Dietary fiber - self-care; Constipation - fiber
Fiber is a substance found in plants. Dietary fiber, the kind you eat, is found in fruits, vegetables, and grains. Your body cannot digest fiber, so it passes through your intestines without being absorbed much. However, fiber still provides many health benefits.
Dietary fiber adds bulk to your diet. Because it makes you feel full faster and for longer, it can help you with weight loss efforts or to maintain a healthy weight. For people with diabetes, fiber can play an important role in achieving and maintaining glycemic (blood sugar) control.
High fiber diets can also help with both constipation and diarrhea. Fiber also may help lower your cholesterol.
Slowly increase the amount of fiber in your diet. If you have bloating or gas, you have probably eaten too much and need to reduce the amount of fiber you eat for a few days. Drink plenty of fluids. When you increase fiber in your diet, you also need to get enough fluids. Not getting enough fluids may make constipation worse instead of better. Ask your health care provider or dietitian how much fluid you should be getting each day.
The daily recommended intake (DRI) of fiber for adults 19 to 50 years old is 38 grams a day for men and 25 grams a day for women. To get more fiber into your diet, eat different types of foods, such as:
Read food labels carefully to see how much fiber they have. Fiber is found naturally in many nutritious foods. If your diet is balanced, you likely do not need a fiber supplement. Whole grain products have more fiber than refined grains. Choose foods that have higher amounts of fiber, such as whole-wheat bread versus white bread and brown rice versus white rice. Try to eat foods that are naturally high in fiber. Fiber supplements and foods artificially fortified with fiber often do not deliver the same health benefits and may worsen bloating and gas.
