Coffee - a natural ally of brain health

Coffee is one of the favorite drinks of the Germans. It awakens energies, motivates and stimulates. What was previously unknown: Coffee protects our brain from dementia diseases like Alzheimer's and Parkinson's. A Canadian research team reports in a recent study that the stronger the degree of roasting of the beans, the more effective the protective function.

Contrary to earlier assumptions, more and more health benefits of drinking coffee are coming to light. Researchers at the Canadian Krembil Research Institute in Toronto recently found that coffee consumption lowers the likelihood of developing dementias such as Alzheimer's or Parkinson's. Compounds that appear during the roasting process of the coffee beans appear to be responsible for the protective effect. The study results were recently published in the specialist journal "Frontiers in Neuroscience".

Coffee - better than its reputation

Is coffee healthy or harmful to health? Numerous studies have dealt with this question in recent years. In the past, coffee was considered to be unhealthy because it was said to have a dehydrating effect that has since been refuted. In fact, coffee is healthier than most people think. It has a calming and stimulating effect and is intended to prevent type II diabetes and heart diseases. The latest research also suggests that coffee can protect our brain from neurodegenerative diseases. However, high coffee consumption can also contribute to acidification and thus promote stomach problems and reflux.

Roasting brings the protective effect

A Canadian team of scientists has proven that drinking certain types of coffee can be beneficial to brain health. But how does the popular hot drink support cognitive function? The researchers found the basis of the protective mechanisms not in caffeine, but in compounds that are released when the coffee beans are roasted.

The same effect for decaffeinated coffee

A heavily roasted caffeine-containing coffee was examined, as well as a heavily roasted decaffeinated and a mildly roasted caffeine-containing coffee. The team found that the strongly roasted varieties, regardless of caffeine, have a greater protective effect. In further tests, a number of compounds, the so-called phenylindanes, emerged as responsible for the positive effect. These compounds form during the roasting process and give the coffee its typical bitter taste.

How do the roasted compounds protect our brains?

According to the researchers, the roasted compounds in coffee ensure that less toxic proteins can combine in the brain. These so-called tau and beta-amyloid proteins are deposited as plaque in the brain and are thought to trigger neurodegenerative diseases such as Alzheimer's and Parkinson's.

The long roasting process is crucial

As the research team emphasizes, a long roasting time is responsible for the formation of the protective roasting compounds. It doesn't matter whether the coffee has been decaffeinated or not. The strongest protective effect on the brain comes from the dark-roasted varieties.

Mother Nature is the best chemist

The Canadian team is enthusiastic about the discovery, especially since the protective effect is based on a completely natural process. This does not require synthesis in the laboratory and makes the active ingredient easy to manufacture and widely accessible. "Mother Nature is a much better chemist than we are," explains Dr. Ross Mancini, a leading scientist in the study, released a press release on the study results.

Is coffee a cure for dementia now?

"This study was designed to show that there are indeed components in coffee that are useful in warding off cognitive decline," concludes Mancini. These processes are very interesting, but it is too early to declare coffee a medicine, the expert warns. (vb)

    I'm sorry, but, in my opinion, they were wrong. I am able to prove it. Write to me in PM, discuss it.
