Why do some people tend to drink black coffee? .. A medical explanation that solves the mystery
Some people tend to drink black coffee or dark chocolate, and according to an American researcher, this bitter taste may be linked to a genetic factor.
Marilyn Cornelis, a researcher and professor of preventive medicine at Northwestern University in Chicago, said that whoever inherited a preference for black coffee "is lucky" because this drink has health benefits.
The American Academy indicated that consuming moderate amounts of black coffee, between three and five cups a day, has shown the ability to reduce the risk of several diseases, including "Parkinson's", heart disorders, type 2 diabetes and several types of cancer.
The researcher cautioned that benefiting from the benefits of coffee is mainly related to not adding harmful substances such as sugar or milk and flavors that increase calories, according to "Sky News Arabia".
She added that a person who wants to drink coffee should choose a cup of black coffee, because it is better in terms of health, and its effect is very different from coffee accompanied by milk.
She explained that black coffee is naturally devoid of calories, while the number of calories in coffee with milk may reach hundreds.
In a previous study conducted by Cornelis and her scientific team, it appeared that the genetic factor may explain the desire of some to drink black coffee, while others say that they do not like it because its taste is bitter for them.
She noted that people who have inherited a love of black coffee genetically, metabolize caffeine faster, and then they need to drink more.
In a new study published in the journal Nature Scientific Robots, the researcher provided fuller details about coffee drinkers, distinguishing between black coffee lovers and those who prefer to drink coffee with milk, among other groups.
The results of the study showed that those who prefer black coffee do so due to a genetic factor linked to the rapid metabolism of caffeine.
