Think twice before reaching for that fizzy can of Coke or biting into a hot dog. According to a groundbreaking study by the University of Michigan, popular ultra-processed foods may be silently stealing minutes if not years from your life.
The study presents startling evidence: consuming a single hot dog could shorten your life by 36 minutes, while drinking a can of Coke might cost you 12 minutes. Other everyday comfort foods don’t fare much better. Breakfast sandwiches and eggs were linked to a 13-minute reduction in lifespan each, cheeseburgers cost 9 minutes, and bacon trimmed off another 6 minutes.
These calculations were made by analysing the nutritional profile and health risks associated with over 5,800 foods, combining data on disease burden, nutrition, and environmental impact. The result: a chilling reminder that modern diets built around convenience and taste may be taking a toll on our health in very real terms.
Ultra-processed foods (UPFs) are industrially manufactured products loaded with refined sugars, salts, fats, preservatives, and artificial additives. They’re designed for convenience and mass consumption but are increasingly under scrutiny for their role in chronic diseases.
In recent years, mounting scientific evidence has tied high UPF consumption to an alarming array of health risks. Earlier this year, the British Medical Journal published a study showing that frequent consumption of UPFs is linked to a 50 per cent higher risk of cardiovascular-related death.
The same study also found:
- 48–53 per cent increased risk of mental health issues, including anxiety and depression.
- 12 per cent higher risk of developing type 2 diabetes.
- Up to 66 per cent greater risk of heart disease.
These findings reinforce the long-standing concerns of nutritionists and public health experts who have warned about the cumulative and long-term damage inflicted by the Western diet — a diet increasingly replicated across the globe.
There’s a silver lining. The University of Michigan study also identified certain foods that add time to your life. For instance, eating nutrient-rich fish could add up to 32 minutes per serving to your lifespan. Other healthy whole foods, including some varieties of fruits, vegetables, nuts, and legumes, also contribute positively to life expectancy.
Surprisingly, certain cheeses like cheddar and brie, often vilified for their fat content, may also support longevity. These fermented dairy products have shown protective benefits against diseases like liver cancer, possibly due to their unique microbial and biochemical compositions.
Coca-Cola, long synonymous with refreshment, is now emblematic of the health crisis linked to sugary beverages. One can of Coke contains around 39 grams of sugar, exceeding the daily recommended limit for both men and women as set by the American Heart Association.
High sugar intake is directly linked to obesity, insulin resistance, and metabolic syndrome, all of which are precursors to life-threatening diseases like diabetes and heart failure. The 12-minute reduction in life expectancy linked to Coke is not just theoretical — it represents a statistical estimate of the disease burden that such sugar-laden beverages place on the human body.
The real danger may lie in how normalized ultra-processed food has become. Hot dogs, breakfast sandwiches, sodas, and cheeseburgers are often marketed as affordable and time-saving solutions — especially for low-income or fast-paced urban populations. But the hidden costs, measured in minutes of lost life and higher healthcare burdens, are staggering.
Public health experts warn that the long-term implications of UPF dependency go beyond individual health. They’re reshaping entire societies, fueling the rise of non-communicable diseases (NCDs) that now account for 74 per cent of all global deaths, according to the WHO.
