1. Red and Processed Meat
Eating a lot of red and processed meats is unhealthy for several reasons, one of which is it may increase your risk of prostate cancer. Studies show that men who ate the most red meat were 12 percent more likely to develop prostate cancer and 33 percent more likely to have advanced cancer than those who ate the least amount of red meat.
2. Nonorganic Meat
Nonorganic meat encompasses the majority of the meat available on the market, including beef, pork, lamb, veal, and poultry raised using conventional methods that involve the use of hormones, antibiotics, and steroids, as well as animals being fed food they were not meant to eat. Cattle, for example, evolved to eat grass, but they are fed corn, soybeans, and other grains because it fattens them up faster for slaughter. When you do include meat in your diet, make it organic so you can avoid the additives that can have a negative impact on both prostate and overall health.
3. Calcium and Dairy Foods
Dairy foods are the most common source of calcium in the United States, and this is a source of concern for two reasons. One, the American Cancer Society notes there is evidence that high intake of calcium, mostly through supplements and dairy foods, has been linked with a greater risk of prostate cancer, especially aggressive cancer. Two, many dairy foods are high in fat and cholesterol, and may also contain hormones, all of which can have a negative impact on prostate health
4. Canned Tomatoes and Tomato Products
Although it is true tomatoes and tomato products support and promote prostate health, especially because of their high lycopene content, you should avoid tomato foods packaged in cans. The resin linings of tin cans contain bisphenol-A (BPA), a synthetic estrogen that can leach into the tomatoes because they are acidic. BPA is associated with an increased risk of cancer and other health problems.
5. Microwave Popcorn
Popcorn is a good source of fiber, but avoid microwave popcorn. The lining of the bags in which microwave popcorn is popped contains chemicals, including perfluorooctanoic acid (PFOA) that may be associated with infertility in humans. The chemicals have also been linked to cancer in lab animals. Because PFOA accumulates in the body, scientists worry that the chemical may reach a cancer-causing level in people who are exposed to it for too long. The makers of PFOA have promised to stop producing the chemical by 2015.
