Remember how we’ve been told repeatedly to wash our hands frequently? The idea behind this is to remove from our body any potential pathogens (bacteria, viruses and parasites) that we may have come into contact through touching objects and people around us, or through droplets that have been released into the air when someone sneezes. Indeed, bacteria can be spread around and transmitted through multiple ways in the environments that we live in. The bad ones can cause diseases or spoil food, and can sometimes be life-threatening. Despite of the bad, there are the good ones that sometimes we have forgotten about. Good bacteria are not only important to our health but can also have an impact on our diets and lifestyles.
