The fiber fix for lower cancer risk
Dietary fiber remains a key nutritional factor in decreasing the risk of several cancers, with strong evidence supporting that both soluble and insoluble fiber contribute to this protective effect through distinct biological mechanisms. Studies demonstrate that fiber’s benefits arise from its ability to modulate the gut microbiome, reduce inflammation, and improve bowel motility, thereby decreasing mucosal exposure to carcinogens. In the Philippines, colorectal cancer is the third most common cancer with 20,736 new cases in 2022, while breast cancer is the leading cancer among Filipino women, accounting for 33,079 new cases (GLOBOCAN, 2022), highlighting the need for preventive strategies, particularly nutrition‑focused interventions. As cancer incidence continues to rise locally, promoting a fiber‑rich diet offers a practical, public health approach to reducing cancer burden in the country.
