Japanese sweet potato vs regular sweet potato with orange flesh?

Question

What's the nutritional difference between these?

Answer 1

According to an article on Livestrong.com, Japanese sweet potatoes and "American" sweet potatoes are similar, with Japanese sweet potatoes tasting sweeter. I found several articles that talk about the nutritional values and properties of both types of sweet potatoes. (Each of the articles from Livestrong.com also references the sources that they used to find the information, and the others are from the USDA [United States Department of Agriculture] and the University of California).
