A prominent physician has explained why many people experience a dip in concentration and energy shortly after lunch, commonly known as brain fog. Dr Mark Hyman, who regularly shares health advice with millions of social media followers, said the condition is linked to ultra-processed foods.
Dr Hyman noted that brain fog by 2pm, bloating after meals, aching joints, and skin breakouts are all signs of chronic inflammation caused by diet. 'Ultra-processed food created this, real food can reverse it,' he stated. He explained that while acute inflammation is a normal immune response, chronic inflammation triggered by poor diet can lead to fatigue, brain fog, and other health issues.
Ultra-processed foods (UPFs) are high in refined grains, added sugars, and unhealthy fats. Research indicates that UK adults derive roughly 53-57 per cent of daily calories from UPFs, slightly less than the 55-60 per cent seen in the US. These foods have been linked to heart disease, cancer, type 2 diabetes, and premature death.
A study published in the British Medical Journal found that greater exposure to UPFs was associated with a higher risk of adverse health outcomes, including cardiometabolic diseases and mental disorders. Another study estimated that 14 per cent of early deaths in the UK could be attributable to ultra-processed food intake.
