Nothing says red, white, and blue more than grilled meats, cold beer, and legal explosives in the form of firecrackers. But what if hot dogs, an all American July 4th favorite, increased your risk of heart disease by some 42 percent and diabetes by 19 percent? Not to be a Debbie Downer, but the stats don’t lie.
"To lower risk of heart attacks and diabetes, people should consider which types of meats they are eating," said Renata Micha of the Harvard School of Public Health. "Processed meats such as bacon, salami, sausages, hot dogs and processed deli meats may be the most important to avoid," Micha said in a statement.
Her report, published in the journal Circulation, reviewed 1,600 separate studies to investigate the differences in health risks between processed and unprocessed meats. Processed meats are smoked, cured, salted, or have chemical preservatives added. Examples include hot dogs, salami, sausages, and deli meats. Just 1.8 oz. (about one hot dog) daily drastically increases the risk of heart disease.
Hot Dogs and Diabetes
Another study, reported on NPR, found that those that eat red meat more than three times per week were 50 percent more likely to develop Type 2 diabetes. Even when researchers accounted for weight gain, the percentage was the same. It’s thought that eating too much red meat puts your system into iron overload, which sets the stage for insulin resistance.
And then there are the nitrosamines, also found in hot dogs.
"Our understanding is that, especially [when they occur in] processed meats, these nitrosamines can cause inflammation," explains Dr. David Nathan, who directs the diabetes center at Massachusetts General Hospital.
Nitrosamines can also poison the cells that make insulin (beta cells in the pancreas), creating resistance.
Organic Isn’t Always Better
Organic hot dogs aren’t always better, even those that claim to be free of nitrates and nitrites, which have been linked to cancer. Nitrates and nitrites are used to kill bacteria, especially the infamous botulism.
Conventional hot dogs use sodium nitrate, the synthetic version of the additive, while organic and natural hot dogs use celery juice or celery salt. A study published in The Journal of Food Protection found that natural hot dogs had anywhere from one half to 10 times the amount of nitrates found in conventional hot dogs. So they’re definitely not nitrite-free.

According to my article on TreeHugger, “Current labeling standards require products that use the non-synthetic source of nitrites and nitrates to say "Uncured" or "No nitrates or nitrites added," when products are cured and nitrites and nitrates are added, just from a natural source.”
[Editor's Note: If you're looking for a better-for-you hot dog made from 100% real beef, we recommend Applegate. Their hot dogs are made with grass-fed beef, and do not contain antibiotics or growth hormones. Their hot dogs do contain celery powder (which contain naturally-occurring nitrites) but if you're in the mood for a hot dog, this is a cleaner option.]
