A groundbreaking preclinical study has upended conventional dietary wisdom by demonstrating that oleic acid—the primary fat in olive oil—accelerated pancreatic cancer development in genetically predisposed mice. Conversely, omega-3 fatty acids from fish oil reduced disease development by approximately 50% in the same model.
Researchers fed genetically modified mice enriched diets containing different fat types and observed striking differences in tumor progression rates. Mice consuming oleic acid showed 85% tumor development compared to 60% in control groups, while those receiving omega-3 supplementation developed cancer in only 35% of cases.
The findings challenge the assumption that all dietary fats pose equal cancer risks and suggest that fat composition may be more critical than total fat intake for pancreatic cancer prevention, particularly in individuals with hereditary predisposition. Read the full article on GMJ Newsroom.
