PARIS - 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 on Tuesday at an online medical conference.
While the correlation is strong, however, the causal relationship between eating highly processed foods and diminished telomeres remains speculative, the authors cautioned.Telomeres do not carry genetic information, but are vital for preserving the stability and integrity of chromosomes and, by extension, the DNA that all the cells in our body relies on to function.
They often include artificial flavourings, colourings, emulsifiers, preservatives and other additives that increase shelf-life and profit margins. These conditions are often age-related in so far as they are linked to oxidative stress and inflammation known to influence telomere length. Those in the high-intake group were more likely to have a family history of cardiovascular disease, diabetes and abnormal blood fats.
