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.
Healthy eating 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 in this healthy food.
