Rates of dementia, depression, and autism are climbing, and Dr. Michael Crawford believes it might be because of one missing nutrient in our modern diet: DHA, an omega-3 fat found mostly in seafood.

He's a 97-year-old brain scientist who has spent 50+ years researching the importance of DHA (seafood) for the brain and how the brain won’t work without it. I recently released a podcast episode with him. This post is the companion to the episode: every key idea explained simply, and what to actually do with it.

In This Bonus Takeaways, I Cover:

  1. Why it was DHA, not DNA, that built the human brain

  2. Why DHA is just as critical for your vision as your brain

  3. Why ARA (omega-6) is critical for the brain too, and why it’s wrongly demonized

  4. Why ARA is critical in pregnancy

  5. Why your body can barely make DHA and ARA from their plant precursors, and what to eat instead

  6. Why the official advice to limit fish in pregnancy may be harming babies

  7. How seed oils crowd DHA out of your brain, and why they barely existed before WWII

  8. Why blindly avoiding saturated fat may be a mistake

  9. What a 97-year-old brain scientist actually eats

  10. Why grain-fed chicken lost 90% of its brain fat (DHA)

  11. Why a fish oil capsule will never replace real fish

  12. The theory that your brain runs on light, with DHA as a semiconductor

These conversations are dense with insight, and pulling out what matters most takes real time. That’s why I do it for you. In these bonus takeaways, I pull out the most important ideas from each episode, explain the science in plain language, and turn it into clear, practical steps you can use right away. 10 minutes spent reading these will leave you smarter about how your body works, and practical steps to improve your health starting today.

Paid subscribers get these takeaways for every episode, my own daily protocols, and direct email access to me. If you want to actually use what these scientists are sharing, become a paid subscriber.
