Spoonful Of Sugar' Makes The Worms' Life Span Go Down

Science Daily, Nov. 5, 2009

By adding just a small amount of glucose to the C. elegans worm diet, University of California, San Francisco and Pohang University of Science and Technology researchers found the worms lose about 20 percent of their usual life span, suggesting that a diet with a low glycemic index may extend human life span.

They trace the effect to insulin signals, which can block aquaporin channels that transport glycerol.

Further studies are needed to see if these same effects of sugar can be seen in mice, or even people.
