A healthy intestinal flora has a positive effect on general well-being. A Mediterranean and predominantly vegetarian diet is recommended.

Excessive consumption of sausages and processed meat can damage the intestinal flora and hinder weight loss. Fructose (fruit sugar) can lead to stomach and intestinal problems and trigger an inflammatory reaction in the intestines. Large amounts of animal protein - for example in cheese, meat, eggs and milk - can be harmful and lead to inflammation. Industrial cooking oils that are rich in omega-6 fatty acids can promote inflammation in the body, including the gut.
