Eating Sugar is Healthy Among Some Greenlanders

“Adult Greenlanders with the genetic variation have lower BMI, weight, fat percentage, cholesterol levels and are generally significantly healthier. They have less belly fat and might find it easier to get a six pack. It is amazing and surprising that a genetic variation has such a profoundly beneficial effect,” says University of Copenhagen biology professor Anders Albrechtsen.

Along with colleagues from the University of Copenhagen, the University of Southern Denmark, and plenty of analysis establishments and public companies in Greenland, Professor Albrechtsen analyzed knowledge from 6,551 grownup Greenlanders and carried out experiments on mice.

The outcomes exhibit that carriers of the genetic variation have what is called sucrase-isomaltase deficiency, that means that they’ve a peculiar means of metabolizing sugar within the gut. Simply put, they don’t soak up unusual sugar within the bloodstream the way in which folks with out the genetic variation do. Instead, sugar heads immediately into their gut.

“Here, gut bacteria convert the sugar into a short-chain fatty acid called acetate, which in previous studies has been shown to reduce appetite, increase metabolism and boost the immune system. That is most likely the mechanism happening here,” explains Mette Ok. Andersen, an assistant professor on the Center for Metabolism Research on the University of Copenhagen and first writer of the examine.

Why genetic variation is widespread amongst Greenlanders

The purpose for this widespread genetic variation amongst Greenlanders is because of a weight loss program that has stood out from that of the remainder of the world for millennia.

“It is probably due to Greenlanders not having had very much sugar in their diet. For the most part, they have eaten meat and fat from fish, whales, seals and reindeer. A single crowberry may have crept in here and there, but their diet has had minimal sugar content,” says Anders Albrechtsen.

He provides that this has made the genetic variation frequent, as there has by no means been a necessity to soak up sugar quickly within the bloodstream.

Genetic variation is hard on youngsters

While the variation has clear well being advantages for grownup Greenlanders, it’s problematic for his or her youngsters.

“Younger carriers of the variation experience negative consequences due to their different type of sugar absorption. For them, consuming sugar causes diarrhea, abdominal pain and bloating. Our guess is that as they age, their gut bacteria gradually get used to sugar and learn how to convert it into energy,” explains Torben Hansen, a physician and professor on the University of Copenhagen’s Foundation Center for Basic Metabolic Research.

He and the analysis workforce hope that they’ll use the outcomes of their new examine to put the groundwork for creating new medicine which may one day be used to deal with heart problems and weight problems.

“We can see that the genetic variation provides a better balance of fat in the bloodstream, which results in lower weight and consequently, fewer cardiovascular diseases. If you can develop a drug that inhibits the sucrase-isomaltase gene, then in principle, we might all be able to have equally strong health profiles,” he concludes.
