Fiber plays a crucial role in promoting regular bowel movements by adding bulk to the stool and facilitating its passage through the digestive tract. A diet rich in fiber can help alleviate constipation and promote overall digestive health. There are two types of fiber: soluble and insoluble. Soluble fiber absorbs water and forms a gel-like consistency, while insoluble fiber adds bulk to the stool and speeds up its passage through the intestines. Include oats, barley, legumes (beans, lentils), fruits (apples, oranges, berries), vegetables (carrots, broccoli, Brussels sprouts), whole grains (whole wheat, brown rice), nuts, seeds, and the skins of fruits and vegetables in your diet. Increasing fiber intake gradually and ensuring an adequate intake of fluids can help prevent discomfort or bloating associated with sudden changes in fiber consumption.
