Healthy Food #4: Potatoes

One red potato contains 66 micrograms of cell-building folate — about the same amount found in one cup of spinach or broccoli.

One sweet potato has almost eight times the amount of cancer-fighting and immune-boosting vitamin A you need daily.

Quick Tip:

Let your potato cool before eating. Research shows that doing so can help you burn close to 25 percent more fat after a meal, thanks to a fat-resistant starch.
