Many people consume sweets in response to stress. Now researchers may have discovered why. Sugar reduces levels of cortisol, the stress hormone.
The post-diet M.R.I. showed increased activity in the areas of the brain controlling fear and stress in the sugar group. The aspartame group showed decreased activity in those areas.
The senior author, Kevin D. Laugero, a nutritionist with the federal Department of Agriculture, said no one should conclude that sugar should be used as a stress reducer. But, he said, “the finding is intriguing because it suggests that there is a metabolic pathway sensitive to sugar outside the brain that may expose new targets for treating neurobehavioral and stress-related conditions.”
