Another coffee study published last month is touting benefits of the beloved beverage.
Alzheimer's in seconds, studies find
According to new research published in the journal Frontiers in Neuroscience, Drugs can protect against Alzheimer's and Parkinson's disease.
Scientists with the Krembil Brain Institute in Canada may be affected by age-related cognitive decline.

They examined three types of coffee (light roast, dark roast and decaffeinated dark roast) and conducted experimental tests that showed the effects of a group of compounds known as phenylindanes, which form the process of roasting coffee beans and give coffee its bitter flavor.
According to the study, the compounds inhibited two protein fragments often found in Alzheimer's and Parkinson's patients from "clumping."
"So phenylindanes are a dual-inhibitor," Donald Weaver's lead researcher said in a statement. It's "very interesting, we were not expecting that."
Because roasting leads to higher quantities of phenylindanes, it seems to be more protective than light roasted coffee, according to Weaver and his colleagues.

"It's the first time anybody's investigated how phenylindans interact with the proteins that are responsible for Alzheimer's and Parkinson's," fellow researcher Ross Mancini added.
While it is unclear how beneficial these compounds are, it is useful to understand that cognitive decline, "said Weaver. . "It's interesting but we are suggesting that coffee is a cure? Absolutely not. "

Alzheimer's disease is the sixth leading cause of death in the United States. In fact, the death rate of the disease has risen by 55 percent in recent decades, according to the CDC. And in Georgia, the number of deaths from Alzheimer's has increased by 201 percent since 2000, according to Georgia Health News.
The Atlanta-based Centers for Disease Control and Prevention recently revealed that the country's burden of Alzheimer's disease is 2060.
In 2014, 5 million Americans – or 1.6 percent of the population – felt the burden of diseases. The figure is expected to grow to 13.9 million, equating to nearly 3.3 percent of the projected population in 2060.
According to the Parkinson's Association, an estimated seven to 10 million people in the world are living with the neurological disease.
