For example, after 12 weeks, mice fed a diet high in either saturated fats, or trans fats, developed a respective 30 percent, and seven percent disturbance of the Blood-Brain Barrier (BBB), and widespread inflammation with the brain and brain vascular tissue.
Why is this relevant?
According to the National Institute of Ageing (NIH), in a person with Alzheimer’s, a faulty blood-brain barrier prevents glucose from reaching the brain and prevents the clearing away of toxic beta-amyloid and tau proteins.
“This results in inflammation, which adds to vascular problems in the brain,” explains the NIH.
According to Dr Lee, high levels of cholesterol in midlife has been shown to increase the long term risk of Alzheimer’s Disease.
