Is black pepper the new secret weapon against fat? A recent paper in the Journal of Agricultural and Food Chemistry claims that the piperine, an ingredient in black pepper, has the power to stop the body from making new fat cells, and could be used to treat obesity.
Endurance athletes sometimes say they're "addicted" to exercise. In fact, scientists have shown that rhythmic, continuous exercise — aerobic exercise — can in fact produce narcoticlike chemicals in the body.
Now researchers suggest that those chemicals may have helped turn humans, as well as other animals, into long-distance runners.
The man behind the research is University of Arizona anthropologist David Raichlen, a runner himself. He does about 25 miles a week.
