Cellulose is a complex carbohydrate and a type of polysaccharide made up of glucose molecules linked together in a way that the human digestive enzymes cannot break down.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Is Cellulose?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Cellulose is found in the cell walls of plants and provides structural support. It is the most abundant organic polymer on Earth. When humans eat plant-based foods (like fruits, vegetables, whole grains, and legumes), they also consume cellulose as part of dietary fiber.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why Can\u2019t Humans Digest Cellulose?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Human digestive systems lack the enzyme <strong>cellulase<\/strong>, which is needed to break the \u03b2(1\u21924) glycosidic bonds in cellulose. As a result, cellulose passes through the digestive system largely undigested. However, this is actually beneficial because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>It adds bulk to stool<\/strong>, which helps prevent constipation.<\/li>\n\n\n\n<li><strong>It promotes healthy bowel movements<\/strong> by stimulating peristalsis (muscle contractions of the intestines).<\/li>\n\n\n\n<li><strong>It helps regulate blood sugar and cholesterol<\/strong> by slowing absorption of sugar and fat.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Why Not the Other Options?<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Glycogen<\/strong> is a storage form of glucose in animals and is easily broken down during digestion.<\/li>\n\n\n\n<li><strong>Glucose<\/strong> is a simple sugar that is absorbed directly into the bloodstream in the small intestine.<\/li>\n\n\n\n<li><strong>Maltose<\/strong> is a disaccharide (two glucose units) and is broken down into glucose by the enzyme maltase.<\/li>\n\n\n\n<li><strong>Starch<\/strong> is a digestible plant polysaccharide made of \u03b1(1\u21924) glucose linkages, broken down by enzymes like amylase.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In contrast, <strong>cellulose\u2019s unique structure makes it indigestible<\/strong>, classifying it as <em>insoluble fiber<\/em>. It does not provide calories but plays a crucial role in maintaining digestive health. That\u2019s why it is commonly referred to as <strong>roughage<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What passes through the digestive tract as fiber or roughage?
