The stronger, the better – the coffee protects our brain

Coffee – a natural ally of brain health

Coffee is one of Germany's favorite drinks. Awakens energies, stimulates and excites. What was previously unknown: Coffee protects our brain from dementia like Alzheimer's and Parkinson's. The stronger the degree of baking beans, the more effective the protective function is, a Canadian research team said in a recent study.

Unlike previous assumptions, more and more health benefits from coffee come to light. Researchers at the Krembil Research Institute in Canada in Toronto have recently found that coffee consumption reduces the likelihood of developing dementia such as Alzheimer's or Parkinson's disease. For the protective effect, especially the compounds appear to be responsible, which arise during the roasting of the coffee beans. The results of the study were recently published in Frontiers in Neuroscience.

Coffee better than his reputation

Is coffee healthy or harmful? Many studies have reached this issue in recent years. In the past, coffee was considered unhealthy because it is said to have a dehydration effect that is now considered unjustified. In fact, coffee is healthier than most people. It is both calming and stimulating and supposed to prevent type II diabetes and heart disease. The latest research also shows that coffee can protect our brain from neurodegenerative diseases. However, high coffee consumption can also contribute to over-reaction and thus promote stomach and reflux problems.

Baking brings the protective effect

A Canadian scientific team has shown that eating some coffees may be beneficial to brain health. But how does the popular hot drink support cognitive function? The researchers found the basis of protective mechanisms not in caffeine, but in compounds released when roasting coffee beans.

The same result for caffeine-free coffee

A caffeine-high-roasted caffeine, as well as a strong caffeine-free and caffeinated coffee, as well as a slightly roasted caffeine coffee, were examined. The team found that heavy baked varieties, independent of caffeine, have a stronger protective effect. In further tests, a number of compounds, the so-called phenylindans, crystallized as responsible for the positive result. These compounds are formed during the baking process and give the coffee a characteristic bitter taste.

How do roasts protect our minds?

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

The long cooking process is crucial

As the research team points out, a long baking time in particular is responsible for the formation of protective roasting compounds. It does not matter whether the coffee was decaffeinated or not. The strongest protective effect on the brain is therefore based on dark roasted varieties.

Mother Nature is the best chemist

The Canadian team is excited about the discovery, especially because the protective effect comes from a completely natural process. This does not require composition in the lab and makes the drug so easy to produce and widely available. "Mother Nature is a much better chemist than us," explains Dr. Ross Mancini, one of the leading scientists in the study, in a press release on the results of the study.

Coffee is now a cure for dementia?

"The purpose of this study was to show that in essence there are ingredients in coffee that are useful in avoiding cognitive decline," concludes Mancini. These procedures are very interesting, but it is still too early to declare coffee as a remedy, warns the expert. (Vb)
