Ultra-Processed Foods Accelerate Aging
A new report in New Scientist warns that ultra-processed foods may not only contribute to chronic health problems but could also accelerate aging. The commentary adds another dimension to the growing body of evidence linking highly processed foods to poor health outcomes and suggests that diet quality may play a role in the biological aging process.
- One study found that for every 10% increase in the consumption of ultra-processed foods, the gap between a person's biological and chronological age increased by 2.4 months. - Research has linked high consumption of ultra-processed foods—more than three servings a day—to a doubled likelihood of having shorter telomeres, which are sections of chromosomes that serve as a marker for biological age. - Ultra-processed foods are industrial formulations that often contain substances not typically used in home cooking, such as artificial colorings, flavorings, emulsifiers, and preservatives. Examples include packaged snacks, sodas, instant noodles, and many ready-to-eat meals. - The association between a diet high in ultra-processed foods and accelerated aging may be influenced by factors beyond poor nutritional quality. These can include the effects of chemical additives on inflammation, the breakdown of the food's natural structure during processing, and exposure to chemicals from packaging like bisphenol A (BPA). - Food additives like emulsifiers, commonly found in ultra-processed foods to improve texture and extend shelf life, may disrupt the gut microbiome and promote inflammation, which can contribute to the aging process. - Ultra-processed foods now account for nearly 60% of the calories consumed by adults in the United States and almost 70% for American children.
