What the Evidence Links to Ultra-Processed Foods

This 2024 review gathered the existing evidence, drawing on 14 meta-analyses covering nearly ten million people, on how ultra-processed foods relate to health. Ultra-processed foods are industrial formulations of extracted ingredients and additives, think packaged snacks, sugary drinks, mass-produced breads and ready meals. Greater intake was consistently associated with higher risks of early death, heart disease, type 2 diabetes, obesity and common mental disorders such as anxiety and depression, with the associations for mortality and mental health among the most convincing. The authors were clear that all the underlying evidence is observational, so it establishes association and cannot prove that these foods cause the harm, and the way ultra-processed foods are defined has its critics. For a woman navigating a busy life on convenience food, it supports gradually shifting the balance towards less processed meals as a reasonable, evidence-informed choice.
