If you're looking for a ball park treat, you might want to toss the traditional frank in favor of some nachos and popcorn. According to LiveScience, researchers at the University of Nebraska Medical Center have grown increasingly wary of their hotdogs, suggesting that the meaty treat "may contain DNA-mutating compounds that might boost one's risk for cancer." And while there are definitely a lot of "mays" and "mights" in that last statement, the damage seems to come from the fact that most hotdogs are preserved with sodium nitrate. When combined with other substances, the theory suggests sodium nitrate forms chemicals known as N-nitroso compounds, which can trigger colon cancer. And while mental_floss will wait patiently for further evidence before passing judgment on "the dog" we did want to send a word of warning to this guy.
