Diet was assessed using validated food frequency questionnaires (FFQs) every 4 years. We estimated UPF intake using the NOVA classification, which groups foods according to the degree of their processing. In secondary analyses, we classified UPF into their components, including ultraprocessed grain foods, sweet snacks, ready-to-eat meals, fats and sauces, ultraprocessed dairy products, savory snacks, processed meat, beverages, and artificial sweeteners.
