I do. I've drastically revamped my diet. I will never eat fast food again, and I will not eat any foods that have any sort of preservative, additive, or other chemical that shouldn't be there. There are also a couple local farms near me that I plan on getting eggs, chickens, and fruits and veggies from.
It's overall more expensive, but I think it's worth it.
After a while, you might begin to discover that when your food is a higher quality, you need to eat less and you get more bang for your buck. So I think the added cost of a decent diet (including lots of organic, local produce whenever possible) balances out in the end.
