Increased fecal bulk due to undigested carbohydrates and subsequent increased water loss, colonic gas and added weight has been shown to affect performance and slow racing speed in athletes.
Increased fecal bulk due to increased starch intake has been reported (Shetty and Kurpad, 1986).
Compared to the low fiber control, the wheat bran supplement
increased fecal bulk by 96 Â ± 14 g / d (p < 0.001) and the mean for both resistant starches was 22 Â ± 8 g / d greater than controls (p = 0.013).
Compared to the low fiber control, the wheat bran supple - ment
increased fecal bulk by 96 Â ± 14 g / d (p < 0.001) and the mean for both resistant starches was 22 Â ± 8 g / d greater (p = 0.013).
Fermentable dietary fibers
increase fecal bulking, increases bacterial mass, and dispose of the nitrogen that otherwise would be excreted through the kidneys.
Seaweeds may reduce the risk of poisoning from environmental pollution by providing fiber that
increases fecal bulk and also reduces cholesterol levels.
Thus, consumption of FOS may help to shorten fecal transit time,
increase fecal bulk and reduces constipation.
High doses of resistant starch (28 - 60 grams / day) have shown improved regularity (
increased fecal bulking with softer stools), and reduced secondary bile acids, ammonia and phenolics.
Cellulose was shown to
increase fecal bulk by 3 g / g of cellulose fed.
Although what consti - tutes â $ constipationâ $ is variously defined, diets that increase the number of bowel movements per day, improve the ease with which a stool is passed, or
increase fecal bulk are considered to be of benefit.
Generally speaking, all constipated cats will benefit from an increase in fecal water content but the main question is: Do we want to
increase fecal bulk (increase in diameter) with a soluble fiber?
Not exact matches
As a result of this rise in
fecal bulk material, the weight of stools
increase, and therefore the
fecal frequency also
increases.
In one study, participants were given 15 grams of inulin per day for two weeks and found that they had a significant
increase in stool frequency and
fecal bulk (2).
This is consistent with the small
increase in
fecal bulk seen with resistant starch intake in other studies (Behall and Howe, 1996; Cummings et al., 1996; Heijnen et al., 1998; Hylla et al., 1998; Phillips et al., 1995).
There also needs to be
increased validation of intermediate markers, such as polyp recurrence, and assess - ment of functional markers (e.g.,
fecal bulk) and its relationship to these endpoints.
As noted later in this chapter, an
increase in
fecal weight does not necessarily equate with enhanced laxation, so this needs to be considered in interpreting the results of
fecal bulking studies.
This meta - analysis concluded that pectin ingestion leads to an
increase of about 1.3 g of stool / g of pectin as compared to 5.4 g / g produced from wheat bran, suggesting that pectin is not an important
fecal bulking agent (Cummings, 1993).
