According to nutrition and health expert Professor Tim Spector, modern diets, particularly those rich in Ultra-Processed Foods (UPFs), are contributing to significant changes in the shape of children’s faces and jaws, resulting in a rise in dental and even breathing problems. Commonly consumed items such as cereals, crisps, soft drinks, and processed meats are increasingly linked to these concerning health issues.
A recent study in Spain has shed light on the impact of UPFs, revealing that children who primarily consume these foods develop weaker, softer jaws that fail to grow and mature properly. The research underscores the growing concern surrounding the high intake of UPFs in the UK, where they account for 55%-60% of total dietary energy intake—the highest percentage in Europe.
Ultra-processed foods are heavily industrialized products that contain ingredients not typically used in home cooking, including additives, preservatives, colorings, and artificial flavorings. Common examples include ready meals, sugary beverages, packaged snacks, and reconstituted meats. Beyond their convenience, these foods have been linked to a range of health issues, including obesity, cardiovascular disease, and type 2 diabetes. The overconsumption of these foods has also contributed to a decline in overall diet quality, marked by excessive sugar, salt, and unhealthy fats.
Dr. Laura Marques Martinez, the author of the study, highlighted the importance of chewing in the proper development of children’s jaws. She explained that chewing solid and fibrous foods—like fruits, vegetables, and natural proteins—plays a vital role in stimulating bone growth, strengthening facial muscles, and ensuring the proper alignment of teeth. Conversely, soft foods found in ultra-processed diets require minimal chewing, which deprives the jaw muscles and bones of the necessary stimulation for healthy development. This lack of stimulation can result in underdeveloped bone structures, increasing the risk of malocclusion (misalignment of teeth) and even respiratory issues.
UPFs, which include everyday foods like bread, oven chips, nuggets, and burgers, are intentionally designed to be easy to consume with little chewing effort. This convenience, however, is contributing to long-term health consequences for children, including dental and breathing complications that may worsen as they grow.
