Ultra-Processed Foods Accelerate Aging
A new analysis reveals that ultra-processed foods might speed up the aging process beyond just raising chronic disease risks. The study links high intake of foods with additives, preservatives, and refined ingredients to biological markers of accelerated aging. A separate study comparing five popular diets found that patterns emphasizing vegetables, fruits, whole grains, and nuts can add years to your life.
- A Monash University-led study found that for every 10% increase in the consumption of ultra-processed foods (UPFs), the gap between a person's biological and chronological age increased by 2.4 months. - The accelerated aging effect of UPFs may not be solely due to their poor nutritional content; researchers suggest that "non-nutrient characteristics" like harmful substances formed during processing and contact with unhealthy packaging materials could be significant contributing factors. - Biological aging was assessed in one study using the PhenoAge algorithm, which analyzes 36 different blood biomarkers to determine a person's biological age rather than just their chronological age. - Common examples of ultra-processed foods include packaged snacks, sugary drinks, ready-to-eat meals, processed meats like sausages and burgers, and even some mass-produced breads and fruit yogurts. - Earlier research has also linked the consumption of UPFs to other markers of aging, such as the shortening of telomeres, which are the protective caps on the ends of chromosomes. - The term "ultra-processed food" comes from the NOVA classification system, developed by Brazilian researchers, which categorizes foods based on their level of industrial processing. - Beyond accelerated aging, high consumption of ultra-processed foods is associated with increased risks for chronic inflammation, heart disease, type 2 diabetes, and obesity. - An Italian study involving over 22,000 adults found that individuals with the highest consumption of ultra-processed foods were biologically older by an average of 0.34 years compared to those with the lowest consumption.
