About this calculator

Most adults eat half the recommended fiber (15-18 g/day vs. 25-38 target). High-fiber meals: lentils, beans, whole grains, vegetables, fruits. The FDA "good source" cutoff is 3g/serving; "excellent" is 5g+. Fiber improves satiety, blood sugar control, and gut health. Aim for 25-38g daily total — easier with one fiber-rich meal (lentil soup, oatmeal-fruit breakfast) than spreading thin.
