Reducing Ultra-Processed Foods Improves Metabolic Health in Older Adults
In a small, real-world feeding study of adults 65 and older, lowering ultra-processed foods to under 15% of calories (via two eight‑week diets—one meat-based, one vegetarian with dairy) led to natural calorie reductions, weight and abdominal fat loss, and improvements in insulin sensitivity, cholesterol, inflammation, and appetite/metabolism hormones, with similar benefits across both diet types; the study suggests realistic dietary shifts away from ultra-processed foods can boost metabolic health in aging populations, though larger, longer trials are needed.
