Eating ultra-processed foods is associated with a significantly higher risk of developing cancer, diabetes, and cardiovascular diseases, according to a major study published in the medical journal Family Medicine and Community Health.
Researchers found that consuming an extra 100 grams of ultra-processed food each day is linked to a 14 percent higher risk of cardiovascular disease and a four percent higher risk of cancer.
The same daily 100-gram increase in ultra-processed food intake was also tied to a two percent increase in the risk of diabetes and metabolic syndrome, alongside a three percent higher risk of death from any cause.
The findings stem from a massive meta-analysis that combined results from 51 separate studies. In total, the research monitored the health of more than 8.8 million participants over observation periods lasting anywhere from two to 32 years.
Broad health risks identified
When analyzing overall high consumption of ultra-processed foods, scientists identified substantial risk increases across multiple major health conditions. High consumption was linked to a 24 percent higher risk of cardiovascular disease, a 12 percent higher risk of cancer, and a 23 percent increase in the risk of obesity and overweight status.
Cardiovascular diseases encompass conditions affecting the heart and blood vessels, such as coronary heart disease and stroke, which are leading causes of medical complications globally.
The analysis further revealed that individuals with high ultra-processed food intake faced a 24 percent higher risk of developing diabetes and metabolic syndrome. Diseases of the digestive system were 31 percent more common in high consumers, while the overall risk of death from any cause rose by 18 percent.
Ultra-processed foods are defined as products that undergo intensive industrial processing and frequently contain high levels of salt, sugar, and various additives. In modern food manufacturing, these items commonly include mass-produced snacks, packaged baked goods, carbonated soft drinks, sugary breakfast cereals, and frozen ready meals.
Study limitations and earlier findings
The authors of the report noted that the study demonstrates a statistical association and does not prove that ultra-processed foods directly cause these diseases. Observational meta-analyses combine data from multiple population groups to highlight overall trends, but cannot establish direct cause-and-effect mechanisms on their own.
Family Medicine and Community Health is an international peer-reviewed journal dedicated to primary care, preventive medicine, and community health research. Metabolic syndrome, one of the conditions evaluated in the meta-analysis, is a cluster of risk factors including high blood pressure, high blood sugar, excess abdominal fat, and abnormal cholesterol levels.
The report builds on a growing body of scientific investigation into how specific dietary components influence chronic disease outcomes. In an earlier study, scientists determined that the consumption of soybean oil was linked to an increased risk of developing bladder cancer.
