We've come to learn that there are good and not-so-good fats and carbohydrates. Could the same hold true for protein sources? If so, then the type of protein that dominates a diet can influence health as much as the kinds and amounts of carbohydrates or fats. It's highly unlikely that anyone will ever launch a 10- to 15-year-long randomized trial to explore the effects of diet on heart disease, cancer, or longevity.
