Fiber is an incredibly important part of a healthy diet. And although the word itself, and especially the part “fiber,” sounds rather negative, these components of food are extremely beneficial. But what is fiber, what exactly is so great about it and where is it found? With our help, you will soon understand all of this as well as the pros and cons of proteins, unhealthy fats, carbohydrates and vitamins, which most people already understand more about. You will also receive tables with lists of high-fiber foods.

What are fiber and are they healthy?

Dietary fiber and fiber-rich foods create a balance in the gastrointestinal flora

The question is actually answered relatively quickly and easily: Dietary fiber is the part of plant products that humans cannot or can hardly digest. They are also called polysaccharides. They include, among others: Cellulose (fruit, vegetables, cereals), pectin (Fruit), bran (cereals) or the Gels from the edible seaweed. This explanation will probably make you stunned at first. Why are they good fibers if the body ultimately doesn’t benefit from them because they are excreted unprocessed? What are they good for?

Why are they important?

The natural bacteria in the intestine feed on fiber and thus do not attack the mucous layer

Indigestible fiber balances the intestinal flora, which prevents problems with digestion and the digestive tract. Above all, the risk of constipation or intestinal diseases is reduced. Studies have also shown that foods rich in fiber are good for blood pressure and cholesterol levels and have a positive effect on insulin levels. Fiber is divided into soluble and insoluble. Why do we need fiber from both groups?

Foods rich in fiber and fiber stimulate digestion and cleanse the gastrointestinal tract

What are the soluble versions needed for?

Soluble fiber includes pectin, inulin and oligofructose. They bind water and thus act as a swelling agent. The bacteria living in the large intestine process the substances into important fatty acids and gases. This means that the stool not only becomes softer, but also more. This prevents constipation and also improves the regularity of bowel movements.

The bacteria are an important component for a healthy and well-functioning intestinal flora. Since these bacteria feed on the fiber, they can multiply well. A healthy intestinal flora is therefore the result of a proper diet with sufficient fiber.

Here you can learn more about soluble fiber in a low-carb diet.

The pectin in apples and especially in the peel is a great fiber

Why does the body need fiber that is not soluble?

The insoluble variants, on the other hand, bind much less water. But that doesn’t mean that they are less or not useful at all. On the contrary, they ensure that the volume of the stool increases even more, which in turn stimulates the intestines. Its movements improve. Better transport of food residues and faster excretion are the positive consequences of this.

It is therefore important that you eat enough fiber for many reasons. Because if your digestion is balanced and your intestinal flora is healthy, many diseases and gastrointestinal problems can be prevented. It is interesting to note that the natural bacteria in your intestines feed on these nutrients. If they do not receive this food, they are forced to feed on the mucous layers of your intestines. This is a kind of cannibalism.

Eating high-fiber foods – how much is recommended?

Fiber and fiber-rich foods are good for the stomach and intestines

Nutrition during pregnancy - Which nutrients are particularly important

The German Nutrition Society (DGE) recommends 30 g per day. These are best consumed in several meals throughout the day. And the high-fiber diet is extremely varied, so you have a wide choice and can change high-fiber foods regularly. This way, a balanced diet can be guaranteed.

If you have only consumed an amount below the recommended amount and would like to increase your intake, you should do so slowly. Too much fiber in a very short period of time can lead to bloating or a feeling of fullness. This is simply because your body is not used to it yet. Also, don’t forget to drink enough. This is the only way for the substances to swell and be flushed through the body.

Where does fiber come from?

Eat a varied diet with vegetables, fruits, grains and other fiber-rich foods

So you have decided to make sure you regularly eat fiber-rich foods. But where is fiber found? Especially fiber-rich foods are the fruit and vegetables and the fact that these foods should be on the table every day is nothing new. So if you previously believed that fruit and vegetables were only healthy because of their vitamins, that was not entirely true.

The advantage of vegetables over fruit is that they have less sugar, which makes them even lower in calories. Nevertheless, you should definitely not avoid fruit, because it contains many beneficial ingredients that the body also needs.

Fiber is found in various foods and should be part of the daily diet

Also whole grain products are high-fiber foods. You don’t have to eat these in addition to your usual grain products, but you can simply replace all wheat products, be it bread, rolls or pasta, with whole grain ones. Spelt is just as suitable as whole grain.
