Asked in Calorie Count
What percentage of the calories of a very high fiber food can be deducted from its total calorie count since the fiber is not digested?
The calorie count on most foods includes 4 calories/gram of fiber, although the body does not really digest fiber well. Estimates vary, but you can assume that no more than 1-2 calories will be absorbed per gram of fiber. Therefore, look at the number of grams of fiber, and subtract 2 x (grams fiber) from the total calorie count. I am not sure how well soluble fiber is digested by the body, so for soluble fiber, you may want to be more conservative.
