Researchers from the University of Cincinnati (UC) have found that eating or drinking sweets may decrease the production of the stress-related hormone glucocorticoid--which has been linked to obesity and decreased immune response.
"Glucocorticoids are produced when psychological or physical stressors activate a part of the brain called the 'stress axis,'" said Yvonne Ulrich-Lai, PhD, a postdoctoral fellow in the department of psychiatry. "These hormones help an individual survive and recover from stress, but have been linked to increased abdominal obesity and decreased immune function when produced in large amounts.
"Finding another way to affect the body's response to stress and limit glucocorticoid production could alleviate some of these dangerous health effects."
The laboratory findings were presented during a poster session at the annual Society for Neuroscience meeting in Washington, D.C.
Dr. Ulrich-Lai and a team of researchers from the department of psychiatry showed that when laboratory rats chose to eat or drink sweet snacks their bodies produced lower levels of glucocorticoid.
She said that sweets--especially those made from sugar, not artificial sweetener--might do the trick.
"The sweets we are talking about are not the low-calorie, sugar-substitute variety," said Dr. Ulrich-Lai. "We actually found that sugar snacks, not artificially sweetened snacks, are better 'self-medications' for the two most common types of stress--psychological and physical."
Psychological stress could involve things such as public speaking, being threatened, or coping with the death of a loved one. Examples of physical stress are injury, illness, or prolonged exposure to cold.
