Decaffeinated coffee could prevent memory loss and associated problems for patients with type 2 diabetes, a new study has claimed. The research, carried out at Mount Sinai School of Medicine and published in the journal Nutritional Neuroscience, showed that decaff coffee could help to improve the brain energy metabolism linked with type 2 diabetes, as well as being a risk factor for dementia and conditions such as Alzheimers disease .
The scientists focused on whether dietary supplementation with a regular decaffeinated coffee prior to diabetes onset would improve insulin resistance and glucose control in laboratory mice that had diet-induced type 2 diabetes.
They gave the mice the supplement for a five-month period, assessing the genetic response in brain of the mice, revealing that the brain was able to more effectively metabolise glucose and then utilise it for cellular energy.
Study leader Giulio Maria Pasinetti commented “This is the first evidence showing the potential benefits of decaffeinated coffee preparations for both preventing and treating cognitive decline caused by type 2 diabetes, aging, and/or neurodegenerative disorders.”
Although coffee is not recommended for everybody, as it can lead to cardiovascular health risks, including high cholesterol and blood pressure, the study does show that some of the non-caffeine components in coffee offer health benefits for mice.
