I also went through that period. When you start looking even deeper you find that it's not actually the food that matters but your light environment. People that live in low latitude environments can deal with seed oils for example, but if you live in the US or Europe they are indeed absolutely bad for you.
Just eat what is created in the same environment as you live in and has as little human interference as possible.
Put simply, you want as little deuterium as possible and as much sunlight as possible. Animal meat from your own environment happens to be the easiest way to meet the right criteria so I still am carnivore.
My point being, those that point to meat are only coincidentally correct that it's probably the best option for you.
