'Ultra-Processed' Junk Food Linked to Advanced Ageing at Cellular Level, Study Finds
People who eat a lot of industrially processed junk food are more likely to exhibit a change in their chromosomes linked to ageing, according to research presented Tuesday at an online medical conference.
Three or more servings of so-called "ultra-processed food" per day doubled the odds that strands of DNA and proteins called telomeres, found on the end of chromosomes, would be shorter compared to people who rarely consumed such foods, scientists reported at the European and International Conference on Obesity.

Earlier studies had pointed to a possible link with sugar-sweetened drinks, processed meats, and other foods loaded with saturated fats and sugar, but the findings were inconclusive.
Ultra-processed foods are industrially manufactured substances composed of some mix of oils, fats, sugars, starch, and proteins that contain little if any whole or natural foods.
They often include artificial flavourings, colourings, emulsifiers, preservatives, and other additives that increase shelf-life and profit margins.
These same properties, however, also mean that such foods are nutritionally poor compared to less processed alternatives, the researchers said.
Earlier studies have shown strong correlations between ultra-processed foods and hypertension, obesity, depression, type 2 diabetes, and some forms of cancer.
These conditions are often age-related in so far as they are linked to oxidative stress and inflammation known to influence telomere length.
