The human body is home to trillions of tiny organisms such as bacteria, viruses and funghi. These tiny organisms, make up our microbiota and most of them (about 95%) live in our gut. The combination of microbiota, the products it makes, and the environment it lives within, is called the human microbiome.
The microbiome is linked to our health. Research has found associations of the microbiome with obesity, colorectal cancer, diabetes, celiac disease and irritable bowel syndrome.
This explains why there is a great emphasis on creating or maintaining a healthy gut and feeding the good bacteria. This can be achieved by having a high fibre diet (i.e., fruit, vegetables and whole grain) and eating fermented foods such as kimchi, sauerkraut and yoghurt, while removing excess fat and sugar from your diet.
