High blood sugar levels in midlife increase the risk of developing Alzheimer’s disease, according to a study published in Alzheimers & Dementia. In 4,932 participants from the Framingham Heart Study, high blood sugar levels measured as young as age 35 were associated with an almost 15% increased risk of dementia decades later. These results may help explain why vegan diets, which are associated with greatly reduced risk of diabetes, are also associated with reduced risk of cognitive decline.
