Standard high-fiber food charts hospitals recommend include fruit, grain, legumes and vegetable charts, states Mayo Clinic. The charts list information concerning serving size and fiber in grams. Topping the high-fiber fruit chart are raspberries, while whole-wheat spaghetti, split peas and artichokes lead the grain, legumes and vegetable lists.
Fiber and sufficient hydration help the digestion system work efficiently, notes Mayo Clinic. In addition, a high-fiber diet may lower the risk of certain conditions, such as obesity, heart disease and diabetes. Dietary recommendations suggest men aim for 30 to 38 grams of fiber a day, while women should receive 21 to 25 grams.
