Optimizing Membrane Composition With C15 and Choline: A Novel Hypothesis to Mitigate Cancer Risk
Year: 2025
Type: article
Abstract: Cancer incidence has dramatically increased over the past centuries, paralleling dietary shifts in Western nations. This narrative review evaluates whether excess dietary linoleic acid (LA) drives tumor initiation through membrane-mediated oxidative stress and chronic inflammation, and whether pentadecanoic acid (C15:0) and choline can restore membrane resilience and attenuate cancer risk. Historical epidemiological data and mechanistic studies reveal that rising cancer incidence tracks population-level LA exposure, while C15:0 and choline consumption have declined. In cellular and animal models, LA oxidation products activate pro-inflammatory and anti-apoptotic pathways. Conversely, C15:0 resists peroxidation and preserves mitochondrial integrity, while choline normalizes membrane fluidity. A precision-nutrition strategy restricting LA while fortifying C15:0 and choline offers a biochemically coherent complement to conventional oncology. Prospective clinical trials are warranted to validate whether correcting this lipid imbalance can reduce cancer incidence.
