Chocolate lovers have a lot to be happy about lately. New research is emerging all the time about the potential health benefits of this sweet treat. The cacao plant (from which chocolate is made) is a rich source of antioxidants called flavanols. Antioxidants keep you healthy by fending off free radical damage that leads to — among other things — cancer. And flavanols have specific benefits for your heart: They can lower blood pressure, make blood platelets less sticky and improve blood flow — all of which helps prevent heart disease.

But a brand-new study took a look at chocolate in a new light. The researchers' aim was to investigate not the well-documented vasodilating effect of some flavanols (which dilate blood vessels and lower blood pressure), but the vasoconstricting effect that others can have. "The sympathomimetics are stimulants that acutely vasoconstrict blood vessels and activate the brain in unique ways," explains Larry Stevens, Ph.D., a professor of psychology at Northern Arizona University and author of the study. The researchers had subjects eat 60-percent-cacao chocolate and then tested brain activity using EEG images. What they found is that after eating the chocolate, subjects experienced an immediate stimulant effect, their brains were more alert and their blood pressure increased temporarily. This makes chocolate perfect for combating what Stevens calls "the afternoon cognitive slump."

Not any old candy bar will do the trick, however. Look for dark chocolate bars that contain at least 60 percent cacao.

Here are a few that fill the bill:
