It is estimated that there are more bacterial cells in the body than human ones. Many of these bacteria perform vital roles in the gut, such as aiding digestion or preventing gastro-intestinal infection. There is growing interest in maximising the benefits the helpful bacteria that reside in the gut can provide. Probiotics, is the term used to describe a wide range of products that aim to do just that. So exactly what are probiotics, and how do they work? For answers to these questions read on….
Live bacteria have been used for thousands of years to produce fermented foods. This traditional method of preservation enhances flavour and texture to produce some of the most delicious Asian delicacies. Examples include kimchi, miso, soy sauce, nato, tamari, tempeh and soured milk. More recently the contribution that specialised live bacteria can make to improve the body’s health has also been recognised. These bacteria are commonly described as probiotic and can be found in a growing range of special supplementary foods or can be taken in the form of capsules. These products are designed to supplement the natural population of bacteria in the gut, conferring a number of potential health benefits. A Japanese company was the first in the world to realise the commercial applications of beneficial bacteria with the launch of a fermented milk drink in 1935.
