12 Aug 2013 - FoodNavigator - Blood sugar status may affect risk of dementia

By Nathan Gray

High blood glucose levels may increase the risk of developing dementia, according to a new study.

FAB RESEARCH COMMENT:

See Crane et al 2013 - Glucose levels and risk of dementia

This large-scale study adds to the now quite substantial evidence linking diabetes with dementia risk (see Food for Thought: Eat Your Way to Dementia - Sugar and Carbs Cause Alzheimer's Disease)

However, this latest study takes the link between higher blood glucose and dementia risk into the general population, because the results indicated that higher blood glucose levels may be a risk factor for dementia even among persons without diabetes.

Writing in the New England Journal of Medicine, researchers from the USA reveal that people who have high blood sugar levels over a long period of time may be at a higher risk of developing dementia.

Led by Professor Paul Crane, from the University of Washington, the research team averaged yearly blood sugar levels of more than 2000 people for 5 years before tracking their later incidence of dementia.

'The most interesting finding was that every incrementally higher glucose level was associated with a higher risk of dementia in people who did not have diabetes' explained Crane. 'There was no threshold value for lower glucose levels where risk levelled off'.
