S.L.
i'm not quite clear on the mamasource boards and how they work - i think you are from the greenville, sc area, but if you are not, disregard my answer! :)
whole foods market on woodruff road is a wonderful grocery store. offering organic and conventional produce, as well as packaged foods that contain NO high fructose corn syrup and NO hydrogenated oils, it is a wonderful place to procure healthy foods for your family. while i have never taken a tour of the store or one of their courses, i would encourage you to do that. they have calendars in-store telling times and topics. they'll give you a tour of the store, explaining their products, and they even offer some classes on how to feed your family.
also, the barnes and noble at greenridge has a great section on organics. enter the store and start walking back to the children's section. turn right just before you get there and walk to the back wall (pass the restrooms on your left). when you are about to run into the wall :), turn around 180 and the shelf in front of you holds cookbooks and general food info books on all kinds of special diets, lots of these books cover organics.
also, the library is a fabulous resource. i like to use its website and amazon.com in conjunction with one another. look up books on amazon by subject, read the synopsis, then search the greenville county library site for that book. request it online for pickup at your closest branch of the library.
while i have no specific recommendations for you, i encourage you to move forward with as much organic, whole food as you can afford for your family. look for specials at local supermarkets, and shop the state farmers' market on rutherford road. you'll find you may only spend just a little bit more (sometimes less!) on organic food than conventional...and in my case the extra amount i have spent on organics has been saved by avoiding excess medicines and doctors' bills. remember organic is not new - we've only been eating "conventional" foods for about the past 45-50 years, making us the guinea pigs in a dangerous experiment.
most of all, enjoy it, and be open to new flavors. :)
