Preservative free - where to start?

We've noticed a change in behavior when DD eats frankenfoods. We asked the pedi and she strongly recommended going preservative free.

Where do I start? I try to give her some whole foods (usually fruit) but what else can I give a kid who loves nutragrain bars and yogurt? She's 3 so tough to eat raw veggies aren't really something we can do just yet. I need some ideas for quick snacks besides fruit because I work full time.

I am gluten and sugar free but she can have these things without a problem. We have a Whole Foods in town and are getting a Trader Joe's in a couple of weeks so i have access to stores that carry this stuff.

I feel like I should know this and feel stupid for asking. :eyeroll:

TIA ladies!

Try Chobani greek yogurt. I'm almost positive that it doesn't have anything artificial in it and it's very tasty.

What about cheese? I think oscar mayer just started a line called selects that has deli meats that are preservative free.

Have you made your own granola bars? We're GF here also and I make some excellent granola bars that the kids and my husband love. They use honey instead of sugar I believe and the only preservatives would be if you used chocolate chips but I usually put in raisins or dried cherries.

I second making your own bars. We are also gluten free and I make a really simple gluten free oat bar with just peanut butter and honey.
