Drinking more than six cups of coffee per day increases the risk of dementia and brain diseases, such as stroke, by 53%. Moderating consumption is the way out
Research from the University of South Australia found that high coffee consumption is associated with lower total brain volumes and a higher risk of dementia. The study evaluated 17,702 participants and indicated that those who drank more than six cups of coffee daily had a 53% higher risk of dementia and also of brain diseases such as stroke.
Dementia is a degenerative brain disease that affects memory, thinking, behavior and the ability to perform daily tasks. In Australia, dementia is the second leading cause of death, with around 250 people diagnosed each day. A Cerebrovascular accident, more known as a stroke, is a condition in which the blood supply to the brain is interrupted, resulting in lack of oxygen, brain damage and loss of function. Globally, one in four adults over the age of 25 will have a stroke in their lifetime.
According to researcher Elina Hyppönen, the key is moderation. “The way is to find a balance between the volume consumed and what is healthy”. While unit measurements may vary, a daily pair of cups of coffee is usually a good volume. “However, if coffee consumption exceeds more than six cups a day, it’s time to rethink.”
