Since I eat a sweet potato almost every day, I usually wind up buying them about 5 pounds at a time. I get big ones, ones that are 350-500 grams (450 grams is a pound). I can eat one of these biggies, along with 4 tbsp of non fat sour cream, and I wind up getting most of my days potassium (especially if I sprinkle "No Salt") along with a good deal of fiber and magnesium.
I never really ate them much before except at Thanksgiving. Now I eat them a lot and have given up eating white potatoes pretty much.
Think of food as fuel for the body instead of feeding emotions
