If you drink a cup or two of coffee every day, you may be cutting your chance of developing Alzheimer’s disease by about 20%.
Both caffeine and polyphenols, substances found in high quantities in coffee, have a protective impact on the brain, according to a new report presented at the Alzheimer Europe Annual Congress.
Polyphenols fight inflammation and the deterioration of brain cells, and caffeine prevents amyloid plaques and neurofibrillary tangles—both of which are strongly connected to the development of Alzheimer’s disease—from forming in the brain.
But to remain safe, stick to no more than three daily cups.
Other recent studies have discovered that consuming four or more cups a day could lower bone density; increase indigestion, palpitations, tremors, headaches, and insomnia.
