1. Red and Processed Meats
The World Health Organization (WHO) announced in October 2015 that processed meats (e.g., sausage, ham, jerky, hot dogs, etc.) have been categorized as Group 1 carcinogens, which means there is sufficient evidence that they cause cancer in humans, including prostate cancer. Red meat has received a Group 2A classification, which means beef, pork, lamb, mutton, horse, goat, and veal are probably carcinogenic to humans. These conclusions were made after extensive review of more than 800 studies by an international team of 22 scientists from ten countries. Subsequent reports, including one published in the Asian Pacific Journal of Cancer Prevention and another in Cancer Prevention Research (Philadelphia), have pointed to an increased risk of prostate cancer associated with meat consumption in general, as well as eating red meat and processed meat, or risk of recurrence in men already diagnosed with the disease. Meat consumption can contribute to cancer risk and progression in several ways, including introduction of excess hormones that can trigger an imbalance and the presence of insulin-like growth factor-1 (IGF-1), which can cause the spread of cancer cells.
Tip: If you can’t give up meat altogether then limit the amount of servings per week and only buy organic meat raised without antibiotics or hormones.
