Hello,
I think I'm pretty lucky to live in the Central Valley of California, where most produce that we eat in the US is grown (when it's in season, anyway). So I may have an advantage in that we have lots of farmer's markets and many, many organic farms within driving distance of our house. However, I would imagine that there are community farms near your home as well. I found a service near my house where a local farmer will deliver fresh fruit and produce, all grown organically and locally, right to my doorstep once per week. It's so wonderful because the produce is picked when it's ripe, not weeks beforehand and then gassed to bring on color, like most produce you see in grocery stores. Asking around to friends who live around the country, they have been able to find similar farms in their areas. Do you have a farmer's market nearby? That's a great resource. You just have to make sure that they actually grew what they're selling. Another great alternative is to plant a little garden in your back yard. You can even plant them in your flower beds (who says tomatoes aren't as beautiful as petunias?)
My mom, who lives in Salt Lake City, recently signed up for an organic meat delivery service. She went out to the farm where the animals are raised to see the conditions, and saw that they were being fed properly, had plenty of room to move around, and were kept in a clean environment. She says the meat is absolutely fantastic! So, that's the next thing I'm looking into.
Also, not to freak you out even more, but have you researched milk at all? The next county over from us is the biggest milk producer in the country, and commercial dairy farms are absolutely frightening. In my opinion, organic isn't quite enough where they are concerned. We actually buy raw organic milk from a local farm (Organic Pastures). They have beautiful, clean, happy cows and their facility is spotless. The milk tastes incredible and my kids do not seem to be sensitive to dairy when it's raw (pasteurized milk really gives them digestive problems).
Anyhow, like you, I've become more and more concerned with what I'm feeding my kids. I'd consider myself to be pretty lazy when it comes to cooking, actually, but it's just really hard to feed your kids stuff that will harm them. Especially when it's not necessary and other options are available. Just do what you can for now and keep researching more ways to introduce healthier foods into your kitchen!
