A global study that analysed brain scans from around 30,000 individuals revealed links between eating ultra-processed foods (UPFs) and measurable differences in brain structure. These brain changes may be connected to patterns of overeating, potentially creating a cycle that reinforces unhealthy eating behaviours. UPFs contain ingredients rarely used in home cooking, such as emulsifiers, flavour enhancers, artificial sweeteners, and preservatives. These include packaged snacks, sugary cereals, soft drinks, and processed meats, which tend to be high in calories, salt, and added sugars while lacking essential nutrients.
