"All diseases begin in the intestines." Hippocrates already knew that.
If you look at the latest results from the field of microbiome research (scientific examination of the intestinal flora), you understand how right he was.
A large number of diseases are associated with a disturbance of the intestinal flora.
Through a conscious diet, the intestinal flora can be changed every day anew with amazing effects on our well-being and health. I would be happy to advise you in detail on this.
