Does Tylenol REALLY Cause Autism?; Health Benefits of Matcha; A Good Brain Health Guide
3 oktober 2025 · 39 min
⚡ The US Government has made waves suggesting Tylenol, aka paracetamol, causes autism. President Donald Trump publicly warned pregnant women to avoid the common pain-killer, even urging them to “tough it out” if they have a fever. But what are they basing this information on? Is there even an ounce of truth in the claim? Lees meer
💬 In a special solo episode of the podcast, I address the Tylenol controversy and explore why Trump’s advice is dangerous for pregnant women. I also look at the growing health trend of matcha tea, and whether its purported benefits line up with the science. Plus I offer a good brain health guide - exploring the factors you can address now to improve your brain and stave off dementia.
🎧 Stay tuned to find out:
➡ Where the autism/Tylenol claim comes from - and why its not reliable
➡︎ How untreated fever poses way more risk to a fetus than Tylenol
➡︎ Which components give Matcha its health benefits - including fiber and antioxidants
➡︎ The type of Matcha you should choose (and what to avoid)
➡︎ The 14 lifestyle factors that improve brain health and reduce dementia risk
