Overwhelmingly I've been amazed to see that most people seem to have no regard whatsoever for their nutrition. Things go into their body but it often has 0 nutricional value.
Also - it's actually really really hard to eat well. Since so many restaurants cater to what people are familiar with, there's next to no alternative for people trying to eat nutritious food.
Not to mention it's expensive. I spend about $1200 a month just at Whole Foods, mostly on organic and raw foods. And that's just for myself.
Pesticides scare me. Especially since I can't be bothered to wash my food before eating it. But as I understand it, if you use pesticides, then the plants don't produce their own natural chemicals that fight off pests and other symbiotic organisms. I don't remember where I read it but according to my research those chemicals are very beneficial part of the total nutriment.
Also, organic foods are nutritionally equivalent to conventionally grown foods according to the most recent research; you may want to reconsider your budgeting on that front.
