Kroger and HEB have the best organic selection. If you watch, you can get organic produce for not much more then $1 a pound at Kroger, and 3 pound bag of apples at Kroger, HEB , Walmart and Target for a little over $3!
Organic ketchup is important because the riboflavins (I think that's what it is, the cancer fighting thing) is higher in organic. Also, risperal (also cancer fighting) that is known for being in grapes is actually in the organic grapes, not the non organic, they found it occurs as a response to fungai growing on the grapes!
Organic butter and other items with a higher fat content is supposedly important because the higher the fat, the higher the toxins it will retain.
We eat a lot of fresh foods- I don't always get organic but have few processed items. I figure that just because it's organic doesn't mean it's good for me. Still, if it's organic and processed it's not going to have chemical preservatives and HFCS, as they don't come in an organic variety. *grin*
Recipes- whatever you'd do with non organic you can do with organic. I love salads with craisins and nuts and sesame seeds. I buy Hormel's natural lunch meat that has no nitrates, hormones, ect and will slice that up and put it in my salad or free range boiled chicken egg chopped up.
Organic doesn't have to be expensive, shop around.
I really like Whole Foods but unfortunately there isn't one close to you. Check out American Healthfoods on 45 and 1960. Head south on 45, right on 1960, uturn back toward 45 and go into the strip center on your right hand side. There's a furniture store and a pub there closest to the store. http://www.americanhealthfoodshouston.com/ They are very knowledgeable and have a lot of items.
Someone suggested local farmers markets. Actually, the ones I have been to have very little if any organic produce (but at least they are cheaper then the grocery stores.) I do know of one that sells a lot of organic items- friends of mine started it and sell there- Tomball Farmer's Market. http://www.tomballfarmersmarket.org/
