Dunkin’ Donuts has announced their new line of gluten-free donuts, such as gluten-free Cinnamon Sugar Donut and a gluten-free Blueberry Muffin. If it’s gluten-free, it must be good! Right? ---- Wrong. Fatally, irreversibly wrong. Dunkin’ Donuts is not the first to make this nutritional blunder. Post, Kelloggs, Nabisco, as well as Udi’s, Schar, and Glutino, have all demonstrated their incredible ignorance on nutritional issues, or at least their indifference.
