This research examines the relationship between ultra-processed food intake and the risk of postmenopausal breast cancer.
Analyzed dietary data from the NIH-AARP diet and health study cohort
Used statistical adjustments for body mass index (BMI)
Evaluated cancer incidence in relation to food intake
No association found between ultra-processed food intake and breast cancer risk.
Inverse trends observed after adjusting for BMI were deemed likely spurious.
Over-adjustment might have influenced perceived associations.
Abstract
UPF intake was not associated with postmenopausal breast cancer in the NIH-AARP cohort. Inverse trends observed after adjusting for BMI are likely spurious, owing to over-adjustment.
