Ultraprocessed Foods Linked to Reduced Lifespan, New Study Reveals
High intake of ultraprocessed items may decrease longevity by over 10%, researchers find.

Overview of the Study
A new, extensive study involving over 500,000 participants has revealed that consuming high levels of ultraprocessed foods can significantly reduce lifespan by more than 10%. Conducted over nearly three decades, the research found that men faced a 15% increased risk, while women saw a 14% rise in health issues related to their diet. The study's lead author, Erikka Loftfield from the National Cancer Institute, emphasized the strong link between ultraprocessed food intake and overall health.
Key Contributors to Ultraprocessed Consumption
Participants in the study who were among the top 10% for ultraprocessed food consumption primarily relied on processed beverages. Diet soft drinks were identified as the main contributor, followed closely by sugary soft drinks. Additionally, refined grains found in products like ultraprocessed breads and baked goods ranked high in popularity. These findings highlight the significant role that beverages and refined grains play in the average diet.
Understanding the NOVA Classification
The study utilized the NOVA food classification system, developed by nutrition expert Carlos Monteiro. This system categorizes foods based on their level of processing, ranging from unprocessed or minimally processed foods like fruits and vegetables to ultraprocessed items such as deli meats and sausages. Ultraprocessed foods often contain additives and ingredients not typically used in home kitchens, designed to enhance flavor and appeal.
Health Risks Associated with Ultraprocessed Foods
High consumption of ultraprocessed foods has been linked to various health issues, including cardiovascular disease and type 2 diabetes. Specific items like processed meats and soft drinks were found to carry higher risks. Diet beverages, containing artificial sweeteners, have also been connected to increased chances of experiencing serious health problems. Reducing intake of these foods is recommended to maintain better overall health.
Study Limitations and Dietary Trends
One limitation of the study was that dietary data was collected only once, nearly 30 years ago, making it difficult to account for changes in eating habits over time. Since then, the prevalence of ultraprocessed foods in diets has likely increased, with estimates suggesting that up to 60% of daily calories now come from such foods. This rise underscores the growing importance of understanding the long-term impacts of diet on health.
Conclusion
The findings from this large-scale study emphasize the importance of limiting ultraprocessed food intake to enhance longevity and reduce the risk of serious health conditions. Experts advocate for a diet rich in whole, minimally processed foods, encouraging individuals to make informed choices by reading nutrition labels. By focusing on healthier eating habits, it is possible to improve quality of life and promote better overall well-being.
