Vitamin C in a Baked Potato
Potatoes and Vitamin C

Baked potatoes are a good source of vitamin C.

Sanja Gjenero

One medium-sized baked (or roasted) potato with the skin has 17 mg vitamin C, so you'd need to eat about five baked potatoes (87 mg vitamin C) to get a day's worth of vitamin C.

Those five potatoes (served plain) would also have 649 calories and contain 10 mg niacin.

As much as I love baked potatoes (and I really love baked potatoes), I don't think I'd want to eat five of them just to get my vitamin C. Still, a potato a day isn't a bad idea:
