Sweet potatoes are a close second behind cranberries as an iconic holiday food. While the plain white potato is a high carb time bomb, sweet potatoes are packed with nutrition. They are actually related to morning glory flowers rather than the true potato. Sweets have as much fiber as famous - for- fiber oatmeal and about 30%RDA of vitamin C. For only about 120 calories, 1 cup of sweet potatoes has 500% RDA for vitamin A. This is almost scary high since too much vitamin A can cause bone and nerve problems. But unless some fool invents the sweet potato diet, one or two sweets/week will not cause a problem.
The real dangers with these orange beauties are the extra ingredients that are commonly added. Top of that list is of course marshmallows. Made of sugar,egg whites and corn syrup, these fluffy white gobs are like a glucose drip. Brown sugar, maype syrup, butter and cream are also common ingredients in sweet potato recipes. To add sweet potatoes to a holiday feast without adding risks for aging, enhance their flavor with cinnamon or nutmeg, and sweeten with Agave or sugar-free mayple syrup.
