It comes as a bit of a surprise to the researchers, who last year discovered that precisely this genetic variation could be one of the reasons why some people have a particular craving for sweet things. People with this variation eat more sugar than others.
‘It sort of contradicts common intuition that people who eat more sugar should have less body fat. But it is important to remember that we are only studying this specific genetic variation and trying to find connections to the rest of the body. This is just a small piece of the puzzle describing the connection between diet and sugar intake and the risk of obesity and diabetes’, says one of the researchers behind the study, Associate Professor Niels Grarup from the Novo Nordisk Foundation Center for Basic Metabolic Research.
