Gewusst? Zehn spannende Fakten zum Darm
- The human intestines (gut) are around 8 metres long.
- The gut is the largest human organ. If you were to lay out the umpteen tiny folds and villi in the intestinal wall, the surface area of the gut would extend to 300 to 500m2. By way of comparison, the entire surface of our skin doesn't even come to 2m2, and a doubles tennis court is around 260m2.
- Thousands of strains of different bacteria live in the human gut and form the natural gut flora. They make up a large part of the human microbiome. The microbiome is all the microorganisms living on and in every human being. It's increasingly believed to play an important role in individual health and disease. All these bacteria together weigh around two kilos.
- A healthy gut flora strengthens the immune system, because 70% of the defence cells of the human immune system are located in the gut.
- Stress or taking antibiotics can throw the gut flora out of balance.
- Probiotics have a positive influence on the gut flora. These are bacteria that have a health-promoting effect. They help keep the gut fit.
- A healthy gut also likes to rest. It's important for it to have a break of several hours between meals. If you're constantly eating, the intestinal bacteria have food all the time and can multiply (depending on what's eaten, unfavourably). So a break of four hours is recommended between main meals and a break of twelve hours overnight.
- The gut is also known as the seat of intuition. After processing and evaluating sensory impressions and thoughts, it reports them to the brain.
- There are 100 million nerve cells in the digestive tract, more than in the spinal cord, so there's very good reason for the term "abdominal brain".
In the course of an average lifetime, a gut processes about 30,000kg of food and over 50,000litres of fluid.
What throws the gut flora out of balance
A healthy gut isn't only important for good digestion, but also for the immune system and our mental wellbeing. There are a number of things that can throw a healthy gut flora off track.A common cause of intestinal discomfort is antibiotic drugs. In 2021 alone, almost one fifth of the Swiss population took antibiotics, used in human and veterinary medicine to combat bacterial diseases. Antibiotics attack not only bacteria that cause diseases, but also the body's own precious intestinal bacteria. Other medicines can also cause unexpected and undesirable side effects in the gastrointestinal tract.
Unhealthy diets such as too much sugar, alcohol or high-fat food can also have an unfavourable effect on the intestinal flora.
Stress is also harmful to gut health.
Other medicines can also cause unexpected and undesired side effects in the gastrointestinal tract. For our digestion to work well, various glands (for example the salivary glands) and organs (such as the gall bladder and pancreas) and the intestines themselves must work well together. The various digestive juices our body produces and the millions of intestinal bacteria break down our food. This allows important nutrients and fluids to be released and absorbed, and other, unusable food components to be transported out of the body in the stool. Breaking down food and transporting the food pulp are equally important functions. If one of them doesn't work properly, problems such as gas, bloating, pain, constipation or diarrhoea may occur. Intestinal bacteria also help the intestinal mucosa to stay healthy, protecting it from inflammation and from developing intolerances. To do this they must be available in large quantities and in as great a variety as possible.
The intestine is an organ that does an incredible amount of work through a lifetime and needs recognition and care in return.
«Most people know their digestion and their own personal digestive habits. The gut likes to have rituals, but they don't have to be the same for everyone. If you notice changes, there's often something out of balance. In the event of mild symptoms, first of all it's a good idea to do something for your gut flora and support your efforts with a healthy mixed diet. If the pain becomes more severe and the changes persist, you should have this checked out by a doctor.»
So wird der Darm wieder fit
It makes sense to actively do something for the health of your gut and thus indirectly for your health as a whole. A wholesome diet facilitates the development and maintenance of a healthy gut flora. Even small changes in your diet make a big difference. There are some foods that naturally contain beneficial bacteria. Probiotics are preparations made of good bacteria that stimulate growth. They help revitalise the gut flora and get the intestines fit. There are around 400 probiotic bacteria. One of the best known is the lactic acid bacterium, which is very acid-tolerant and thus survives the passage through the stomach and can settle in the gut.
The following foods contain probiotic bacteria:
The following foods contain probiotic bacteria:
- Plain yoghurt
- Kefir
- Buttermilk
- Quark
- Sour milk
- Sauerkraut
- Miso (Japanese seasoning paste)
- Gherkins
- Kombucha (fermented tea)
- Apple vinegar
- Cheese
- Tempeh
- Kimchi
Prebiotics also have a healthy effect on the gut. Prebiotics are dietary fibres that are not digested by the body and promote the growth and activity of bacteria in the colon. Inulin and oligofructose are two prebiotics from plant ingredients. Whole grain products and vegetables contain more fibre and are therefore good for the gut.

Nutritional tips for a healthy gut
- Take your time when eating and chew your food thoroughly. If you chew each bite fifteen to thirty times, the food is optimally crushed and mixed with saliva. The stomach doesn't have to do extra work and can devote itself to what it's supposed to be doing.
- Leave gaps between meals. Constant snacking overloads your gut. It needs breaks to regenerate. In concrete terms that means a gap of around three to four hours between meals; overnight you can even take a break of 12 to 16 hours.
- Enjoy sugar in moderation. Many products you wouldn't expect actually contain sugar. Deliberately cut down on sugar because it can have a negative impact on your gut flora.
- Wholemeal has a positive influence on the gut flora, so choose wholemeal rather than white flour products.
- Virgin colada and alcohol-free beer at the weekend. Alcohol can cause digestive problems such as belching or even diarrhoea. Like sugar, it also has a pro-inflammatory effect.
- No fast food. High-fat food is heavier on the stomach and harder to digest. Depending on the composition of the gut flora, fat digestion functions differently from person to person.
If the change in diet alone isn't enough to build up the gut flora, there are also a variety of probiotic preparations that also support the process. Here it's advisable to seek advice from a doctor or pharmacist.
