(BOSTON) — A research team from the University of Georgia in the U.S. enlisted 51 students to perform two tasks of self control.

The first involved students meticulously crossing out the letter E on a page from a statistics book. Then subjects endured another tedious task: they were asked to identify the color of various words that flashed on a screen, with the words spelling out the names of other colors.

Half of the students rinse their mouths with lemonade sweetened with sugar for three to five minutes while performing the tests, while the other half rinsed with lemonade made with the artificial sweetener Splenda.

Turned out, the students who gargled with sugar were “significantly faster” in their responses than the Splenda group.
