A new 50-year analysis from the University of Michigan has revealed a strong link between ultraprocessed foods and binge eating, with 70 percent of foods consumed during binge episodes being ultraprocessed. The study, covering data from 1973 to 2023, found that only 15 percent of binge foods were minimally processed, such as fruits and vegetables, and it was rare for individuals to binge solely on these healthier options.
The researchers suggest that the findings highlight a 'major blind spot in eating disorder research,' as the types of foods involved in binge eating have largely been overlooked. Binge eating began appearing in scientific literature in the 1970s, coinciding with the rise of highly processed foods in the food environment, yet research has rarely examined how these foods might contribute to the disorder.
Common binge foods identified include cake, ice cream, cookies, chocolate, pastries, pizza, and chips. These products are designed with refined carbohydrates and fats that make them easy to overconsume. The study raises questions about whether these foods are simply over-consumed or are engineered to promote binge-like patterns.
Binge eating is now the most common eating disorder in the US, with a 1 to 3 percent chance of developing the condition. It can lead to weight gain, obesity, heart disease, Type 2 diabetes, gallbladder disease, and depression. The findings underscore the need for further research into the role of ultraprocessed foods in eating disorders.
