Should I switch my dogs food?

Hello, when my lab was a pup i naturally took her to the vet and we were discussing food options. I told the vet I was feeding her 4health grain free puppy forumla and she said thay was great but recommend that i switch her to 4healths Large breed forumla as we both assumed shes be a larger lab as she was a big pup. Buuut shes a year old and 55lbs. So im wondering if I should switch her from large breed to another forumla 4 health offers, or does it not matter?
The pucture is thenutritional facts about their large breed forumla.
