Fibre, lignin and pectin: what's good for gut flora and digestion

Fibre, lignin and pectin: what's good for gut flora and digestion

Dietary fibre are an important part of a healthy diet. They are often used in connection with Intestinal flora, Digestion, saturation, fermentation and a fibre-conscious diet.

However, it is important to note that not all dietary fibres have the same effect. There are big differences between insoluble dietary fibres such as lignin or bran and soluble, fermentable dietary fibres like Pectin or Inulin.

This difference is particularly important for people who are concerned with intestinal flora, digestion, prebiotics and a healthy diet. It's not just the amount of fibre that counts, but also the type, quality and individual tolerance.

What is dietary fibre?

Dietary fibres are components of plant foods that are not or only partially digested in the small intestine. They continue into the large intestine where they can have different effects depending on the type.

Some dietary fibres mainly provide volume and structure. Others can be fermented by intestinal bacteria. This produces metabolic products that are considered in connection with the intestinal environment, digestion and short-chain fatty acids.

So the question is not just: „How much fibre do I eat?” But also: „What fibre do I eat, how well do I tolerate it and how does it fit into my overall diet?”

Lignin: structural dietary fibre with limited fermentability

Lignin is a plant-based structural substance. It is mainly found in woody plant parts, husks, bran and certain coarse plant fibres.

Lignin is one of the insoluble dietary fibres. It is difficult for intestinal bacteria to ferment and primarily provides structure. This does not mean that lignin is fundamentally bad. However, it differs significantly from soluble fibres such as pectin or inulin.

In animal feed and nutrition in particular, there is a debate as to whether very lignin-rich fibre sources really have the same value as finer, fermentable plant fibres.

Bran: high in fibre, but not ideal for everyone

Bran is often regarded as a high-fibre food. It contains mainly outer grain components and provides a lot of insoluble fibre.

For some people, bran can fit well into a high-fibre diet. Others are sensitive to coarse fibre, wheat components or large amounts of bran. Therefore, bran should not automatically be equated with well-tolerated, fermentable fibre.

Another point: the outer grain components are often associated with residues, storage, mycotoxins or raw material quality. This is why origin, control and processing are particularly important.

You can find out more in the article about Mycotoxins in cereals and healthy nutrition.

Pectin: soluble fibre from fruit

Pectin is a soluble dietary fibre that occurs naturally in many fruits. Apple pectin is particularly well known.

Pectin can form a gel-like structure when combined with water. It is often associated with intestinal flora, fermentation, satiety and digestion.

Unlike very coarse bran, pectin is a soluble fibre. This makes it particularly suitable for a diet that focuses on intestinal flora, digestion and prebiotic fibre.

You can find out more directly from the product Apple pectin with inulin.

Inulin: prebiotic dietary fibre

Inulin is also a soluble dietary fibre. It is often referred to as a prebiotic fibre because it can serve as a food source for certain intestinal bacteria.

Inulin occurs naturally in chicory, Jerusalem artichoke, artichoke, onion and garlic, among others. Inulin can be fermented by intestinal bacteria in the large intestine.

If you have a sensitive digestive system, inulin should be increased slowly, as you may initially experience bloating, a feeling of pressure or altered digestion.

Water-soluble and fermentable dietary fibre

Water-soluble dietary fibre such as pectin and inulin differ from predominantly insoluble dietary fibres such as lignin or coarse bran.

They can be fermented in the intestine by certain bacteria. This produces, among other things short-chain fatty acids, also known as SCFA. These short-chain fatty acids include acetate, propionate and butyrate.

These substances are often considered in connection with the intestinal environment, colon function, mucous membrane and metabolic processes. However, it is important to note that fibre is not a miracle cure. They work best as part of an overall healthy, varied diet.

Butyrate and short-chain fatty acids

Butyrate is a short-chain fatty acid that can be produced during the fermentation of certain dietary fibres. It is often considered in connection with the cells of the colon mucosa, the intestinal environment and metabolic processes.

Butyrate is also being investigated in connection with the gut-brain axis, immune processes and inflammation regulation. However, these topics are complex and should not be understood as simple promises of a cure.

The most important thing for everyday life is that a diet with sufficient soluble and fermentable fibre can create a different environment for the intestinal flora than a low-fibre diet with lots of highly processed foods.

Dietary fibre in animal feed

The type of fibre also plays an important role in animal feed. Not every fibre source is equally fermentable.

Soya meal, rapeseed hulls, rice bran or wheat bran differ significantly from finer plant fibres such as alfalfa or apple pomace. Apple pomace, for example, contains pectin and other soluble fibres.

For this reason, there is a debate in animal nutrition as to whether fibre sources should be evaluated not only according to their crude fibre content, but also according to their fermentability, pectin content and effect on the intestinal environment.

Glyphosate, gut flora and the shikimic acid pathway

Glyphosate is often discussed in connection with modern agriculture, GMO feed, residues, intestinal flora and the microbiome.

Glyphosate acts in plants via the so-called Shikimic acid pathway. This metabolic pathway occurs in plants, bacteria and some fungi, but not in human cells.

