Can Coffee Protect Your Brain? Find the Answer here

Now, research after research has proven that drinking certain types of coffee can be beneficial for brain health. However, what makes this popular drink affect cognitive function? How is the mechanism?

A 2016 study from the University of Ulster in Coleraine, England, concluded that one of the benefits of coffee is that it can protect the brain from cognitive impairments and improve thinking skills. For the mechanism, a new study developed by the Krembil Brain Institute has the answer. The results have also been published in the journal Frontiers in Neuroscience in October 2018 ago.

Researchers from the Krembil Brain Institute found that the key is not the caffeine content in coffee, but the presence of compounds released in the process of roasting coffee beans. This compound is called phenylindane.

The role of the coffee roasting process

In the study, the researchers tried to see the effects of three types of coffee, namely caffeinated dark roast coffee, caffeinated light roast coffee, and decaffeinated dark roast coffee.

"In our first experimental test, caffeinated and decaffeinated dark roast coffee both had identical potential. So, from the beginning we observed that the effect of this protective effect was not caused by caffeine," said the study's author Dr. Ross Mancini, a researcher in the field of medical chemistry.

Therefore, the researchers no longer focused their attention on caffeine, but on a collection of compounds in coffee called phenylindane. This compound is formed during the process of roasting coffee beans and which makes the coffee taste bitter.

This phenylindane compound seems to be able to inhibit clumps of tau and beta-amyloid. The two compounds are toxic proteins. When they accumulate excessively in the brain, they can trigger neurodegenerative conditions such as Alzheimer's and Parkinson's.

It was also known in the study that longer baking times will make coffee beans produce more phenylindane. This shows that dark roast coffee - both caffeinated and decaffeinated - both have a strong protective effect on the brain.

This study is the first to examine phenylindhane interactions with proteins responsible for Alzheimer's and Parkinson's. In the future, the researchers hope to conduct a more detailed study of the properties of phenylindane, and their effects on the body after digestion.

"What this study is doing is taking epidemiological evidence and showing that there are indeed components in coffee that are useful for counteracting cognitive decline. This is interesting, but do we suggest that coffee can be used as a drug? Of course not," he warned.

Drinking coffee is delicious, both in the morning or at rest. What's more, the compounds in coffee actually play a role in protecting the brain. It's just that, all the research above still needs stabilization so that the efficacy of coffee for brain health becomes increasingly clear.


From the explanation above, it can be concluded that coffee has a protective effect on decreasing cognitive function. However, it should be noted how much your coffee consumption habits every day. Remember, even though coffee has a beneficial effect on you in terms of cognitive and work performance, but excessive coffee consumption can also increase your risk of experiencing various diseases, such as insomnia, muscle tremors, stomach disorders, faster heart rate, and so on. Either way, limit your consumption of coffee every day to no more than 3 cups of coffee per day.
