I'd like to second the comment about being "out in the world." I feel like I can't take my daughter to playgroup at the library because they load the kids up with sugary fruit juice and cheap cookies (loaded with HF corn syrup). And she's not the kind of kid who will munch on plain popcorn when there are cookies available, KWIM? Worse are the people handing her candy everywhere we go. She loves it, of course, but really? Is it necessary to hand every toddler a lollipop?
Also, people have been brainwashed into thinking that certain kinds of processed foods are "healthy." My MIL, for example, buys nonfat yogurt sweetened with aspartame and loaded with fake fiber, and she's always trying to give it to DD because it's "healthy food." Yuck!!!! I try to explain that there are all sorts of things in there that she shouldn't have, but to no avail. There are plenty of other examples of this: my DH thinks that Jif is healthy because it's peanut butter (I keep explaining that it's mostly hydrogenated oil) and Kraft singles, because they're cheese (no, there's not actually any cheese in there at all). And don't even get me started on all the "healthy vitamin juice drinks" and "natural fruit snacks" that are nothing but sugar-water and candy in fancy expensive packaging.
And restaurants, restaurants are the worst!!! Why is it that every food establishment in the Western hemisphere equates "kid food" with things that are a) fried, b) artificially flavored, c) loaded with meat, or d) loaded with sugar? I usually can't find an edible meal in any kids' menu for DD. I usually have to ask, "don't you have vegetables? or fruit?" then I get a bowl of sugary canned peaches or something. Ick. My daughter will happily eat pasta, vegetables, rice, curry, baked potatoes, cheese, beans, buttered bread, fruit, and soup -- why aren't any of those things on the children's menu?
