How to Measure the Fiber in Fruit

Dietary fiber is an important part of every person's daily diet. The United States Department of Agriculture recommends that adults consume at least 25 grams of fiber per day. Dietary fiber aids in digestion and also helps you feel full longer after eating. A diet that is high in fiber can also help lower your cholesterol, maintain bowel regularity and keep your blood glucose levels low. Most fruits are a good source of fiber.

Instructions

• 1

  Find the nutrition information for the fruit you want to eat. You can do this by visiting the United States Department of Agriculture National Nutrient Database where foods and their nutritional content are listed alphabetically.

• 2

  Determine the serving size of the fruit that you are eating. If you are eating fresh fruit, one whole fruit may be the serving size, but unusually large pieces of fruit may contain more than one serving. You should also carefully check the serving size if you are eating dried or canned fruit.

• 3

  Multiply the number of servings you are consuming by the grams of fiber determined from either Livestrong's MyPlate or the USDA website. For example, if you are eating one whole apple, the amount of fiber in the fruit is 3 grams. If you are eating two apples, there are 6 grams of fiber total.
