While drinking coffee is a popular morning ritual, new research shows that drinking too much coffee could be affecting brain health. Researchers recently found that excessive consumption of coffee reduces overall brain volume and increases the risk of dementia. For those with more than sixDrinking cups of coffee every day, this risk was 53 percent higher.
How high coffee consumption affects the brain
The international research team examined theEffects of coffee on the brainof 17,702 participants aged 37 to 73 years. Since global consumption is more than nine billion kilograms per year, the scientists wanted to look for possible health risks. To do this, they used volumetric imaging of the brain and took a variety of confounding factors into account. Essentially, the results showed that drinking more than six cups of coffee per day poses a risk of brain diseases such as dementia and stroke. A stroke is the condition in which the blood supply to the brain is disrupted. This can lead to oxygen deprivation, brain damage and loss of function. Worldwide, one in four adults over the age of 25 will suffer a stroke in their lifetime. The news may be bitter for coffee lovers, according to the study authors. However, it's about finding a balance between what people eat and what is good for their health.
This research provides insights into brain health, but as with many things in life, moderation is key. This, along with other genetic evidence and a randomized controlled trial, suggests that high coffee consumption is dangerous to health. The exact mechanisms are not yet known. Scientists simply recommend people stay hydrated and drink some water with every coffee. Daily coffee consumption should be between one and two standard cups of coffee. Of course, the units of measurement can vary, but according to the authors, a few cups of coffee a day would bethis studygenerally fine. However, when people approach more than six cups a day, it's time to reconsider their next drink.
