Researchers from the University of Copenhagen discovered that people who have an identified FGF21 - a hormone secreted by the liver - can affect a number of sweet intakes like candies, chocolates, cakes and ice cream. On that account, the liver has a great effect why there are people who have sweet tooth.

In a data found by Matthew Gillum, who led the research study along with Niel Grarup, an assistant professor at the University of Copenhagen, said that there is really surprising evidence of how the lifestyle of 6,500 Danish individuals affects their sweet tooth. Also at the same time, the researchers found that FGF21 a hormone secreted by the liver has a great role in regulating the food that an individual is eating, via Phys.org.  

Gillum and Grarup discovered that once food passed through the liver it put away sweets and the FGF21 a hormone secreted by the liver is also suppressing the sweet tooth in primates. However, to see how this hormone affects the human being, the researchers used Inter99 to gather data, which measures the glucose and level of cholesterol among the participants, Clinical Trial defined.

On that account, to have a better understanding of this FGF21 a hormone secreted by the liver and how it affects people with sweet tooth, researchers monitor the blood stream of a participant who took two cans of coke prior to testing. Gillum and Grarup measured the level of sweets among the participants within 12 hours and monitored the changes for 5 hours.

What Gillum and Grarup found is that the participant who doesn't like the sweets had an increased level of FGF21 a hormone secreted by the liver, up to 50% higher than those individuals with a sweet tooth. As of now, the researchers believed that this study can help them to discover variants associated with obesity and diabetes type 2.
