Yes, but if you HAVE to have sweet potato casserole, like my family does, a (much) lower calorie option is ideal. Everyone is always surprised when I say there's no brown sugar and that the meringue is just as good as sticky sweet marshmallows (I pick them off if someone else makes it with them). I'm perfectly happy eating my sweet potatoes with a 1/2 teaspoon of honey when I make them for my own dinner, or even plain if needed. I dont even think I've ever had sweet potato pie, not that I wouldn't try it, but it doesn't scream healthy. Portions are everything!
(Says the pregnant woman who had two large servings of mashed potatoes and noodles on Thanksgiving... lol)
