Do you put butter on the veggies? What about cheese? Those add calories real quick to a meal.
Don't listen to the bad advice of giving her artificial sweetener drinks instead of juice. They are MUCH WORSE and they say that they make the body react like sugar when it comes to diabetes which seems to be a problem for children these days. But do try to avoid drinks sweetened with high fructose corn syrup which is worse then sugar. The sugar in 100% juice is natural, not refined and not corn syrup which SOOO much better for you.
Each 12-ounce can of soda contains the equivalent of 10 and 12 teaspoons, or 1/4 cup, of sugar. So despite one poster's comment that sweet tea is just as bad as soda, this is not true either (at least I don't put that much sugar in my tea!) You can add some powdered vitamin c for some added citrus tartness and even some tasteless powdered fiber. That would make tea a much better flavored drink then soda. She could even have it sweetened with fruit juice instead of sugar, adding more benefits.
The sugar in milk and juice IS a problem though and make sure you limit those portions to 4 oz of 100% real fruit juice a day (remember, you don't want empty calories, so make sure it's not a 'cocktail') and 16 oz of skim milk a day. Remember that when she gets yogurt or cheese it substitutes milk.
Bananas are full of sugar so half a banana is one portion. Again, it's natural sugar which is far superior to refined sugar.
Sweetener substitutes better then the artificial stuff:
honey, agava, stevia- the last two can be found in the healthfood section of your grocery store and are not chemicals.
Oh, watch out for the starches, especially refined flours but even the whole grains she shouldn't have a lot of breads and potatoes and rice. The body turns them into sugar.
I hope this helps,
