Scientists Find The Key To Stop Sugar Craving: A Protein Molecule

Scientists have suggested that humans have, over time, developed a certain fueled desire for sugar-rich foods since glucose is the main energy source feeding our brain cells. A new study has generated results that might have shed light on our inner desire for sugar, by indicating that an enzyme known as glucokinase triggers our cravings.

Scientists might have discovered an answer to turning off the sweet tooth button of the brain. A protein molecule has been found to trigger sugar cravings. It is, in fact, an enzyme called glucokinase that is also present in the liver and pancreas.

The new study suggesting that glucokinase affects one’s desire for sugar involved tests on rats. The rats were made to have boosted protein activity in their brains. This caused them to preferentially consume more glucose. However, when glucokinase activity was reduced, the rats ate less glucose.

Glucose is the main energy source needed by our brain cells. The scientists explained that we are tuned to seeking foods rich in glucose. According to them, humans are wired to prefer glucose-rich foods. The researchers stated that their study results indicate that glucokinase has a central role to play to trigger our craving for sugar.

One of the authors stated that:

This is the first time anyone has discovered a system in the brain that responds to a specific nutrient, rather than energy intake in general.”

According to the researchers, a drug could be made to target glucokinase or some element in the chemical pathway that could prevent obesity.
