Coffee – a natural ally of brain health
Coffee is one of the favorite drinks of German people. It arouses energy, motivates and stimulates. What was previously unknown: Coffee protects our brain against dementia such as Alzheimer's and Parkinson's. The stronger the level of roasted peanuts, the more effective the protective function, report the Canadian research team in the latest study.
Contrary to the previous assumption, more and more health benefits from drinking coffee are revealed. Researchers at the Canadian Krembil Research Institute in Toronto recently found that coffee consumption reduces the chances of developing dementia such as Alzheimer's or Parkinson's. For protective effects, certain compounds appear to be responsible, which arise during the roasting process of coffee beans. The results of the study were recently published in the journal "Frontiers in Neuroscience".
Coffee is better than its reputation
Is coffee healthy or dangerous? A number of studies have emerged against this question in recent years. In the past, coffee was considered rather unhealthy because it was said to have a dehydration effect which is now considered rejected. In fact, coffee is healthier than most people believe. It is calming and stimulating at the same time and should prevent type II diabetes and heart disease. Recent research also shows that coffee can protect our brain from neurodegenerative diseases. However, high coffee consumption can also contribute to hyperacidity and thus promote stomach problems and reflux.
Roasting produces a protective effect
The Canadian science team has proven that drinking certain coffees can be beneficial for brain health. But how do popular hot drinks support cognitive function? The researchers found the basic protective mechanism was not in caffeine, but in the compounds released during roasting coffee beans.
The same effect for decaffeinated coffee
Baked caffeinated coffee, and strong decaffeinated coffee and slightly baked caffeinated coffee are examined. The team found that baked, decaffeinated varieties had a stronger protective effect. In further tests, a number of compounds, called phenylindanes, crystallize as being responsible for positive effects. These compounds are formed during the roasting process and give a bitter taste to coffee.
How do baked compounds protect our brain?
According to the researchers, baked compounds in coffee ensure that less toxic proteins can bind to the brain. This is called tau and beta-amyloid protein deposits as plaques in the brain and are thought to trigger neurodegenerative diseases such as Alzheimer's and Parkinson's.
The long roasting process is very important
As the research team emphasized, long roasting times are especially responsible for the formation of protective roasting compounds. It doesn't matter whether the coffee doesn't contain caffeine or not. The most powerful protective effect on the brain is therefore based on dark roasted varieties.
Mother Nature is the best chemist
The Canadian team was very interested in this discovery, mainly because the protective effect came from a completely natural process. This does not require laboratory synthesis and makes the drug so easy to produce and widely available. "Mother Nature is a chemist who is far better than us," explained Dr. Ross Mancini, one of the leading scientists in research, in a press release on the results of the study.
Is coffee now the cure for dementia?
"The purpose of this study is to show that there are actually components in coffee that are useful for counteracting cognitive decline," Mancini concluded. This process is very interesting, but it is still too early to declare coffee as a drug, warn experts. (Vb)
