Drinking decaffeinated coffee could help to preserve memory function, according to a recent study. By improving the brain energy metabolism associated with Type 2 diabetes, decaffeinated coffee could stave off the memory loss associated with dementia and other neurodegenerative disorders, researchers from Mount Sinai School of Medicine claim. Scientists made the discovery when investigating if dietary supplements with a standardised decaffeinated coffee preparation prior to diabetes onset might improve insulin resistance and glucose utilisation. They identified that the brain was able to more effectively metabolize glucose and use it for cellular energy in the brain when exposed to decaffeinated coffee. Low levels of glucose in patients with Type 2 diabetes is known to cause dementia and other neurocognitive problems. Depression is also believed to increase the chance of a patient with diabetes developing dementia. People with diabetes who have depression are twice as likely to develop dementia than those who only have diabetes, according to a study at the University of Washington.
