The intestinal flora of every human being is highly individual. The microbiomes differ in the number of bacterial species that are found in the intestine. So far, it has been assumed that a large variety of species is beneficial to health. The good news is that the microbiome changes in the course of life and that nutrition plays a role in this. The less good news is that it ist not easy to follow a healthy diet.
Probiotic foods such as yogurt or sauerkraut, kefir and kimchi contain microorganisms and their consumption can be good for the intestines. A diet rich in fibre such as lentils, blueberries and apples can also help. Foods containing polyphenol also have a positive effect. This plant substance is contained for example in green tea, broccoli and almonds. However, this does not mean that eating these foods automatically leads to a healthy intestinal flora with the right microorganisms.
Not everyone needs the same substances in the same quantities to build up a healthy intestinal flora. It can even be the case that the microbiomes of two people are very different and yet both have a healthy intestine. That is why different people need different things to support their intestines. The best way to support the microbiome in your stomach is by first finding out what its condition actually is like.
