Fast Facts on Dietary Fiber and Your Health

Fast Facts on Dietary Fiber and Your Health

Dietary fibers are the non-starch forms of carbohydrate obtained from plants and the human body cannot digest them.

Research has found an adequate intake of dietary fiber helps to reduce the risk of a number of cancers like breast cancer and colorectal cancer.     

Dietary fibers are classified as soluble and insoluble but most fiber-rich foods contain both types in varying degrees. The two types function differently in the body.

Two Types of Dietary Fiber

Soluble Fiber absorbs water and becomes gel in the intestine. This gel helps to slow digestion and is helps to lower your blood cholesterol.  Food sources of Soluble Fiber:  oatmeal, barley, nuts, seeds, peas, beans, lentils, carrots, cucumbers, apples, oranges, pears, berries.

Insoluble Fiber adds bulk to stools and helps to promote regular bowels movements. Eating a high fiber diet helps your body to digest foods and eliminate them faster. Food sources of Insoluble Fiber: include whole bran, nuts, whole grain products, corn, carrots, grapes, berries, and apple or pear peels. 

Unlike protein, fats and carbohydrates which are the parts of food that your body digests and absorb, dietary fiber passes through your digestive system intact. Dietary fiber is not considered a nutrient since your body doesn’t digest or absorb fiber but is an essential part of a healthy diet.

Health Benefits of Dietary Fiber

  7. Longer Life
  8. More Regular Bowel Movements
  9. All-Natural Detox

 

Daily Dietary Fiber Goals Recommendations

  1. Eat 3 or more pieces of fruit each day.
  2. Eat 3 or more ½-cup servings of vegetables each day.  
  3. Eat beans 4 times a week in salad, chili, or side dishes.  

 

Note: Don’t like vegetables much you can create some really great Fruit-Veggie smoothies: fruit, yogurt or milk, with added spinach or kale, chia seeds, flaxseed and ice or use frozen fruits.  

How Many Grams of Dietary Fiber do You Need Each Day?

Age                 Men                      Women

19-30           34 grams               28 grams

31 – 49       31 grams                25 grams

Over 50       24 grams               22 grams

Dietary Fiber requirements for children and teens:

  • Children 1 to 3 years: 19 grams of fiber/day.
  • Children 4 to 8 years: 25 grams of fiber/day.
  • Boys 9 to 13 years: 31 grams of fiber/day.
  • Girls 9 to 13 years: 26 grams of fiber/day.
  • Boys 14 to 19 years: 38 grams of fiber/day.
  • Girls 14 to 19 years: 26 grams of fiber/day.

If you normally don’t eat much dietary fiber but have decided to increase your daily intake of dietary fiber, start slow. Eating too much fiber to quickly can cause bloating, cramping and gas until your gut get use to more dietary fiber. Drinking more fluids throughout the day will also help dietary fiber pass through the gut more effectively. Use the lists below to determine how much dietary fiber you are eating daily. You can also find the dietary fiber by looking at the Nutrition Facts label.
