Syracuse (WSYR-TV) - According to a new study, drinking two cups of hot chocolate a day may keep older people's brains sharper.
Harvard researchers studied 60 older adults, about a third of whom had poor blood flow to the brain.
When the subjects drank two cups of hot cocoa a day for a month, not only did the chocolate improve blood flow, it also led to faster thinking and a nearly 30 percent improvement in memory.
The concept that better blood flow improves thinking is an intriguing one, but the researchers warned that those who want to boost their brains should not prescribe themselves a chocolate bar.
Most chocolate comes packed with sugar and fat, downsides that could outweigh any mental benefits.
