A large-scale analysis of 51 studies involving nearly 9 million people found that higher consumption of ultra-processed foods is associated with increased risks of chronic disease and early death.

A new study has identified a link between the consumption of ultra-processed foods (UPFs) and a higher risk of chronic health conditions and early death. Researchers analyzed 51 studies involving nearly 9 million participants globally to examine the relationship between UPF intake and health outcomes. The findings suggest that higher consumption of these foods, which are often high in sugar, salt, and unhealthy fats, correlates with an increased risk of developing multiple diseases.

Study Methodology and Findings

The researchers utilized the NOVA classification system to define ultra-processed foods as industrial formulations containing five or more ingredients, often including substances not typically used in home cooking. The analysis included adults aged 18 or older and tracked participants over periods ranging from 2 to 32 years. The study found that increasing UPF intake by 10% of total daily food consumption was linked to a 16% higher risk of metabolic syndrome or diabetes. Additionally, dose-response analysis indicated an 11% higher risk of high blood pressure for every 100 grams of UPFs consumed daily.

Expert Recommendations for Dietary Changes

Nutrition experts suggest that while eliminating all ultra-processed foods may not be necessary, they should not form the foundation of a diet. Registered dietitian Johannah Katz noted that the research indicates a dose-response relationship, where higher intake correlates with higher risk. Dietitian and chef Vahista Ussery recommends a gradual approach to reducing intake, such as swapping processed items for healthier versions, cooking more meals at home using whole ingredients, and reducing fast food consumption.
