Men who got the largest share of their calories from ultra-processed foods reported prostate cancer at higher rates than men who ate the least, according to an analysis of 17,024 US men published in The American Journal of Medicine. The finding lands in a country where these products supply more than half of adults' calories, with published estimates ranging from about 53 percent in recent federal survey data to nearly 60 percent, the figure the study authors cite.
The headline number is roughly 30 percent higher, but the details matter. In unadjusted analyses, men in the three higher-consumption groups showed a 29 percent greater risk and men in the two highest groups showed a 30 percent greater risk. After adjustment, those figures were 27 percent and 31 percent. Men in the highest group alone showed a possible 34 percent higher risk, though it did not reach statistical significance.
