A new research ofUniversity of South Australia shows that too much coffee could drag us into dementia. Experts involved in the research, the largest of its kind, have indeed found that exaggerated coffee consumption is associated with smaller total brain volumes and an increased risk of decline cognitive.
The study was published in the scientific journal Nutritional Neuroscience.
Coffee and dementia: is there really a correlation?
The study, carried out by the scientists of the‘Australian Center for Precision Health of UniSA At SAHMRI together with a team of international researchers, he observed the effects of coffee on the brain of 17,702 volunteers at the British biobank, di aged between 37 and 73 years, highlighting that those who drank more than six cups of coffee a day run the risk of a 53% increase in dementia.
The lead researcher and Ph.D. UniSA, Kitty Pham, said the study shows important public health insights: “Coffee is among the most popular drinks in the world. However, with global consumption of over nine billion kilograms per year, it is essential to understand the potential implications for health “, explained the scholar.
“This is the largest survey on connections between coffee, brain volume measurements, dementia risks and stroke risks: it is also the largest study taking data from volumetric imaging of the brain and a wide range of confounding factors. Considering all possible permutations, we have constantly found out that increased coffee consumption was significantly associated with reduced brain volume: in essence, drinking more than six cups of coffee a day could put you at risk for brain diseases such as dementia and stroke“, specified the scientist.
Dementia is a degenerative condition of the brain that affects memory, thinking, behavior and the ability to perform daily activities. Approximately 50 million people are diagnosed with the syndrome worldwide. In Australia, dementia is the second leading cause of death, with around 250 people diagnosed every day.
Stroke is a condition in which the blood supply to the brain is cut off, resulting in a 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. The data suggests that 13.7 million people will have a stroke this year with 5.5 million dying as a result.
The teacher Elina Hyppönen, senior researcher and director of the Australian Center for Precision HealthUniSA, states that while the news could be a bitter cup for coffee lovers, it’s about finding a balance between what you drink and what is good for your health.
“This research provides vital information on excessive coffee consumption and brain health, but as with many things in life, moderation is key.“, Says prof. Hyppönen.
“Together with other genetic evidence and a randomized controlled trial, these data strongly suggest that high coffee consumption can adversely affect brain health. While the exact mechanisms aren’t known, one simple thing we can do is stay hydrated and remember to drink some. of water next to that cup of coffee ”.
“Typical daily coffee consumption is between one and two standard cups of coffee. Of course, while unit measurements may vary, a couple of cups of coffee a day is generally fine. However, if you are finding that your coffee consumption is going towards more than six cups a day, now is the time to rethink your next drink.“, Advises Hyppönen.
In addition to dementia and stroke, does excessive consumption of coffee lead to other imbalances?
In another study, which made use of over 300,000 participants at the British Biobank, researchers examined the connections between the habitual consumption of genetically instrumented coffee and a full range of diseases, finding that too much coffee can increase the risk of osteoarthritis, arthropathy (joint disease) and obesity.
In previous research conducted by Professor Hyppönen and his team, six cups of coffee a day were considered the upper limit for safe consumption. The expert genetic epidemiologist, la professor Elina Hyppönen ofUniSA, in this regard, he explained that understanding the risks associated with the habitual intake of coffee could have very large implications for the health of the population.
“Globally, we drink about three billion cups of coffee every day, so it makes sense to explore the pros and cons of this on our health.”, Professor Hyppönen said, “Typically, the effects of coffee consumption are studied using a observational approach, in which comparisons are made with non-coffee drinkers. But this can deliver results misleading “.
Dementia and stroke: a genetic approach to the study of coffee consumption
“In this study, a genetic approach, called analysis MR-PheWAS, to establish the true effects of coffee consumption with respect to 1117 conditions clinics: “ Our findings suggest that moderate coffee drinking is mostly safe. But it has also shown that regular coffee consumption increases the risks of three diseases: osteoarthritis, arthropathy and obesity, which can cause significant pain and suffering for people with these conditions. “
Professor Hyppönen states that the prevalence of these conditions in Australia and around the world shows how important it is to determine the possible causes and factors affecting diseases: “Excessive coffee consumption can lead to an increased risk of some diseases“Says Professor Hyppönen.
“For people with a family history of osteoarthritis or arthritis, or for those who are concerned about developing these conditions, these findings should serve as a warning message. The body generally sends powerful messages regarding coffee consumption, so it is imperative that people listen to them when they consume coffee ”.
“Although these results are in many ways reassuring in terms of dAndl general coffee consumption, the message we should always remember is consume coffee in moderation: this is the best solution to enjoy coffee and also in good health ”The scientist concluded
