HHS HealthBeat (August 21, 2013)

The oversweetened heart

From the U.S. Department of Health and Human Services, I’m Ira Dreyfuss with HHS HealthBeat.

Being a sweetheart is a good thing for romance but apparently a bad thing for a real heart. Researcher Heinrich Taegtmeyer of the University of Texas Health Science Center at Houston saw this in data on heart cells.

Dr. Taegtmeyer says an overload of a product of sugar called G6P created an imbalance in protein in the heart:  

“The heart muscle cell is unable to cope with this protein load, and it starts to weaken – it contracts less strongly.”

He believes this can contribute to heart failure, so he advises people to watch their diets – notably sweets – and burn excess sugar by being physically active.

The study in the Journal of the American Heart Association was supported by the National Institutes of Health.
