Ultra-processed foods
no changein humans1HR 0.97
Ultra-processed foods have no effect on colorectal cancer incidence in humans (HR 0.97, 95% CI 0.91–1.03; ptrend = 0.55).

Meat

Meat is associated with colorectal cancer incidence in humans.
“Whole grain, fiber, dairy, and calcium intakes from UPF sources were inversely but meat intake from UPF sources was positively associated with CRC incidence.”
