Hot Dogs May Cause Genetic Mutations
As if there weren't enough reasons to be vegetarian...

Quote: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.

It's really a shame that lawsuits have created an environment where researchers won't name the brands with the highest concentrations of cancer causing agents. This was also the case when the acrylamide threat came into play a few years back.
&Having raised the earth's temperature 1 degree Fahrenheit in the last three decades, we're facing another increase of 4 degrees over the next century. That would imply changes that constitute practically a different planet. It's not something we can adapt to. We can't let it go on another 10 years like this.& - NASA's Goddard Space Institute Director James Hansen
