 Sweet Tooth Secrets Revealed

Scientists have discovered that having a sweet tooth may reflect complex mechanisms which control the energy uptake of the body. Researchers have found that several sugar sensors present in the gut and pancreas are also present in the tongue's taste buds. This finding could help prevent overeating.

Researchers have discovered 2 detectors in the tongue which help the body spot sweet food. One such sensor known as the KATP channel monitors blood sugar levels (BSL) and when the BSL increases it triggers the release of insulin. These KATP channels which are present in the tongue help to adjust the sensitivity according to the metabolic needs. This sugar sensitivity could be lowered after eating something sweet or heightened if the metabolism needs more sugar.

Researcher Dr. Karen Yee said, "This knowledge may someday help us understand how to limit over-consumption of sweet foods."

The study was conducted on mouse cells and was reported in the journal Proceedings of the National Academy of Sciences (PNAS).
