Researchers have discovered that the reason we eat sugar while stressed is because sugar reduces cortisol, the stress hormone.
Out of 19 volunteers, eight consumed artificially sweetened beverages while the rest drank a beverage containing 25 percent sugar.
Following the 12-day experiment, scientists found that cortisol levels were lower in the sugar consumers and higher in the non-sugar group.
A post-diet M.R.I. scan revealed more activity in the areas of the brain controlling fear and stress in the group that drank the artificially sweetened beverage.
