Key takeaway:
- Regular hot dog consumption is linked to higher risks of cancer, heart disease, and high blood pressure due to processed meat ingredients.
- Health experts recommend eating hot dogs only occasionally and choosing products with simpler ingredient lists.
- Many Americans remain unaware of the health risks despite hot dogs being a popular summer food.
Health experts are urging that hot dog consumption be limited to only occasional indulgence this summer, warning that processed meats contain ingredients linked to higher risks of cancer, heart disease, and high blood pressure, even though they remain a popular choice for cookouts and holiday celebrations.
Hot dog consumption remains a staple at backyard barbecues, sporting events, and Fourth of July gatherings across the United States. Nutrition experts say its convenience and flavor help explain the popularity, but they caution that regular hot dog consumption carries significant health risks.
“Americans like them because they are convenient and easy, and hyper-palatable because they taste salty and fatty,” said Julia Zumpano, a registered dietitian at the Cleveland Clinic. “We get a big cascade of pleasure eating them. They hit the pleasure centers in our brains. It’s hard to not eat them, and it’s hard to stop eating them.”
Medical experts also warn against competitive hot dog eating contests held during Independence Day celebrations. Rapid overconsumption can cause serious medical emergencies, including ruptures of the esophagus, gastrointestinal injuries, and, in severe cases, sepsis.
According to a recent survey, more than half of Americans said they eat hot dogs regularly, while nearly 90% reported they were unaware of the potential health risks associated with frequent consumption.
The U.S. Department of Agriculture defines hot dogs, also known as frankfurters, as cooked or smoked sausages made from one or more types of livestock muscle under federal food standards. Many products also contain mechanically separated poultry or pork, organ meats, and casings made from collagen or animal intestines.
Health specialists say one of the biggest concerns is the use of nitrates and nitrites as preservatives in processed meats. These compounds can form nitrosamines during digestion, substances that research has linked to increased risks of stomach, colorectal, and esophageal cancers.
Hot dog consumption also involves relatively high nitrate levels compared with other processed meats. A typical serving contains about 9 milligrams of nitrates, compared with approximately 5.5 milligrams in bacon and about 1 milligram in cured ham.
“Are hot dogs harmful? Are you kidding me?” said Michael Jacobson, a food scientist and retired executive director of the Center for Science in the Public Interest. “They are among the worst foods you can eat if you eat them often. Once in a while is OK, but eating them regularly is a very bad idea.”
Nutrition experts also point to the high sodium content found in many hot dogs. Excess sodium intake is associated with elevated blood pressure and greater risks of heart disease, stroke, heart failure, and kidney disease.
“Processed meats contain other additives and are very high in sodium, which is a well-established risk factor for high blood pressure and heart disease,” said Dr. Walter Willett, professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health.
For consumers who still choose to eat hot dogs, food experts recommend selecting products with shorter ingredient lists and avoiding fillers such as mechanically separated meat, corn starch, and soy ingredients.
“When I’m buying hot dogs, I look for all-beef brands and always flip the package around to check for filler,” said chef Kathleen Boureston, owner of the food blog Gonna Want Seconds. “You want minimal ingredients included.”
Food reviewers have highlighted several premium beef hot dogs with simpler ingredient lists, but nutrition experts stress that moderation remains the most effective way to reduce health risks associated with processed meats.