Researchers are therefore discussing whether and how glyphosate can play an indirect role via the environment, animal feed, food chains or the microbiome. The data situation is complex and should be considered in a differentiated manner.

For consumers, the most important practical conclusion is that food quality, origin, residues, organic products and minimising highly processed foods are useful points of reference.

Intestinal flora, LPS and sensitive digestion

The intestinal flora consists of many different microorganisms. Some of these are associated with fermentation and short-chain fatty acids. Others can form undesirable metabolic products in an unfavourable intestinal environment.

In this context, LPS, i.e. lipopolysaccharides from gram-negative bacteria, are sometimes also discussed. LPS is being investigated in the context of barrier function, immune reactions and the intestinal environment.

For a consumer-oriented categorisation, it is important that it is not a single term that is decisive, but the entire nutritional environment. Fibre, freshness, variety, good digestibility and as few highly processed products as possible all play a role.

Which dietary fibres are particularly interesting for digestion?

For a fibre-conscious diet, dietary fibres that fit well into your own nutritional concept and are individually tolerated are of particular interest.

Frequently discussed:

• Inulin
• Pectin
• Apple fibre
• Psyllium husks
• Oat beta-glucans
• Vegetable fibres
• Pulses, if they are well tolerated

Soluble and fermentable fibres in particular are often considered in connection with intestinal flora and digestion. However, if you have a sensitive digestive system, the amount should be increased slowly.

What does this mean for healthy eating?

For a healthy nutrition not only the amount of fibre is decisive. What is important is the total Nutritional qualityNatural foods, sufficient fluids, a variety of plant-based foods, good sources of protein and as few highly processed products as possible.

Highly processed foods often contain little fibre, but instead sugar, white flour, additives, refined fats or isolated protein components.

A fibre-conscious diet, on the other hand, focuses on more vegetables, fruit, pulses, nuts, seeds and specific soluble fibres such as inulin and pectin.

Fulvicherb products in connection with dietary fibre

Soluble and prebiotic fibres play an important role in Fulvicherb. Apple pectin with inulin combines two dietary fibres that are often associated with intestinal flora, fermentation and digestion.

Pure apple fibre may be of interest to people who want to make their daily fibre intake more natural.

Fulvicherb Synergy combines fulvic acid, arginine, inulin, pectin, niacinamide, herbs and other natural ingredients in a liquid formula.

These products are suitable for people who are interested in intestinal flora, digestion, fibre, prebiotics and a healthy diet and want to consciously supplement their diet.

How can you integrate more good fibre?

If you want to make your diet more fibre-conscious, you should start slowly. If you have a sensitive digestive system, increasing your fibre intake too quickly can lead to bloating or a feeling of pressure.

• Slowly increase the amount of fibre
• Drink enough water
• Carefully test soluble fibres such as pectin and inulin
• Integrate more fruit and vegetables
• Slowly introduce pulses
• Reduce highly processed foods
• Pay attention to individual compatibility
• Do not introduce several new sources of fibre at the same time if you have a sensitive gut

Frequently asked questions about fibre, lignin and pectin

What is dietary fibre?

Dietary fibres are plant components that are not or only partially digested in the small intestine. They are often considered in connection with intestinal flora, digestion, satiety and fermentation.

What is the difference between soluble and insoluble fibre?

Soluble fibres such as pectin and inulin can bind water and be fermented by intestinal bacteria. Insoluble fibres such as lignin mainly provide structure and are more difficult to ferment.

Is bran a good dietary fibre?

Bran is rich in fibre, but mainly contains insoluble fibre. Some people tolerate bran well, others react sensitively. The decisive factors are quantity, quality and individual tolerance.

Why is pectin interesting?

Pectin is a soluble fibre found in fruit. It is often associated with intestinal flora, fermentation, satiety and digestion.

What is inulin?

Inulin is a soluble prebiotic fibre. It can serve as a food source for certain intestinal bacteria and is often considered in connection with intestinal flora and fermentation.

What is butyrate?

Butyrate is a short-chain fatty acid that can be produced during the fermentation of certain dietary fibres. It is often considered in connection with the intestinal environment and colon function.

What role does glyphosate play?

Glyphosate is discussed in connection with modern agriculture, residues, animal feed and the microbiome. The assessment is complex and should be considered in a differentiated manner.

Conclusion: Not all dietary fibres are the same

Fibre is important for a healthy diet, but not all fibres have the same effect. Lignin and coarse bran are clearly different from soluble, fermentable fibres such as pectin and inulin.

The type of fibre, quality, quantity, fluid intake and individual tolerance are decisive for intestinal flora and digestion. Prebiotic fibres such as inulin and pectin are particularly well suited to a fibre-conscious diet.

If you want to be more conscious about your diet, you should pay attention to natural foods, sufficient fibre, good digestibility and as few highly processed products as possible. Apple pectin with inulin, Pure apple fibre and Fulvicherb Synergy can of course fit into a conscious nutritional concept.
