Too often, gluten-free diet information focuses only on things you cannot have. With this intense focus on what to avoid, the message about what of the many gluten-free foods you can—and should—eat for good health often gets lost. The most nutritious gluten-free diet is one based around healthy, gluten-free, whole foods, such as vegetables, fruit, beans, grains, nuts, seeds, lean meats, poultry, and fish. Over-reliance on heavily processed, convenience foods can result in a diet that lacks important nutrients, including B vitamins, iron, calcium, and fiber, for good health.
