Vitamin C supplements may reduce cancer risk linked to processed meat nitrates, according to new cancer research from the University of Waterloo. Scientists found Vitamin C can block harmful stomach reactions that create cancer-linked compounds after eating bacon, hot dogs, and deli meat. The study explains why spinach and leafy greens remain safer despite high nitrate levels. Researchers say pairing processed meats with Vitamin C-rich foods or supplements may help lower stomach cancer risk and improve digestive health outcomes.
