Gluten is a protein naturally found in some grains including wheat, barley, and rye. It acts like a binder, holding food together and adding a “stretchy” quality—think of a pizza maker tossing and stretching out a ball of dough. It’s common in foods such as bread, pasta, pizza, and cereal. Gluten provides no essential nutrients. People with celiac disease have an immune reaction that is triggered by eating gluten.
Studies are finding a link between people’s “subjective age” or “psychological age” and their future health and longevity. Psychological age can differ from chronological age, and some psychologists and gerontologists say there might be ways to improve physical health by making yourself feel younger—or at least taking a positive attitude toward aging.
