Foods high in omega 3's would be all fish.
High in omega 6's vegetable oils, nuts, etc
The importance is to maintain a good ratio of 3's to 6's
Ideally you would want to consume more 3's than 6's. So you try to get as close as possible to a 1:1 ratio.
The ratio for some foods is higher than others. I know nuts can have a really unbalanced ratio, leaning alot more towards the 6's.
Those are just the basics.
"I know what my body needs and what it can handle. There's no better way to achieve my goal than what im doing now. If my regimen leads to my death, be it in six days or six months...I will die fullfiled. The outcome is irrelavent so long as i steer towards my fate. If death is to be my prize, i welcome it with open arms."
