When it comes to your digestive system, fiber is highly important. It has health benefits like lowering cholesterol, preventing constipation and even helping with weight loss. With the right amount of fiber, your body can digest food properly and regulate blood sugar levels. As important as it is, most people aren’t getting enough fiber from their diet. Although adding fiber-rich foods like lentils and chia seeds can help bring some soluble and insoluble fibers into your system, you can also take fiber supplements to increase your dietary fiber intake and keep your digestion on track.
