Hi--
They've backed off on too much juice--it use to be a serving a day was okay but now they've decided that you can have one or two. Of course, you have to be careful which juice you pick. Since high fructose corn syrup is in almost EVERYTHING (bread, ketchup, jelly/jam, etc.) you have to watch for it in juice but I found Juicy Juice and TreeTop to both by just juice. Nothing more, nothing less. My family loves it and I do keep them down to two servings a day as a piece of fruit offers more, like fiber.
I also make a combination of Wylers (like Crystal Lite but less expensive) sugar/caffeine free tea with lemon and lemonade. I use a pack of each in a gallon jug and it's wonderful (also good hot).
I pack Minute Maid's Fruit Falls (found by the Capri Sun) in their lunches. This is water with 5% fruit juice. Kids and husband LOVE it and if I'm not careful they'll drink it instead of everything else. :) If you have a WinCo near you you can get a pack of ten for $2.28.
As for snacks, my kids love string cheese and yogurt and tortilla chips (have to be careful about that), bananas, apples, grapes, oranges, blah blah blah and Costco has a fruit roll up that's organic and each one is 1/2 serving of fruit--I forget the name but it's like four letters and two of them are U's but all I can come up with is Fubu and I don't think they've branched into food yet.
A safe bet for food sources is Trader Joe's (if you have one) or Whole Foods. Trader Joe's is quite affordable and they have a high standard for the food they stock. If you have a First 5 center near you (there are a bunch in Contra Costa County--Brentwood, Antioch, Concord, Richmond) you can contact them for healthy eating choices. This is a statewide organization that is committed to creating healthy, happy children 0-5 in our communities though the information is good for everyone. You can also contact your local WIC--the one in Pittsburg is very excited about helping you feed your children nutritious food and getting them active. :)
Have fun--there are bunches of good choices out there (you just have to sort through all the cheap, not-as-good for you stuff.)
