Calorie-free foods

Okay, so the title of this post is misleading. The 'calorie-free' foods listed in this article are not all truly calorie free, but their definitely low in Calories and good enough for you that they're worth consuming a few calories for. Anyway, here's the list of items that you should consume without consequence. Each as much of these as you want, eDiet's claims:

-Hot tea sweetened with splenda
-Berries
-Citrus fruits
-Sugar-free jello with sugar-free, fat free whipped topping
-Egg whites, prepared with calorie-free non-stick spray of course
-Veggies
-Water

I'm not a fan of artificial sweeteners and fat-free whipped topping has too many chemicals for my taste, so I'll stick to the fruit, veggies and water. What about you? What guilt-free foods do you snack on?
