I'm not real clear on the question.
For normal, healthy dogs I think a wide variety of foods is best. Just like with normal, healthy humans. At least in theory it likely makes them (and us) healthier over the long haul.
But for dogs with health issues that may be related to foods (allergies, IBD, seizures, digestive sensitivities, etc.) a wide variety of foods is likely to do more harm to their health than good.
Look at it this way -- I don't have any particular health issues, so I try to get some whole grains in my diet every day. Whole wheat bread and pasta, etc. Lots of nutrients and fiber and complex carbs that are really good for me and help keep me healthy. But that same whole wheat bread that's great for me would be horrible for someone with celiac disease. It would do them more harm than good.
But I do think that even dogs with medical issues related to diet should be fed as widely varied diet as possible (even though it can't be as varied as the diet of a healthy dog could be).
