"The design of these clinical trials... makes it very difficult to attribute the unfavorable effects of UPF-rich diets to ultraprocessing per se... these effects are highly likely to be due to differences in traditional nutritional properties that frequently—but not uniformly—co-occur in UPFs."
Noémie Bouhana
"Collectively, available randomized controlled trials provide weak support for an ultraprocessing-specific effect of UPFs on body weight regulation and cardiometabolic function that is independent of established nutritional determinants."
