Staying Away from Sweets may Increase Longevity
The October issue of Cell Metabolism, a publication of Cell Press has revealed that worms live longer when they are unable to process glucose. Glucose is the key source of energy for the body and is a major constituent of all starches and other forms of sugar like sucrose and lactose.

“In the US and Europe, added sugar accounts for 15 to 20 percent of daily calories, and the breakdown of that sugar always generates glucose,” said Michael Ristow of the University of Jena in Germany and the German Institute of Human Nutrition Potsdam-Rehbrücke. If the findings in worms hold for humans, it “suggests that, in healthy people, glucose may have negative effects on life span.” The findings may also cast some doubt on the prevailing treatments for type 2 diabetes, all of which are aimed at lowering blood levels of glucose by increasing the amount of sugar taken up by body tissues, Ristow said.

What’s more, Ristow’s group further demonstrated in their report that antioxidants and vitamins given to the worms erased the life-extending benefits of sugar deprivation, raising questions about the widespread use of antioxidant supplements, according to the researchers.

In westernized countries, glucose represents a key dietary component since the most commonly ingested sugar, sucrose, contains equal amounts of glucose and fructose, the researchers noted. Nevertheless, it is a matter of debate whether glucose and other carbohydrates have a relevant effect on disease burden and mortality in humans, they said.
