The study which was authored by Marilyn Cornelis of Public Health revealed that the amount of coffee one drinks and its effect on the person can be influenced by genes. The large scale genome-wide meta-analysis had 120,000 regular coffee drinkers of European and American ancestry and found out that there are six genetic variants linked to habitual coffee drinking.
The study was published online last October 7, 2014 in Molecular Psychiatry. Genetics have long been claimed to contribute to one's differences in response to coffee and caffeine. However, identifying the specific genetic variants has been quite a daunting task.
According to statistics, 54% of Americans who are 18 years old and above are coffee drinkers. Also, the statistics from coffee research shows that an avid coffee drinker drinks about 3.1 cups of coffee a day on an average. Worldwide,
Out of the eight genetic variants found, two were really known to possess characteristics similar to that of energy drinks. However, four were revealed to be related to how the person metabolizes coffee and how it stimulates the body of the person. They found a surprising discovery, that two genetic variants were related to cholesterol and blood sugar.
One nutrition researcher at the Fred Hutchinson Cancer Institute, mentioned that detecting the genes related to consumption may help physician in the future to identify patients that need to taper down drinking coffee.
Subsequently, Dr. Cornelis says that "Drinking coffee or caffeine can be linked to beneficial and serious health effects. The findings in this study will allow doctors to identify groups that will benefit from coffee consumption to achieve optimal health."
This can be a breakthrough in modern science and medicine. This will help a lot of people because diabetes and cholesterol levels can be controlled because high-risk individuals will be tested first before conducting the activity.
