Billions of little helpers
Although you can’t see them, we have hundreds of billions of bacteria called the microflora (or microbiome) living on our skin, in our mouth and nose and most notably in our intestines. This microflora weighs around 1.5 kilos (the same weight as our liver) and is estimated to account for around 2% of total body mass.
These bacteria outnumber our cells by about 10 to 1 and take residence in our bodies from the day we are born, remaining with us throughout our lives.
The human gastrointestinal tract has developed with a very complex but stable population of bacteria that play an important role in nutrition, metabolism, regulation of immune function and protection.
The beneficial bacteria are made up of hundreds of different species, the main two of which are Lactobacillus and Bifidobacteria. These bacteria are found in the normal microflora of the intestine and research shows that they play an important role in improving digestion and intestinal health as well as helping to regulate the immune system.
