The truth is that most people today consume less than half the fiber they used to. <\/p>\n\n<p>This decline has serious consequences for our health and especially for our gut. A lack of these important fibers can not only lead to digestive problems, but also disrupt the balance of important bacteria in our intestines. <\/p>\n\n<p>In this article you will learn why fiber is crucial for your diet and health and how you can effectively integrate it into your everyday life to support your digestion and promote your gut health.<\/p>\n\n<div id=\"ez-toc-container\"

and why is it important?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>You may have heard of dietary fiber, but do you know what it actually is and why it is so important for your health? Dietary fiber is a component of food that cannot be broken down by the body&#8217;s enzymes. <\/p>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Definition_and_basics\"><\/span>Definition and basics<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>Dietary fibers are indigestible carbohydrates found in plant-based foods. They play an important role in digestion and help to keep the intestines healthy. A sufficient intake of dietary fiber is important for a healthy diet.  <\/p>\n\n<p>Eating fiber supports intestinal health and can help prevent various health problems. A high-fiber diet can also contribute to satiety and thus help with weight control. <\/p>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_historical_development_of_our_fiber_intake\"><\/span>The historical development of our fiber intake<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>In the past, diets were much richer in fiber than they are today. In our western latitudes, there used to be significantly more cereals on the menu in the form of porridge, soups and, above all, high-quality bread. These foods were rich in fiber.  <\/p>\n\n<p>Dietary fiber intake has changed dramatically: People used to consume about 80 grams of fiber per day, but today the average is only about 25 grams for men and about 23 grams for women. This development is closely linked to changes in our eating habits. <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Modern flour production removes the fiber-rich husk from the grain kernels.<\/li>\n\n\n\n<li>Wholemeal products were replaced by white flour products.<\/li>\n\n\n\n<li>Highly processed foods have replaced natural, fiber-rich foods.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Soluble_and_insoluble_fiber_the_difference\"><\/span>Soluble and insoluble fiber: the difference<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>When talking about fiber, you need to distinguish between two main types: soluble and insoluble fiber. Both play an important role in your diet and have different effects on your digestion. <\/p>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Properties_of_soluble_dietary_fiber\"><\/span>Properties of soluble dietary fiber<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>Soluble fiber dissolves in water and forms a kind of gel that affects your digestion. They are mainly found in foods such as fruit, vegetables and oats. Thanks to their ability to bind water, they can regulate your bowel movements and support your intestinal flora.  <\/p>\n\n<p>Some of the most important properties of soluble fiber are:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>They dissolve in water and form a gel.<\/li>\n\n\n\n<li>They are mainly found in fruit, vegetables and oats.<\/li>\n\n\n\n<li>They support your intestinal flora and regulate your bowel movements.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Properties_of_insoluble_dietary_fibers\"><\/span>Properties of insoluble dietary fibers<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>Insoluble fiber, on the other hand, such as lignin and cellulose, is mainly found in whole grain products and is only slightly broken down by the intestinal flora. As a result, they retain their swelling properties and their influence on stool volume up to the rectum. <\/p>\n\n<p>Some important points about insoluble fiber are:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>They largely retain their structure during intestinal transit.<\/li>\n\n\n\n<li>They are mainly found in whole grain products, bran, nuts and the skins of fruit and vegetables.<\/li>\n\n\n\n<li>They act like a natural sponge by absorbing water and increasing stool volume, which stimulates bowel movement.<\/li>\n<\/ul>\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Abnehmen mit Ballaststoffen: Sie sind in diesen Lebensmitteln und gut f\u00fcr den Darm | ARD Gesund\" width=\"720\" height=\"405\" src=\"https:\/\/www.youtube.com\/embed\/vg554O3o0QA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Dietary_fiber_as_a_helper_in_the_intestine_how_it_works\"><\/span>Dietary fiber as a helper in the intestine: how it works<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>In the intestine, dietary fiber acts as a natural helper that promotes the movement of food pulp.

This effect ensures that the bowel is well filled and the muscles around the bowel are stimulated to transport the contents further. Your intestinal wall consists of two muscle layers &#8211; a longitudinal and a ring muscle &#8211; whose coordinated movement ensures the transportation of the food chyme through your body.  <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Dietary fiber serves as a natural training partner for these muscles by exerting a mechanical stimulus through its volume.<\/li>\n\n\n\n<li>The more fiber you eat, the better your intestinal muscles are trained and the more efficiently they work.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Influence_on_the_intestinal_muscles\"><\/span>Influence on the intestinal muscles<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>The positive influence of fiber on your intestinal muscles not only has an effect on digestion, but also supports general intestinal health and can prevent intestinal sluggishness. A low-fiber diet lacks this training stimulus, which can lead to a weakening of the intestinal muscles in the long term. <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Sufficient fiber intake is therefore important to strengthen the intestinal muscles and promote healthy digestion.<\/li>\n\n\n\n<li>By regularly consuming fiber, you can support the health of your intestines and prevent digestive problems.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_role_of_fiber_for_your_intestinal_flora\"><\/span>The role of fiber for your intestinal flora<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>Dietary fiber plays a crucial role in the health of your intestinal flora.
