Long-Term Nitrite Intake Linked to Higher Colorectal Cancer Risk in Men, Swedish Study Finds
A Swedish analysis of two large cohorts (82,009 participants) over 20 years links higher dietary nitrite intake to greater colorectal cancer risk in men (HR 1.23 for highest vs lowest quintile; p-trend = 0.05), strongest for distal colon cancer (about 50% higher). No association with nitrate or in women. Men reported higher nitrite exposure partly from meat, while women mostly from vegetables. Limitations include self-reported diet and possible confounding; more research is needed to understand why men are affected.
