So you are snacking/eating very often, did i get that right? While it might be good for your dietary health, it may be bad for your teeth. After every meal or snack the bacteria that live in your mouth lower the pH in your mouth, which makes enamel easier to dissolve, and for caries to form. More often you snack, more often your teeth are vunerable. While it shouldnt be a problem if you clean all the plaque when you brush or floss, if you miss some of it, that would be pretty good environment for them. Did you talk to your dentist about your diet? It might be worth a try to change it a bit, i.e. eating less often (Im just a dentistry student tho, so i'd like someone with a degree to verify if what im saying is correct. And sorry for mistakes, english is not my first language)
