The potato correction

In March 2008, I noted a comment in a book review in The Guardian that a person could live indefinitely on potatoes alone.

According to this article, about a man who is going to eat only potatoes for 2 months, that's not quite right:

Much research has been conducted on potatoes, and the conclusion drawn by every medical doctor and nutritionist on the planet is that you have to be nuts to think you can live off of potatoes.

To Voigt's credit, his lighthearted stunt will educate the public about many healthy aspects of the potato: a decent and inexpensive source of vitamin C, vitamin B₆, potassium, magnesium and, with the skin left on, dietary fiber.

Also, low-carb advocates are harsher on the potato than science allows them to be. Some potato varieties, prepared correctly, can be as healthy as the much-lauded whole grains. [7 Diet Tricks That Work]

Voigt didn't enter this diet blindly. He told LiveScience he first consulted with a doctor and dietician to confirm he could go 60 days on just potatoes. You need healthy kidneys to process the excess potassium delivered by 20 potatoes a day. You also need a store of nutrients potatoes lack, such as vitamin A for proper vision, or else exit this diet blindly.

(If you're wondering why a man would eat potatoes only for 2 months, it's because he's executive director of the Washington State Potato Commission. I guess this part of the job wasn't mentioned in his salary package.)

Seeing this blog has an inordinate amount of international influence (ha), I just thought I should note this.
