New research reveals that regular takeaway consumption can increase biological age and reduce the health benefits of exercise

A recent study conducted by researchers at Peking University’s Third Hospital in China has found that regularly eating takeaway food could accelerate biological ageing, potentially shortening your lifespan. The study, published in BMC Medicine, reveals that individuals who frequently consumed takeaway meals had a biological age approximately three months older than those who cooked at home. This finding was based on blood test results from a sample of 43,000 adults in the UK.

The study found that people who regularly indulged in takeaway food had a faster rate of liver, kidney, and immune system deterioration compared to their peers who cooked at home. This effect, researchers say, can negate the positive effects of exercise, highlighting a disturbing trend where unhealthy eating habits can undo the benefits of physical activity.

The effects on health were particularly pronounced for individuals with weight gain and obesity, but even those who were not overweight experienced a noticeable decline in health. Researchers pointed to the high calorie, fat, salt, and sugar content of takeaway meals, which often lack important nutrients like fibre and vitamins. Additionally, takeaways are often consumed quickly and alone, leading to less mindful eating practices and the likelihood of overeating.

The study also cited potential harm from plastic packaging, which may contain harmful chemicals such as PFAS. These chemicals, along with poor dietary choices, could contribute to gut imbalances and inflammation, raising the risk of chronic conditions like type 2 diabetes and heart disease.

Dr Nan Li, one of the lead researchers, explained: “Framing the effects in terms of accelerated ageing and demonstrating that regular consumption cancels out the benefits of exercise provides a behavioural nudge for consumers.” The study suggests that the long-term impact of frequent takeaway consumption could be significant, contributing to a 2.2% to 2.7% increase in mortality risk, comparable to the severe effects of smoking.

While the study raises concerns about the health impacts of takeaways, it also underscores the importance of balanced diets and mindful eating. Despite the health risks associated with regular takeaway consumption, some figures within the food industry have defended certain traditional meals, such as fish and chips, which are considered high in protein and nutrients. Andrew Cook, president of the National Federation of Fish Friers, argued that fish and chips, enjoyed as part of British tradition, are still a healthier option compared to other ultra-processed foods.

As takeaway meals continue to grow in popularity, especially with busy modern lifestyles, the study serves as a stark reminder of the importance of maintaining a healthy, balanced diet. It also highlights the need for greater awareness around the long-term health risks of seemingly convenient but nutritionally poor food choices.
