Fiber is a vital aspect of any diet, and while there are many staple ingredients that are surprising sources of the roughage, making a conscious effort to integrate more of it into your meals can prove to be fairly difficult. However, there is one type of pasta that is not only a great source of fiber, but is also generally considered one of the healthiest versions of the product that you can use: legume-based pastas. It is made with chickpeas, black beans, red lentils, green lentils, or yellow lentils rather than wheat. The reason these pastas are such a great source of fiber is that legume beans are naturally much more fiber-rich than grains. Plus, because legume-based dishes are generally lower in carbs and higher in protein than other variations, the gluten-free alternative could be a legitimate game changer for many people looking to improve their diet.
