As you might be aware, cutting down the amount of sugar you ingest every day can be greatly beneficial to your health. But as bad as sugar may be for your overall health, there are a few common misconceptions people have when it comes to it. Thankfully, BrainCraft’s Vanessa Hill is here to clear some up; even those she accidentally reported on previously.

Sometimes parents won’t allow their children to have sugar because it makes them “hyper.” Even some adults abstain from having a sugary drink or candy for fear that they’ll get all riled up. “None of these studies found significant differences between kids who had sugar and those who didn’t,” Hart says in the video. “Often it’s kids’ surroundings that influence them to be ‘hyper.’”

While it is correct to say that sugar can cause teeth to decay, it technically doesn’t directly have a hand in rotting your teeth. Instead, high levels of lactic acid help to dissolve the enamel of your tooth. This can be from any food product left on your teeth — meats, dairy, carbs, and sugar. “The more sugar you eat,” Hart says, “the more residue you have on your teeth,” which can lead people to believe that sugar is the reason teeth are rotting.

The tongue map has been in most anatomy health books for years, even though it was debunked back in the mid-1970s. Hart even says the tongue map was in her textbooks both during her time as a student and as a teacher. The tongue map shows that your tongue has different areas that taste different tastes, when in reality your tongue's taste buds are all over your mouth and can all taste the same tastes.
