There are new mixed messages from the medical community about the health benefits of coffee and tea.

A new study is questioning existing research that shows drinking a cup of coffee or tea can help prevent dementia and stroke.

Researchers from Harvard and the Netherlands found no prevention benefits in people who drink coffee or tea.

This latest study, which contradicts previous studies, is published in the journal "Neurology."
