Breakfast choices significantly impact health, with certain foods linked to heightened mouth cancer risks. Ultra-processed foods (UPFs), including sausages, breakfast cereals, mass-produced bread, and fruit-flavored yogurts, contain carcinogens or unhealthy additives. A British study linked UPF consumption to a 23-24% increase in head, neck, and esophageal cancer risks, emphasizing the importance of monitoring food intake to reduce cancer risk.
