What Is Fiber?

Fiber is found in fruits, vegetables, grains, nuts, seeds, dried beans, split peas, and lentils. It is the part of plants that the body cannot digest easily. Fiber includes plant cell walls (cellulose) and other substances, such as pectin and gums. There is no dietary fiber in meat or dairy products.

We need to eat fiber for good health. A high-fiber diet may lower the risks for certain cancers, heart disease, and even obesity. Most Americans' diets contain, on the average, about 10 grams of fiber. Try to choose foods that add up to 20-30 grams of fiber per day. The chart on page 3 will help you figure how much fiber is in foods.

Remember that a diet too high in fiber (more than 35 grams per day) is not recommended. As is true of other nutrients, some fiber is needed--but too much can unbalance your diet.

Adding Fiber

The U.S. Food and Drug Administration (FDA) has defined a high-fiber food to equal 5 grams of fiber per serving. A good source of fiber equals 2.5 grams to 4.9 grams of fiber per serving.

There are many ways to add fiber to your diet:

  • Add sliced fresh fruit to cereal, yogurt, or cottage cheese.
  • Use whole grain breads (which contain at least 3 grams of fiber per serving) in place of white bread.
  • Choose whole-grain crackers.
  • Use fresh fruit and vegetables every day. Eat vegetables at almost every meal and snack on fresh or dried fruit, raw vegetables, or low-fat popcorn
  • Use more beans and peas in meals. Try split pea or lentil soup, brown rice and beans, or chili.
  • Choose high-fiber cereals (5 grams of fiber or more per serving) for breakfast in place of refined, sugary cereals.
  • Eat potatoes with the skin.
  • When you cook vegetables, steam or stir fry until they are tender but still crisp.
  • Use sunflower seeds, sesame seeds, or wheat germ for toppings on casseroles, or add them to baked goods like quick breads and cookies.
  • Look for recipes using whole wheat or white whole wheat flour. Whole wheat flour has 4 times the fiber of white flour.
  • In recipes, use brown rice instead of white. It has 5 times as much fiber. Whole wheat pasta has 3-4 times as much fiber as white pasta.

How Much Fiber Do Children Need?

Experts in children's nutrition agree it's important to teach children healthful eating habits when they are young. But what about fiber? We haven't heard much about its benefits for children.

We're beginning to understand fiber's importance in children's diets. It has key health benefits in promoting regularity. Fiber not only helps to maintain good health as children grow, it helps them establish eating patterns that may assist in reducing their risk of developing heart disease and some types of cancer later in life.

The Dietary Guidelines for Americans recommends that after children are two years old, the fat in their diets should be lowered gradually until it reaches the level recommended for adults, around age five. As we lower the fat, we need to provide more foods rich in fiber, vitamins, and minerals.

We do need to be careful how much fiber we give children. High-fiber diets can reduce the amount of calories children get because foods high in fiber tend to be bulky and low in calories. Fiber can also bind minerals so that they are not available for the child to absorb. But most children currently do not get enough fiber.

Dietary fiber should be increased gradually. Caution is especially prudent for groups that may not be getting enough calories or minerals, such as preschool children, adolescents with mineral-deficient diets, children with inadequate nutrition, and some vegetarian children who have nutritionally inadequate diets. The best way to add fiber is by increasing the amounts of fruits, vegetables, legumes, cereals, and other grain products consumed. It's also important for anyone who is eating more fiber to drink extra liquids, including water, juice, or milk.

So how much fiber should children eat? Until recently there were no formal guidelines geared for children's needs and their developmental cycle. Now we have a fiber recommendation for children ages 3-18. The new formula is the child's age plus 5. For example, a five-year-old child needs about 10 grams of fiber, 5 + 5 = 10. This formula allows for the greater need for fiber as the child grows.
