Orange foods (like sweet potatoes, carrots, squash, pumpkin, orange peppers) are rich in betacarotene. Plus, they taste soooo good. They are pretty sweet, when I roast a sweet potato in the oven (400 degrees, 1+ hours) the sugar in the skin caramelizes - delicious!

CSPI ranked the sweet potato number one in nutrition of all vegetables. With a score of 184, the sweet potato outscored the next highest vegetable by more than 100 points. Points were given for content of dietary fiber, naturally occurring sugars and complex carbohydrates, protein, vitamins A and C, iron and calcium. Points were deducted for fat content (especially saturated fat), sodium, cholesterol, added refined sugars and caffeine. The higher the score, the more nutritious the food. The reasons the sweet potato took first place? Dietary fiber, naturally occurring sugars, complex carbohydrates, protein, vitamins A and C, iron and calcium.
The numbers for the nutritional sweet potato speak for themselves: almost twice the recommended daily allowance of vitamin A, 42 percent of the recommendation for vitamin C, four times the RDA for beta carotene, and, when eaten with the skin, sweet potatoes have more fiber than oatmeal. All these benefits with only about 130 to 160 calories!
I don't have an issue with white potatoes, but I prefer sweet potatoes, they taste better to me and offer more health benefits. As a rule, I try to concentrate on eating the brightest, most colorful foods if I have a choice. Red grapes over green grapes, dark green romaine over iceberg, sweet potatoes over white potatoes, etc etc.
