If I've said it once, I've said it a thousand times: the jury is still out on whether or not caffeine is good for you. As a matter of fact, I should have actually put it this way: if I've said it once, I've said it 21,000 times -- because that's how many studies have been conducted on the effects of caffeine, yet the last word on the matter has yet to be spoken.

Until now. No, I'm just kidding. I have new information, but certainly nothing that can be considered the last word. In typical caffeine-related fashion, the new information I have is contradictory; one study shows its benefits, while the other its detriments.

Let's start first with the good news. A new study from Harvard found that women who consume at least 500mg of caffeine daily were 20 percent less likely to develop ovarian cancer than those who consumed far less. Now for the bad news. A Duke University study revealed that people with diabetes (type 1 and type 2) who consume 500mg of caffeine daily witnessed an average increase of eight percent in their blood glucose levels.

Like I said, it's new information. Does it get us any closer to a verdict? Not really. Just the same, I'd be interested to hear your thoughts on whether or not you think caffeine is good for you. Feel free to weigh in on the issue in the comments section.
