I don't usually serve sweet potatoes and potato salad in the same meal, but they were growing little shoots (both) so decided to use them but baked with some butter and pineapple. Right in the middle some how the stove top threw its circuit, and in the process, the oven was turned off, so they had a rough start and then over cooked. Sweet potatoes win the nutrition race and are only very distantly related to the potato which are part of the nightshade family. Also sweet potatoes are not yams, which really have little nutrition at all.
Here's a very nice chart from the Cleveland clinic.
