Your love for coffee is not linked, as previously believed, to your chances of developing diabetes or obesity, according to new genetic research from Denmark.
The Danish scientists isolated “coffee genes,” a number of genes that affect our desire for coffee. (Who knew your Starbucks habit was genetic?). Their study included DNA information and coffee drinking habits from 93,000 Danes from the Copenhagen General Population Study.
Focusing on the genetic component helps clarify coffee’s connection to obesity and diabetes. "We are the first in the world to have investigated the relationship with genes associated with a lifelong high consumption of coffee,” said Ask Tybjaerg Nordestgaard, a medical student in the Department of Clinical Biochemistry at Herlev and Gentofte Hospital, said in a University of Copenhagen release. “These genes are completely independent of other lifestyle factors, and we can therefore conclude that drinking coffee in itself is not associated with lifestyle diseases."
Previously, high coffee intake was observationally associated with low risk of obesity, metabolic syndrome and type 2 diabetes along with high body mass index, waist circumference, weight, height, systolic/diastolic blood pressure, triglycerides and total cholesterol, and with low high-density lipoprotein cholesterol, according to the research, which was published in the International Journal of Epidemiology. Sciencedaily.com noted the research.
"We can now see that the coffee genes are surprisingly not associated with a risk of developing type 2 diabetes or obesity,” Borge Nordestgaard, clinical professor at the Faculty of Health and Medical Sciences, University of Copenhagen, and senior physician at the Department of Clinical Biochemistry at Herlev and Gentofte Hospital, said in the release. “This suggests that drinking coffee neither causes nor protects against these lifestyle diseases.”
Drinking coffee does, however, boost antioxidant quotient. A recent study found that just the used grounds of coffee beans have 500 times more antioxidant power than vitamin C.
