Hot Dogs and Processed Meats

Hot dogs and other processed meats, classified by the WHO as Group 1 carcinogens alongside tobacco, contain nitrites that form nitrosamines during digestion—directly linked to colorectal cancer in dose-dependent studies. Each 50g serving—just one hot dog—raises colorectal cancer risk by 18%, a danger that surpasses #1 sugary cereals in cancer terms. With 1,000mg of sodium per link, they also outstrip the average deli meat in blood pressure impact.
