This includes beef, pork, and lamb, along with items like sausages, hot dogs, bacon, and deli meats. According to research, eating large amounts of red and processed meat, especially when cooked at high temperatures, can increase the risk of prostate cancer. This is because cooking meat at high heat creates harmful chemicals called heterocyclic amines (HCAs), which may damage cells and lead to cancer. If you really want to eat red meat, limit its consumption to once or twice a month only, and avoid deep frying it.
