Dear Doctor: I have some dark chocolate every day and my (otherwise kind and loving) husband teases me for believing the news stories that chocolate is good for you. Please tell me that I haven't fallen for a bunch of quack science!

Dear Reader: We can certainly understand how the idea that chocolate offers health benefits might spark a bit of skepticism. After all, when we hear about so-called superfoods, it's foods like kale, fish oil or green tea that tend to top the list. The idea that something as delicious as chocolate might be anything more than an indulgence takes a bit of getting used to. And yet you're right -- a number of studies have linked chocolate with a range of positive outcomes. The results of recent research suggest that chocolate improves memory and brain function, lowers blood pressure and cholesterol, can boost immunity and has a positive effect on mood.
