High-fiber foods

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.

Function

 

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.

High fiber diets can also help with constipation.

 

What to Expect at Home

 

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 a 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:

  • Fruits
  • Vegetables
  • Whole grains

Read food labels carefully to see how much fiber they have. Fiber is found naturally in nutritious foods. If your diet is balanced, you likely do not need a fiber supplement. Whole wheat products have more fiber than refined grains. Choose foods that have higher amounts of fiber, such as whole-wheat bread versus white bread. Try to eat foods that are naturally high in fiber. Foods that have added fiber and fiber supplements do not always have some of the benefits of fiber, such as making you feel full.

 

Vegetables, Legumes, and Nuts

 

Vegetables are a good source of fiber. Eat more:

  • Lettuce, Swiss chard, raw carrots, and spinach
  • Tender cooked vegetables, such as asparagus, beets, mushrooms, turnips, and pumpkin
  • Baked potatoes and sweet potatoes with skin
  • Broccoli, artichokes, squashes, and string beans

You can also get more fiber by eating:

  • Legumes, such as lentils, black beans, split peas, kidney beans, lima beans, and chickpeas
  • Nuts and seeds, such as sunflower seeds, almonds, pistachios, and pecans

 

Fruits

 

Fruits are another good source of fiber. Eat more:

  • Apples and bananas
  • Peaches and pears
  • Tangerines, prunes, and berries
  • Figs and other dried fruits

 

Grains

 

Grains are another important source of dietary fiber. Eat more:

  • Hot cereals, such as oatmeal and farina
  • Whole-grain breads
  • Brown rice
  • Popcorn
  • High-fiber cereals, such as bran, shredded wheat, and puffed wheat
  • Whole-wheat pastas
  • Bran muffins
