7. French Fries—Not only do French fries typically contain trans fats that have been linked to a long list of diseases, they contain one of the most potent carcinogenic substances in food—acrylamide. Acrylamide is formed when white potatoes are heated at high temperatures. Additionally, most of the oils used for frying turn rancid in the presence of oxygen or at high temperatures, resulting in foods that cause inflammation in the body. And, researchers are discovering that inflammation is a factor in many serious health conditions, including: heart disease, cancer, and arthritis.
6. Potato Chips—Potato chips offer all the health benefits (none) of French fries, but according to Health Canada, potato chips typically contain the highest levels of acrylamide, which is a carcinogen.
5. Bacon—Yes, bacon! Sorry bacon lovers. According to research in the journal, Circulation, daily consumption of processed meats like bacon can increase the risk of heart disease by 42 percent and diabetes by 19 percent. A study at the University of Columbia found that eating bacon 14 times a month was linked to damaged lung function and an increased risk of lung disease.
4. Hot Dogs—A study at the University of Hawaii found that consumption of hot dogs and other processed meats increased risk of pancreatic cancer by 67 percent. One of the ingredients found in both bacon and hot dogs is sodium nitrite. This carcinogen has been linked to leukemia in children and brain tumors in infants. Other studies show that sodium nitrate also promotes colorectal cancer.
