By the Numbers: Coffee

In honor of National Coffee Day on Sept. 29, we sit back with a steaming cup of joe and look at some coffee numbers. In addition to the caffeine jolt many coffee drinkers seek, studies have shown health benefits to coffee drinking that includes offering protection against Parkinson’s disease, type 2 diabetes and liver disease. A new study by German scientists was able to modify a common age-related heart defect in mice with doses of caffeine that amounted to about four cups of coffee for a human. The molecular action of caffeine apparently enhances heart cell function and protects cells from damage (still unknown whether that applies to humans). Coffee also appears to improve cognitive function and decreases the risk of depression. So, cheer up with a cup.
