They are not digested by human metabolism and do not release monosaccharides. That is, they travel through the entire intestinal tract intact and the microflora is responsible for consuming them. What remains is eliminated through the normal mechanism of waste expulsion from the body.<\/p>\n<p>Fructooligosaccharides or FOS do not provide calories and do not cause weight gain, but they also do not serve for weight loss. However, they have properties and benefits that improve digestion and speed up the transit of other foods. They act as <strong>digestive fiber<\/strong>.<\/p><div class=\"clear\"><\/div><center><aside class=\"ads2\"><ins class=\"adsbygoogle\" style=\"display:block; text-align:center;\" data-ad-layout=\"in-article\" data-ad-format=\"fluid\" data-ad-client=\"ca-pub-9582652217436894\" data-ad-slot=\"1797353553\"><\/ins><script>(adsbygoogle = window.adsbygoogle || []).push({});<\/script><\/aside><\/center><div class=\"clear\"><\/div>\n<h2><span id=\"Uses-as-prebiotics\">Uses as prebiotics<\/span><\/h2>\n<p>In the colon, they are fermented by colonies of anaerobic bacteria that all human beings have.

They are considered <strong>natural prebiotics<\/strong>. Many times they can be found in processed foods as a base for probiotics.

There is a real drop in pH and the <a href=\"https:\/\/www.mismumi.com\/en\/types-of-calcium-and-benefits\/\">benefits of calcium-containing products<\/a> increase due to greater bioavailability. The mineral Ca is more soluble in an acidic environment.
