Chocolate might decelerate the ageing process and support longer and healthier lifespans, according to researchers. But before you grab that bar of Dairy Milk and begin indulging, it’s a specific variety of chocolate that could potentially slow down ageing: dark chocolate.
Experts at King’s College London suggest a crucial compound present in dark chocolate might reduce the pace of biological ageing. They claim the chemical theobromine, a widespread plant substance derived from cocoa, could possess anti-ageing qualities.

Research published in the Aging journal saw scientists examine theobromine concentrations in participants’ blood alongside blood-based indicators of biological ageing, reports the Mirror. Biological age reflects how old your body appears based on wellness and performance, rather than chronological years lived. You could be 45 chronologically whilst maintaining a biological age of 35, for instance.
Researchers analysed over 1,600 individuals and discovered those with elevated theobromine levels in their bloodstream possessed a biological age lower than their chronological age. Professor Jordana Bell, the study’s senior author and epigenomics professor at King’s College London, explained: “Our study finds links between a key component of dark chocolate and staying younger for longer. While we’re not saying that people should eat more dark chocolate, this research can help us understand how everyday foods may hold clues to healthier, longer lives.”
The researchers also examined whether compounds found in cocoa and coffee demonstrated a comparable connection, but disappointingly discovered that the benefit appeared to be unique to theobromine, which hasn’t been extensively studied scientifically but is recognised for its toxicity to dogs.
Dr Ramy Saad, principal investigator at King’s College London and a clinical genetics specialist, commented: “This is a very exciting finding and… could lead us to important discoveries towards ageing, and beyond, in common and rare diseases.”
Is dark chocolate beneficial for your health?
Dark chocolate boasts established health advantages that may help lower your chances of developing serious conditions such as heart disease, dementia and cancer. It ranks amongst the finest sources of antioxidants, can assist in reducing cholesterol levels, enhance circulation and cognitive function, and provides a valuable source of fibre and beneficial fats.
Nevertheless, simply because a product is labelled as “dark chocolate” doesn’t automatically render it nutritious, and you should always examine the label for ingredients and cocoa percentage. Professor Tim Spector from the science and nutrition company Zoe recommends selecting a bar containing at least 70% cocoa.
