Ep.7 Blueberries, Coconut Oil, and the Mediterranean Diet: What the Nutrition Research Actually Says

Someone told me to give my mom coconut oil after her Alzheimer's diagnosis. My mom couldn't remember I was pregnant at the time. The person meant well. The advice was wrong. And for someone with APOE4 genetics — which both my mom and I carry — it wasn't just wrong. It was potentially the opposite of what the research supports.That moment is where this episode starts. Because the problem isn't people giving bad advice. The problem is an information ecosystem built to capture attention rather than convey evidence. Confident nutrition claims travel faster than careful ones, and for APOE4 carriers specifically, some of what's circulating online isn't just unhelpful, it's working against you.This is the third and final episode in the Race Against Mind nutrition series. Episodes 5 and 6 covered the personal cholesterol arc and the APOE4 lipid mechanism. This episode covers the broader nutrition research: what the science actually says about coconut oil, MCT oil, blueberries, the Mediterranean diet, omega-3s, B vitamins, ketogenic diets, and more. What's signal, what's noise, and what the internet consistently gets wrong.The structure is deliberate: myths first, nuanced middle, then what actually has evidence. Because knowing what to be skeptical of makes the things that are genuinely supported land differently. If you've been eating well for years and wondering why nutrition advice keeps disappointing you — this episode is for you.Show Notes
