Should your granola bar come with a warning label?

Concern is rising about the amount of ultra-processed foods in American diets, and the effect eating so many of those foods has on our health. Part of the problem, nutrition researchers say, is that lots of healthy-seeming items—many breakfast cereals, soups and yogurts as well as granola—fall into that category. Recent studies have linked diets high in ultra-processed foods to increased risks of obesity, Type 2 diabetes, cancer, cardiovascular disease and depression.
