Get your macros organized properly first and figure out what you should be eating (i.e - a diet plan).
Then note what fruits and vegetables you prefer and buy organic or non-organic based on the pesticide amount that the plants test positive for.
It's more effective, in terms of reducing bodily harm and cost, than just going full blown organic on everything. You have to tailor your approach or you're just throwing money away to hipster assholes.
Here's some links to help you figure it out -

Since I'm poor, the only vegetables I buy are broccoli, sweet potatoes, onions, and cauliflower, since it doesn't matter if they're organic or not.
The rule of thumb here is that if they have a lot of surface area (lettuce, spinach, etc), then you should buy organic. For fruits, buying organic everything is probably a good idea - especially with berries. I eat more vegetables than fruits anyway.
All of my leafy vegetables like lettuce and spinach I grow in the garden and just make sure to eat piles of it during the summer. The same goes for apples and strawberries since any that you buy from the store have shitloads of pesticides. That's 100% organic.
Eating vegetables can be kind of a pain but I have learned that you can fry and/or juice nearly anything. If it doesn't taste good when fried in butter and covered in salt then something isn't right.
I also think that the future of vegetables is going to move more towards eating weeds (basically) as people try to avoid GMO crops and shit like that. There's some oldschool earth children hippies at the local farmer's market who sell stinging nettles, watercress, dandelion greens, purslane- among other bizarre things. I must chat with them too much because some of the crazy beliefs are rubbing off on me, like that watercress can prevent cancer and dandelion greens are nature's viagra. Here's a link anyway --
