As far as veggies go, potatoes are one of the most popular, even with kids. They're tasty in pretty much any preparation (fried, baked, mashed), and they're one of the cheaper fiber sources in the produce aisle.
Of course, we're not talking fast-food fries here. We're talking about potatoes prepared in a healthy method, like frying in a small amount of olive oil, baking whole or mashing with some low-fat milk.
One medium-sized white potato provides about 2.9 grams of dietary fiber, and one medium sweet potato has almost 4 grams. Either way, you're getting about 10 to 15 percent of the average recommended daily fiber intake for a few dimes or less.
Another potato benefit? Extra nutritional bang for those dimes: Potatoes also offer a nice supply of potassium, another essential nutrient you may not be getting enough of.
