Eating potatoes with the skin as opposed to without the skin can increase dietary fiber intake. A medium-size baked potato weighs 173 grams. In Track Diet, compare Potatoes, White, Flesh and Skin (173 grams) with Potatoes, Baked, Flesh Only (173 grams).
A) How many more grams of fiber are in the potato with skin than the potato with flesh only?

Explanation:

In the internet, you can find that a regular potato (medium-sized) with the skin contains about 4 grams of fiber; and half that is  in the skin , thus a potato without skin contains about 2 grams of fiber.

In other site, I found that the source used to deal with this question states 4.2 grams of fiber for White, Flesh and Skin (173 grams) and 2.6 grams for Potatoes, Baked, Flesh Only (173 grams).

Therefore, using the second reference, the differnce in the amount of fiber, in grams,  for the potato with skin and the potato with flesh only is:

The answer is that there are 1.6g more of fiber in the the potato with skin than the potato with flesh only.
