“if you're only meat and you don't eat fish, if you eat animals besides fish, you're not getting a lot of them. And they're they're the building blocks of the brain. So, we need a lot of them.”
If you don't eat fish or seafood, you are not getting enough omega-3 fatty acids, which are building blocks of the brain that the body cannot make itself.
The expert's claim has two components: (1) that non-fish eaters are deficient in omega-3s, and (2) that omega-3s are essential brain building blocks the body cannot synthesize. The second component is…

“There's no molecule that's perfectly safe. Even fish oil, I think has warnings on it. So, um if you're 20 and you're going to do this for your whole life, that's a greater risk than someone like me who's 50, you could argue.”
Even fish oil has warnings on it, meaning no supplement is perfectly safe, and long-term use starting at a young age carries greater cumulative risk.
The claim that fish oil carries warnings is partially supported: the RCT on fish oil and perioperative bleeding (PMID 30571332) directly investigated a commonly cited safety concern (bleeding risk bef…
