Hot Dogs May Cause Genetic Mutations

Everyone knows hot dogs aren't exactly healthy for you, but in a new study chemists find they may contain DNA-mutating compounds that might boost one's risk for cancer.

Scientists note there is an up to 240-fold variation in levels of these chemicals across different brands.

"One could try and find out what the difference in manufacturing techniques are between the brands, and if it's decided these things are a hazard, one could change the manufacturing methods," researcher Sidney Mirvish, a chemist at the University of Nebraska Medical Center in Omaha, told LiveScience.

Mirvish and his colleagues examined hot dogs because past research had linked them with colon cancer. Hot dogs are preserved with sodium nitrite, which can help form chemicals known as N-nitroso compounds, most of which cause cancer in lab animals.

Extracts from hot dogs bought from the supermarket, when mixed with nitrites, resulted in what appeared to be these DNA-mutating compounds. When added to Salmonella bacteria, hot dog extracts treated with nitrites doubled to quadrupled their normal DNA mutation levels. Triggering DNA mutations in the gut might boost the risk for colon cancer, the researchers explained.

.... We know Nitrites Cause Cancer. So Why are we still putting it in food. It is in a lot of processed meat, not just hot dogs....

Consumer Warning:
Processed Meats Cause Cancer

Processed meat consumption results in 67% increase in pancreatic cancer risk, says new research
Consuming processed meats increases the risk of pancreatic cancer, says new research conducted at the University of Hawaii that followed nearly 200,000 men and women for seven years. According to lead study author Ute Nothlings, people who consumed the most processed meats (hot dogs and sausage) showed a 67% increased risk of pancreatic cancer over those who consumed little or no meat products.

But researchers failed to accurately identify the culprit responsible for this increased risk of pancreatic cancer, says one author. The true cause of the heightened cancer risk is the widespread use of a carcinogenic precursor ingredient known as sodium nitrite by food processing companies, says nutritionist Mike Adams, author of the just-published Grocery Warning manual.

Nearly all processed meats are made with sodium nitrite: breakfast sausage, hot dogs, jerkies, bacon, lunch meat, and even meats in canned soup products. Yet this ingredient is a precursor to highly carcinogenic nitrosamines -- potent cancer-causing chemicals that accelerate the formation and growth of cancer cells throughout the body. When consumers eat sodium nitrite in popular meat products, nitrosamines are formed in the body where they promote the growth of various cancers, including colorectal cancer and pancreatic cancer, says Adams.

"Sodium nitrite is a dangerous, cancer-causing ingredient that has no place in the human food supply," he explains. The USDA actually tried to ban sodium nitrite in the 1970's, but was preempted by the meat processing industry, which relies on the ingredient as a color fixer to make foods look more visually appealing. "The meat industry uses sodium nitrite to sell more meat products at the expense of public health," says Adams. "And this new research clearly demonstrates the link between the consumption of processed meats and cancer."
