When do I really need to buy organic?

I just returned from the grocery store and I always have to pull out my little cheat sheet on when to buy organic and when it doesn't matter so much. So I thought I'd pass this on to everyone so you can make your own cheat sheet.

The things you should always buy organic because conventionally grown these are typically sprayed with pesticides or chemical fertilizers:
Peaches
Apples
Sweet Bell Peppers
Celery
Nectarines
Strawberries
Cherries
Pears
Grapes
Spinach
Lettuce
Potatoes

These are typically ok to purchase conventionally grown:
Onions
Avacado
Sweet Corn (frozen)
Pineapples
Mango
Asparagus
Sweet Peas (frozen)
Kiwi
Bananas
Cabbage
Broccoli
Papaya

Milk, eggs, chicken and other animal products should be raised without hormones or antibiotics. Packaged and canned products are typically processed with all kinds of yucky stuff like high fructose corn syrup, so I usually opt for the organic versions or skip them altogether. Canned beans are where I'll make an exception (but rinse them before using). Read the labels!

There are differing schools of thought regarding whether or not frozen is as good as fresh. My thinking is that frozen veggies that are really fresh frozen and haven't thawed out are probably just about as good nutritionally as fresh, and are certainly better than canned or no veggies at all. The biggest unknown is whether or not they've been allowed to thaw along the way to the grocery store. But certainly if you are freezing your own veggies, are using really fresh veggies, and aren't leaving them in the freezer for a really long time, you should get just about as much nutrition value from them as if you had eaten them straight from the garden. But not everything freezes well, so I typically stick with things like corn, peas, butter peas, and okra. And I like frozen spinach too. No way are you going to have a frozen tomato that tastes as good as one right out of the garden! That said, you can freeze tomatoes for using in soups and stews. And it's really nice to be able to pull something like butter beans and corn out of the freezer in the winter to remind you that spring planting season is right around the corner!
