It helps keep things moving smoothly (you know what we mean), it can lower our risk for diabetes and heart disease and it keeps us fuller, longer. What is this magic stuff? Dietary fiber! It's essential to our diets, plus a high-fiber nibble can buy us time before the next meal hits the kitchen table. Here are 31 of our favorite fiber-packed snacks -- one for every day of the month. We opted for snacks with at least five grams of fiber (20 percent of the daily recommended value) to tide you over. Instead of turning to chalky store-bought high-fiber bars, try out some of these tastier choices.
