Coffee – a natural allied brain health
Coffee is one of Germany's favorite drinks. It raises energies, motivates and stimulates. What Was Unknown: Coffee protects our brains against dementia like Alzheimer's and Parkinson's. The stronger the degree of prayer, the more effective the protection function, reports a Canadian research group in a new study.
Contrary to earlier assumptions, there are increasing health benefits for drinking coffee. Researchers at the Canadian Cancer Research Institute in Toronto recently found that coffee consumption reduces the likelihood of developing dementia such as Alzheimer's or Parkinson's. For the protective effect, especially compounds appear to be responsible, which occur during the roasting process of the coffee bean. The results of the study were published recently in the journal "Frontiers in Neuroscience".
Coffee better than its reputation
Is coffee fresh or harmful? Many studies have come up against this issue in recent years. Previously, coffee was considered to be quite unhealthy, as it is said to have a dehydration effect which is now considered to be the opposite. In fact, coffee is healthier than most people think. It calms and stimulates at the same time and will prevent type II diabetes and heart disease. The latest research also suggests that coffee can protect our brain from neurodegenerative diseases. High coffee consumption can also contribute to hyperacidity and thus promote gastric problems and reflux.
Roasting gives the protective effect
A Canadian science team has shown that drinking some coffee may be beneficial to the health of the brain. But how does the popular hot drink support the cognitive function? The researchers found the basis of the protective mechanisms not in caffeine, but in compounds that were released while roasting the coffee beans.
Same effect for caffeine-free coffee
A strong roasted caffeine-free coffee, as well as a strong caffeine-free decaffeinated coffee was examined. The team found that the heavily roasted varieties, regardless of caffeine, have a stronger protective effect. In further tests, a number of compounds crystallized, the so-called phenylindans, responsible for the positive effect. These compounds are formed during the roasting process and give the coffee its typical bitter taste.
How do the stews protect our brains?
According to researchers, the roasted compounds in coffee ensure that less toxic proteins can bind to the brain. These so-called tau and beta amyloid proteins are deposited as plaque in the brain and considered to be neurodegenerative diseases such as Alzheimer's and Parkinson's.
The long roasting process is crucial
As the research group emphasizes, it is especially a long rusting time that is responsible for the formation of protective rust compounds. It does not matter if the coffee is caffeine free or not. The strongest protective effect on the brain is therefore based on the dark roasted varieties.
Mother Nature is the best chemist
The Canadian team is excited about the discovery, especially since the protective effect comes from a completely natural process. This requires no synthesis in the laboratory 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 researchers in the study, in a press release on the study results.
Is coffee now a cure for dementia?
"The purpose of this study was to show that there are actually components in coffee that are useful for warding cognitive decline," concludes Mancini. These processes are very interesting, but it is still too early to declare coffee as a cure, warns the expert. (Vb)
