Abstract

Diet habits have been shown to affect numerous diet-related cancers, for instance, colorectal cancer, oral, nasopharyngeal, and esophageal cancers, pancreatic cancer, lung cancer, etc. This study investigates the relationship between the evolution of dietary guidelines and incidence rates for certain diet-related cancers in the United States (U.S.) and Australia over a 15-year period (2003-2017). Employing an extensive comparative analysis, the study aims to unveil potential associations or divergences between advocated dietary habits and the occurrence of distinct diet-related cancers. The findings reveal a correlation between shifts in recommended dietary patterns and changes in colorectal cancer incidence rates. Notably, changes in guidelines emphasizing reduced red and processed meat intake align with consistent downward trends in colorectal cancer incidence rates. Pancreatic cancer incidence rates, on the other hand, exhibit upward trends despite guidelines promoting increased vegetable and fruit consumption, reinforcing the inconclusiveness regarding the relationship between dietary habits and the occurrence of pancreatic cancer. This investigation marks a crucial initial step in understanding the intricate relationship between recommended dietary patterns and their potential impact on mitigating certain cancer types.
