As one of the most widely consumed beverages in the world, coffee would not have many side effects for the consumer. However, consuming too much of it could adversely affect brain health over time, according to a new study from the University of South Australia. The results of the study were published in the journal Nutritional Neuroscience. The researchers conducted their work on more than 17,700 participants, ages 37 to 73, to study the effects of coffee on the brain.
After the studies, the researchers found that subjects who consumed more than six cups of coffee a day had a 53% increased risk of dementia and lower total brain volume than those who consumed one to two cups a day. “This is the most thorough study of the relationships between coffee, brain volume measurements, risk of dementia, and risk of stroke. It is also the largest study that considers volumetric brain imaging data and a variety of confounding factors, ”said lead author Kitty Pham in a statement.
Reduce adult consumption
The Food and Drug Administration has therefore advised healthy adults to limit their daily coffee consumption to around four or five cups, or around 400 milligrams of caffeine. In the United States, the number of people with dementia aged 65 and over is estimated to be 5 million in 2014. The Centers for Disease Control and Prevention estimates that it should be 14 million by 2060. It should also be noted that studies have shown that drinking three to five cups of coffee a day can help protect against Alzheimer’s disease.
