Dark chocolate may help with memory loss

Some good news for chocolate lovers. It has been proven to help your memory.

A new study suggests that a natural compound in cocoa, called flavanols, can reverse age-related memory loss.

Researchers say the compound increases connectivity and subsequently blood flow to a part of the brain critical to memory.

But as Doctor Richard Besser said on Good Morning America today, it's only dark chocolate and it takes a lot to have an effect.

"You would have to have the equivalent of 20 chocolate bars a day to take in as many flavanols as they had in this study. And it's not the milk chocolate that so many people like. That would hit your waistline, that would hit diabetes and other things," Besser said.

Flavanols are also found in tea and some vegetables.
