Can Eating Hot Dogs Shave Years Off a Healthy Life?

Every bite we take could be a countdown — or a boost — to our longevity. What if your favorite guilty pleasure, the humble hot dog, was silently shaving minutes off your life? A groundbreaking study from the University of Michigan doesn’t just warn against certain foods — it quantifies their impact. And the results may make you think twice about that next ballpark bite. How much of your life are you trading for a tasty snack?

Key Takeaways

• Hot Dogs Take Time Off Your Life: A single beef hot dog on a bun can cost you 36 minutes of healthy life, according to the Health Nutritional Index (HENI).

• HENI Helps Rank Food Choices: The Health Nutritional Index evaluates foods based on beneficial and harmful nutritional factors, giving a life-minutes score per serving.

• Small Changes, Big Impact: Swapping just 10% of daily calories from processed meats with plant-based and seafood options could extend healthy life by 48 minutes per day.

America’s Favorite Foods, Ranked by How Much They Shorten (or Extend) Your Life

The National Hot Dog and Sausage Council estimates that Americans consume approximately 20 billion hot dogs annually. If you’re one of these hot dog lovers, you might reconsider regular consumption of these ballpark treats.

A new study from the University of Michigan finds that if you consume hot dogs regularly, then you’ll spend more time suffering from physical disabilities as you age. Let’s take a closer look at why you should avoid hot dogs and what foods you should eat instead.

There’s a big problem with dietary recommendations: It’s easy to say, “don’t eat this” or “eat this” for good health. Nutrition researchers believe this approach doesn’t always result in healthy eating habits. To make dietary recommendations easier and more meaningful to people, the University of Michigan research team developed a new system. It's called the Health Nutritional Index (HENI).

HENI is designed to shed light on the hidden health risks and benefits of foods and to translate complex nutritional information into a simple but meaningful score that people can use as they plan their meals.

Nearly 6000 Foods Analyzed—Including Hot Dogs 

The index is adapted from the Global Burden of Disease a comprehensive global database analyzing 286 causes of death and 369 diseases and injuries. It also determines the risks and benefits of multiple factors, including 15 dietary ones.

To create HENI the research team adapted their findings to see how many minutes of life are lost or gained per serving size of each of 5,853 foods in the ordinary U.S. diet.

Researchers examined foods that are considered healthy such as milk, nuts and seeds, fruits, calcium, omega-3 fatty acids from seafood, fibers (from fruits, vegetables, legumes, and whole grains,) and polyunsaturated fatty acids (PUFAs). They also examined foods that are not considered healthy, including processed meat, red meat, trans fatty acids (TFAs), sugar-sweetened beverages, and salt.

To determine the health value of a food, they looked at the nutritional factors considered beneficial and detrimental and then did some complex math to provide an index rating.

For instance, a three-ounce serving of chicken wings contains, in their view, four significant components affecting health - calcium and PUFAs on the plus side, salt and TFAs on the minus side.

The overall rating for chicken wings was found to be negative, with a HENI rating of 3.3 minutes of healthy life lost per serving. Other examples of minutes lost include:

• A beef hot dog on a bun: 36 minutes of healthy life lost.

• Vegetable pizza: 1.4 minutes of healthy life lost.

• Corned beef with tomato sauce and onion: 71 minutes of healthy life lost.

• A soft drink: 12.5 minutes of healthy life lost.

Foods where minutes are gained include:

• Apple pie:1.3 minutes of healthy life gained.

• Baked salmon: 16 minutes of healthy life gained.

• Peanut butter and jam sandwiches: 33 minutes of healthy life gained.

• Sardines with a tomato-based sauce: 82 minutes of healthy life gained.

Enjoy a Big Health Impact From Small, Targeted Changes 

The researchers wrote, "Interestingly, our results offer unambiguous and generalizable inferences for only a few food categories.

"HENI scores for frankfurter (hot dog or sausage) and breakfast sandwiches, burgers, and red meat are almost exclusively negative, indicating that eating an additional serving of these foods is health-damaging.

"On the other hand, increasing the consumption of nuts and of peanut butter and jelly sandwiches (driven by nut content), legumes, seafood, fruits, snack bars, ready-to-eat cereals, and non-starchy vegetables, is health beneficial as most of these foods have positive HENI scores."

The researchers were encouraged to see that small, targeted changes can make a meaningful difference - no dramatic shifts in diet are required.

Substituting just ten percent of daily calories from beef and processed meats for a diverse mix of whole grains, fruits, vegetables, nuts, legumes, and selected seafood could offer substantial improvements to your health and add 48 minutes of healthy life per day.

Summary

A new University of Michigan study introduces the Health Nutritional Index (HENI), a system that assigns a value to foods based on how many minutes of healthy life they add or subtract. By analyzing nearly 6,000 foods, researchers found some everyday favorites, like hot dogs and sugary drinks, significantly reduce healthy lifespan, while others — like baked salmon and PB&J sandwiches — may increase it. The study shows that even small, mindful dietary changes can have a substantial impact, adding nearly an hour of healthy life each day by replacing processed meats with plant-based alternatives and seafood.

Frequently Asked Questions 

What is the Health Nutritional Index (HENI)?

HENI is a food ranking system developed by University of Michigan researchers that calculates how many minutes of healthy life are gained or lost per serving of food.

How does HENI determine the health value of food?

It evaluates nutritional pros (like fiber, calcium, omega-3s) and cons (like trans fats, sodium, sugar) to estimate a time-based health score.

What foods cost the most minutes of life?

Corned beef (71 minutes lost), hot dogs (36 minutes lost), and soft drinks (12.5 minutes lost) ranked among the worst.

What foods add healthy time to your life?

Sardines in tomato sauce (82 minutes gained), peanut butter & jelly sandwiches (33 minutes), and baked salmon (16 minutes) scored highly.

How can I improve my diet without major changes?

Replace 10% of your daily calories from processed meat with fruits, legumes, seafood, and whole grains to gain up to 48 minutes of healthy life per day.
