A lot of the metabolic effect of foods depends on what goes with it in a meal - potatoes, rice, or pasta can be a plus or a minus depending on how much of them you eat, certainly, but also what sort of sauce you douse them with. Mashed potatoes made with half a pound of butter, and gravy on top, won't be as healthy as mashed potatoes made with buttermilk and chopped green onions/ scallions/ spring onions. Pasta Alfredo won't be as healthy as pasta tossed with sardines and capers, iyswim.
