Understanding how diet shapes the gut microbiome—and how these microbial shifts influence cancer risk—is a critical question in cancer prevention research.
As large population cohorts mature and multiomics technologies advance, researchers are now able to improve our understanding of the relationship between diet, the microbiome, and cancer.
Dr. Mingyang Song, associate professor of clinical epidemiology and nutrition at the Harvard T.H. Chan School of Public Health, aims to identify nutritional and gut microbiota-targeted strategies for cancer prevention and treatment.
Technology Networks spoke with Song ahead of his talk at the American Association for Cancer Research Annual Meeting (AACR 2026) to discuss how large‑scale cohorts and clinical trials can be combined to uncover causal links between diet, the gut microbiome, and cancer risk. He also shared what recent findings reveal about food–microbiome interactions, how microbiome‑informed tools may reshape colorectal cancer screening, and the challenges of personalizing dietary recommendations.
Integrating cohort studies and clinical trials to reveal causal diet–microbiome–cancer pathways
How do you approach integrating large-scale cohort studies and biomarker-based clinical trials to uncover causal links between diet, the gut microbiome, and cancer risk?
Large prospective cohorts remain the backbone of population‑level cancer epidemiology, offering the statistical power to detect associations between dietary patterns, microbiome features, and disease outcomes over time. Song explained that these datasets allow researchers to “study the patterns of diet and the microbiome in relation to the disease outcome and identify associations.”
“We use population-based cohort studies to identify associations, and then conduct clinical trials to confirm these observations.” —…
