“Ultra-processed foods are toxic.”
Strong confidence because ultra-processed foods are a broad category, not a single toxic substance, and research does not show that every food in the category is poisonous or harmful. Higher-UPF eating patterns are associated with poorer outcomes, and one controlled trial found greater calorie intake on a UPF-heavy diet, but those findings do not make occasional or moderate intake toxic.
Ultra-processed foods are not toxic, and you do not need to eliminate them to be healthy. They can fit into a healthy diet. The practical concern is when less-filling, easy-to-overeat options make up a large share of what someone eats.
The category includes very different foods, from soda and candy to packaged whole-grain bread and fortified cereal. A label based on processing does not tell you everything about a food's nutrition or how it fits into your life.
Eating an ultra-processed food sometimes is different from building most meals around foods that are low in fiber, less filling and easy to overeat. Frequency, portions and the rest of the diet matter.
Can ultra-processed foods make eating more practical?
Yes. Some ultra-processed foods are affordable, convenient, fortified, shelf-stable or helpful when time and access are limited. Convenience can support health when it makes a realistic meal possible.
You can eat ultra-processed foods without guilt or fear. Aim for an overall pattern that includes enough protein, fiber, fruits, vegetables and other filling foods rather than trying to achieve a perfectly unprocessed diet.
Keep the convenient foods that work for your life, and add one filling or nutrient-rich food to a meal that needs it.
