I wouldnt put your toddler on strict lc like we as adults do, but you can for sure cut back the actual amount of processed foods and stuff she eats. I have basically just started cooking everything from scratch, I dont like to feed my little girl anything out of a box and it has really helped. She loves fish of all kinds so that has been a plus too. We have her on Primal Defense from the health food store on a suggestion from our holistic vet, who is a very very good friend of ours and that has helped a ton. It just helps your intestines to get rid of the bad build up. I switched my family to the crystal light or even the walmart brand of sugar free drinks and they love it. We eat alot of veggies, mostly fresh or frozen, and I give her apples, oranges, etc. just because I think kids need alot fruits.

Good luck and just keep working at it. My kids love to snack on cheese, so I buy them string cheese, nuts of all kinds, just good healthy foods.
