Lower abdominal fat linked to better brain health

A recent study suggests that abdominal fat and diet quality during middle age may impact brain health in older age. Researchers found that a low waist-to-hip ratio (WHR) could lead to better brain connectivity. Conversely, a high WHR may harm significant brain areas, particularly 25% of white matter tracts. White matter is crucial for communication within the brain and between the brain and spinal cord. Keeping our brains healthy as we age is important for maintaining independence and quality of life. Research shows the brain can start changing decades before dementia symptoms appear, making healthy habits vital at any age. The study analyzed data from a long-term project in the UK called the Whitehall II Study, which began in 1985 and involved over 10,000 participants. Researchers focused on two groups: one that assessed diet quality and another that measured WHR. They found that better diets and lower WHR were linked to improved brain function and memory later in life. In contrast, higher abdominal fat correlated with poorer cognitive abilities in older age. Researchers used functional brain MRI scans to assess brain activity and connectivity. They discovered that individuals with higher WHR had increased widespread damage to white matter. Diet plays a significant role in brain health. A balanced diet, such as the MIND diet, may be beneficial. This diet incorporates various nutritious foods and is adaptable to personal preferences. Other healthy habits, like exercise, sleep, and reducing stress, can support brain health too. The study highlights the importance of maintaining a healthy weight and diet during middle age to support cognitive function later in life. While more research is needed, small lifestyle changes can have lasting benefits for brain health. Simple steps, like cooking healthier meals or reducing screen time before bed, might lead to significant improvements over time.
