a reliable guide to healthfulness. Claims should reflect the whole nutritional profile, not just the feature most likely to sell." PS Blue Zone = bogus data

‼️ Conspiracy theories & rage cluster. OF COURSE this separatist conference has: - vendors selling bunk products ($6,500 LED helmets to prevent dementia?) - “anti-woke” rhetoric & grievance about immigrants - sale of gold & silver for when money "fails" Sigh. www.theguardian.com/world/2026/o...
