Nutritional status, brain network organization, and general intelligence

I'm too dumb to understand this presumably due to poor nutrition. Can someone explain?

From everything I've put together, canola oil is the way to go. Highest omega3/6 ratio and same amount of monounsaturated fats as olive oil.

I disagree completely. Canola is easily oxidizable.

Why bother paywalling me Elsevier, you know I'm going to get what I want for free. You're my bitch.
