Drinking a lot of coffee could help reduce the risk of multiple sclerosis.
A new study of people in Sweden and the US found rates of MS were consistently higher among those who drank little or no coffee.
In fact, drinking six or more cups a day was linked to a 30-percent lower risk of the disease.
Experts say caffeine appears to suppress the chemicals in the body that cause inflammation.
Researchers say there may be some other chemical component in coffee that is responsible for the association.
