Do you buy organic food?
If its available in organic I buy it. I love that Costco carries so much organic stuff now. I make sure all meat, dairy, eggs and fruit / veggies that I don't peel are organic.
Some things, I try to buy hormone free milk/chicken but not always 100% organic. Also on some fresh veggies I try to buy organic to avoid some of the chemicals.
I do, but not everything..
