The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
The other compound that has been shown to be directly supportive of neuronal function is phosphatidylserine, which is abundant in meats and in fish. So here we are again back to fish being an important source of brain supporting food. Phosphatidylserine is something that, nowadays, people are supplementing. It's a lipid-like compound that, at least in three studies, have been shown to improve cognition. These weren't huge effects, but they were statistically significant effects. And as well in more than three, at least five studies, to reduce cognitive decline.
