Promoting gut health: A guide
The gut is one of our body's most important organs. Among other things, it is responsible for the absorption of vital nutrients and for fighting off diseases. In this article, you will learn more about the functions of the gut and how you can influence gut health through your diet.
The importance of a healthy gut flora for your well-being
The gut flora, also known as the microbiome, has a decisive influence on whether we are healthy or ill. The composition of bacteria in the gut plays a crucial role here, as there are different types of gut bacteria. On one hand, there are "good" gut bacteria (e.g., bifidobacteria or lactobacilli), which promote digestion, produce vitamins, and ensure a pleasant sense of well-being; on the other hand, there are "bad" gut bacteria, which can cause bloating or digestive problems. "Bad" is in quotation marks, as these bacteria are also important for a symbiotic gut flora, but should not be present in excessive amounts.
An increased presence of these types of bacteria can in fact promote the development of various diseases. Through our lifestyle, we have an influence on which types of bacteria colonize our gut and in what amounts. A healthy gut flora can be supported, for example, through a conscious and balanced diet.
The following bacterial strains are contained in our Bio BioticFit:
- Bifidobacterium Lactis
- Bifidobacterium Bifido
- Bifidobacterium Infantis
- Bifidobacterium Breve
- Bifidobacterium Longum
- Lactobacillus Salivarius
- Lactobacillus Rhamnosus
- Lactobacillus Gasseri
Our Bio BioticFit combines these eight selected bacterial strains with natural vitamin C from acerola, which contributes to the normal function of the immune system, and pumpkin seed protein. The formula was developed especially for people with histamine intolerance and other sensitivities and can be easily integrated into everyday life. It is suitable for a low-histamine and low-fructose diet, is gluten-free, lactose-free, vegan, and free from unnecessary additives.
The gut: Functions and its importance for health
Our gut begins right at the stomach outlet with the small intestine, which absorbs the most important nutrients from food via the gastric mucosa. The remainder of the food then travels into the large intestine, where it is fully digested and excreted from the body via stool.
A healthy intestinal mucosa (mucosa) therefore plays an especially important role in our health, as almost all nutrients are absorbed through it.
Our HistaNutri MucosaFit also offers significant support for the gut and thus for health; it contains 11 essential nutrients that the organism requires regularly because it cannot produce them itself.
- Vitamin C from acerola
- Fennel
- L-glutamine
- Omega-3 fatty acids (ALA from flaxseed powder)
- Vitamin E
- Niacin (vitamin B3)
- Zinc
- Vitamin D and K
- Biotin
Intestinal mucosa
DAO (diamine oxidase) is located extracellularly in the intestinal mucosa. As a result, it is not well protected against external influences. Along with histamine N-methyltransferase (HNMT), it is one of two histamine-degrading enzymes, which is produced particularly in the small intestine and the placenta. It breaks down histamine ingested from food from the outside.
Fitting the topic of mucous membranes, our MucosaFit contains, among other things, biotin, which contributes to the maintenance of normal mucous membranes. The formula is supplemented by L-glutamine, zinc, fennel, as well as selected vitamins and other nutrients. MucosaFit is vegan and suitable for a low-histamine, low-fructose, gluten-free, and lactose-free diet.
Digestive enzymes
A calcium deficiency is noticeable through the following symptoms:
- Muscle cramps, muscle tremors
- Heart and circulatory problems
- Brittle fingernails
- Changes in skin and hair
Calcium is contained, among other things, in our FemFit; it was developed by women for women and, in addition to calcium, contains important nutrients such as magnesium, iron, and L-tryptophan.
Immune system
The "belly" is often referred to as the center of health, and quite rightly so. This is because by far the largest part of our immune system is located in the gut. Over 80% of immune cells are located in the gut and keep "bad" microorganisms in check so that they do not multiply excessively. In this way, these bacteria keep the immune system constantly active. In contrast, "good" gut bacteria inform the immune cells in the gut about intruders so that the immune system can become active immediately. If there are not enough "good" gut bacteria in the gut, this can lead to gut flora dysbiosis and consequently to a weakening of the immune system.
Histamine degradation and its importance for gut health
Due to impaired gut health, diamine oxidase (DAO) cannot function properly, which causes too much histamine to accumulate in the body, which can lead to a wide variety of symptoms. This means that people with a DAO deficiency have an increased risk of suffering from a histamine excess. The most common symptoms of a DAO deficiency include headaches, diarrhea, constipation, or fatigue.
The role of diet for a healthy gut flora
Our gut is the totality of our gut bacteria. In a healthy gut, protective or "good" bacteria should predominate. Furthermore, there should be a high diversity of gut bacteria in the gut, which allows the gut to better respond to changing living and dietary conditions. That is why a colorful, varied diet is the be-all and end-all for a healthy gut, because the more diverse our diet is, the more diverse our gut environment is as well. Here, however, it should be noted that not all foods that are healthy for the gut are also suitable for a low-histamine diet.

Low-histamine diet: Foods that should be avoided
- Sauerkraut
- Alcohol
- Ham and sausage
- Tomatoes
- Eggplant
- Sourdough
- Citrus fruits
- Long-aged cheese
- Cocoa
- Industrial sugar
- Convenience products/highly processed products
What role do dietary fibers play for the gut flora?
- Resistant starch: grains, tubers, cooked and subsequently cooled starchy products like potatoes or pasta
- Pectin: types of fruit such as apples, quinces, or apricots, types of vegetables such as carrots
- Beta-glucan: oats, barley (1)
- Inulin: asparagus, parsnips, Jerusalem artichokes, chicory, or onions (1)
- Cellulose: vegetables, whole grain cereals, oat bran
- Hemicellulose: psyllium husks, wheat bran
- Lignins: nuts, cabbage vegetables, root vegetables such as carrots
Long-term measures for healthy gut function
The following measures can ensure healthy gut function in the long term:
- Fiber-rich diet: Fiber sources like coconut flour, potatoes, or chia seeds are excellent
- Adequate exercise also ensures long-term gut health, as it stimulates digestion and helps the gut to "sort itself out."
- Drinking enough water is just as important, as providing the body with sufficient water not only helps the body with better digestion but also leads to optimal functioning of all organs overall.
- It is equally important to sleep sufficiently and effectively, as sleep disorders very often affect digestion.
- It is also important to reduce stress as much as possible, as stress hormones activate nerve cells in the intestinal wall, causing symptoms such as diarrhea, constipation, or bloating.
Conclusion: Gut health as the foundation for your well-being
In conclusion, one can say that it is very important to pay attention to a functioning and healthy gut flora, as the gut is responsible for our entire health, and if it cannot properly bring nutrients into our body, it makes us ill in the long term.
Would you like to sensibly supplement your low-histamine diet in regard to gut health?
