The study found that people who drink large amounts of the sugary drinks in question have shorter telomeres, the ends of the cell's chromosomes, in their white blood cells. Previous research has already shown a link between telomere length and lifespan, and shorter telomeres are associated with tissue damage, inflammation, insulin resistance and chronic diseases such as diabetes.
The consumption of sugary drinks is enormous, especially in the United States, with as many as 50% of Americans consuming these beverages. Approximately one in four have an intake of at least 200 calories and a full 5% have an intake of at least 567 calories thanks to sugary drinks.
The aforementioned study involved 5309 people aged 20-65 who had never suffered from diabetes or cardiovascular disease in the past. The average consumption of sugary drinks among these people was about 360g, however, a full 21 percent of the participants reported drinking at least 560g every day. As part of the study, the participants had their DNA examined and their telomeres measured, and there was a very clear link between telomere length and the amount of sugary drinks they drank. The calculation at the conclusion of the study is staggering - consuming 560g of sugary drinks per day is associated with approximately 4.6 years of biological ageing.
