Dementia risk rises from ultra-processed food consumption

It is well known that ultra-processed foods (UPF) negatively impact physical health. However, new research provides stronger evidence that this dietary pattern also significantly harms brain health. A study published in Alzheimer’s and Dementia by the Alzheimer’s Association reveals UPF linked to over 30 adverse health effects, including key dementia risk factors such as cardiovascular disease, type 2 diabetes, and obesity. Researchers at Australia’s Monash University analysed over 2,000 dementia-free Australians aged 40-70, comparing their diets with cognitive function. Surprisingly, a 10% increase in UPF intake correlated with lower attention scores and higher dementia risk—consistent even among those following healthy diets like the Mediterranean diet. Dr. Daniel Amen, a psychiatrist and founder of Amen Clinics, explained that the brain is a highly energy-hungry organ. ‘The brain uses around 20% of your consumed calories, so the quality of those calories is crucial,’ he said. According to Dr. Amen, food can be medicine or poison. Ultra-processed items like packaged snacks, soft drinks, and ready meals are high in sugar, unhealthy fats, and artificial additives. ‘Attention is the gateway to learning, memory, decision-making, and problem-solving. If you cannot focus, you cannot fully absorb information,’ he added. Though the self-reported data has limitations, researchers stress the need for improved global dietary guidelines. Dr. Amen advises a simple principle: ‘Love foods that love you back.’ He recommends shifting from factory-made foods to whole foods grown from plants. For those with family histories of dementia, diabetes, or hypertension, dietary intervention is no longer a secondary option but a primary strategy for brain health. ‘You are not stuck with the brain you have now. You can improve it, starting with the next bite,’ he concluded. (Fox/I-2)
