In addition to strengthening our morning and day-to-day preservation, coffee has proven to have many benefits for health: one is intended to increase caffeine content and memory in the short term, but studies suggest that coffee has long-term protective effects on the brain.
Drink coffee was previously associated with a reduced risk of Alzheimer's and Parkinson's disease, but now scientists say they may have an idea why. It turned out that phenylindane-chemical compounds formed during the brewing process inhibit the growth of proteins associated with degenerative brain diseases. And darker, when the roast says, several of these protective compounds are in each cup.
For a new study, published in Limits in neurology, researchers at the Kremlin Brain Institute in Toronto analyzed the chemical components of three different samples of Starbucks Via Instant Coffee: a light roast, dark roast and caffeine with no odor. Then, the extracts of each sample were exposed to two types of proteins – amyloid beta and tau – which are known to have the characteristics of Alzheimer's and Parkinson's disease. Studies have shown that these diseases are more commonly found in the brain-forming clumps (known as amyloidal plates and protein tangi tau).

All three coffee extracts prevented the "scraping" of these proteins, suggesting that something in the American favorite morning preparation can be protected against the progression of the disease. And because the researchers did not notice any differences in the efficiency of regular decaffeated groves, they found that it was likely no caffeine that provides these benefits.
However, more inhibitory effects of two dark stoves were observed compared to light baking. For this reason, researchers thought about phenylindanes – compounds formed due to the decomposition of acids during roasting coffee, which are largely responsible for the bitter taste of coffee.
Phenylindanes are found in higher concentrations in coffee with longer baking times, such as dark baked and espresso. They have been shown to exhibit "surprisingly strong antioxidant activity", the authors wrote in their article, but their ability to interact with amyloid and tau proteins have not yet been reported.
In subsequent laboratory studies, it has been found that the phenylindane mixture actually prevents coughing with protein associated with the disease; in fact it was only studied the compound that influenced the amyloid and tau proteins. For tau protein it showed stronger inhibitions than any other investigated compound.

Given that both extracts of coffee from the dark cliff showed stronger protein inhibition compared to light baking, the authors suggested that it was a phenylindane coffee component, which in this sense was "largely responsible." (And good news for drinkers who drink children: Because the deco-fusion process happens before the authors assume that they do not affect phenylindane levels.)
This does not necessarily mean that everyone should start drinking espresso or drinking their coffee extras. The research is still preliminary, according to leading author Donald Weaver, MD, co-director of the Krembil Brain Institute, and it is still not widely known how these compounds actually work in the human body. (Plus, other studies have shown that they have lighter roasts higher different useful compounds, so they can still be rotated for general health.)

Weaver said in a press release that he hopes that this study will lead to a further study of phenylindanes and possibly also the development of medicines that could be used to treat neurodegenerative diseases. He also said that it is good to know that coffee has this natural asset for you, although there is insufficient evidence to drink exclusively for these reasons.
"What this study does is to take epidemiological evidence and try to improve and prove that there are actually components in the cavity that are useful to prevent a cognitive decline," Weaver said. "It's interesting, but we suggest coffee is a cure? Absolutely not."
Experts say that the best way to cope with the brain is to follow healthy eating, regular exercise and a lot of sleep. And if it turns out that Joe's daily cup matches with this plan, we are definitely all for it.
