Candied sweet potatoes are a perfect example of an unhealthy Thanksgiving dish. Sweet potatoes on their own are good for you. They're full of vitamin A and beta-carotene, as well as some vitamin C. But when you mash them up, add butter, brown sugar and marshmallows, you might as well kiss any health benefits goodbye.
Plus, some people find them unappetizing, which we blame on the marshmallow layer. Melted, gooey, gluey marshmallows cover the dish like cement, and not in a good, s'mores-type of way. The converging layers of sweetness between marshmallow and sweet potato can be nauseating, especially after downing ample amounts of turkey and other, better sides (like anything that's not on this list).
