Unprocessed Carbs Linked to Lower Dementia Risk.
Using data from the UK Biobank study, researchers report that a diet rich in fruits, legumes, and whole grains was associated with a 16% lower risk of Alzheimer’s disease, whereas a high intake of ultra-processed carbohydrates was linked to a 14% higher risk of the neurodegenerative condition. These findings suggest that diets emphasizing slower-digesting carbohydrates that minimize blood glucose spikes may help support brain health and reduce dementia risk as part of broader healthy aging strategies.
