Researchers find link between food odors and lifespan in fruit flies

s going slower in the animal, so you haven't fundamentally altered the way it has aged. So we wanted to make sure the effect of caloric restriction wasn't just slowing the animals down, and we found that it wasn't. You can have a high metabolic rate and be long-lived, and that's an encouraging observation."

Ultimately, understanding any link between human longevity and caloric intake, and the role our sense of smell may play in the process, will require more knowledge of the fundamental mechanisms at work, Van Voorhies said.

"You continue to work on the model organisms to try to figure out what the actual mechanism is, and then you can try to apply it to people," he said. "The pharmaceutical companies would like to be able to mimic the beneficial effects of caloric restriction by having you take a pill. But for that to work, you need to understand the mechanism by which caloric restriction extends longevity."

Sometimes ?as in the new discovery of a link between food odors and lifespan in fruit flies ?the questions get more complicated as scientists gain more knowledge.
