UK Study Links Ultra-Processed Foods to Heart Disease and Diabetes

LONDON: (News Desk) – Excessive consumption of ultra-processed foods may significantly increase the risk of developing heart disease and type 2 diabetes, according to a new study conducted in the United Kingdom.

The research, jointly carried out by University College London and Imperial College London, found that eating ultra-processed foods triggers chemical changes in the bloodstream that may contribute to the development of chronic diseases.

Ultra-processed foods undergo several stages of industrial processing and generally contain high amounts of salt, sugar and artificial additives. They also tend to have low nutritional value, particularly in essential nutrients such as dietary fibre.

Common examples include fast food, packaged bread, sweets, candies, cakes, savoury snacks, breakfast cereals, chicken and fish nuggets, instant noodles, sugary beverages and soft drinks.

For the study, researchers analysed health and dietary information from more than 6,000 individuals. The data was originally collected during the 1980s, when participants’ eating habits were documented. Their health was subsequently monitored for more than two decades.

The research focused on metabolites, which are small molecules found in the blood and play an important role in food metabolism and various chemical processes within the body.

Scientists examined 233 blood molecules and used machine learning technology to identify metabolites associated with different dietary patterns.

The findings indicated that blood molecules linked to ultra-processed food consumption contained higher levels of unhealthy fats and lower levels of beneficial fats, including omega-3 fatty acids. In comparison, diets consisting of minimally processed foods were associated with a healthier metabolic profile.

According to the research, higher consumption of ultra-processed foods was associated with an increased risk of heart disease of up to 17 per cent.

In contrast, consuming minimally processed foods was linked to a 17 per cent lower risk of heart disease and a reduction of up to 40 per cent in the risk of developing type 2 diabetes.

Researchers explained that elevated levels of metabolites associated with ultra-processed foods were linked to a greater likelihood of developing these chronic conditions.

Although the precise biological mechanisms remain unclear, scientists believe changes in gut bacteria and increased inflammation in the body could play a significant role.

The researchers described the study as the first to investigate the metabolic changes associated with ultra-processed food consumption.

However, they emphasised that further research is necessary to validate the findings and better understand how these dietary patterns contribute to long-term health risks.
