      Hi muthambulwan
      I read somewhere that we have 10 times more bacterial cells in our body than human cells. Bacteria is a part of our lives and in many cases it does good things for us. For example, when we digest food we need ‘good’ bacteria to help break it down and help our digestion. There is usually a balance within us where certain levels of bacteria can be beneficial. The problems occur when they are allowed to reproduce and thrive too well. This is when we can get an upset tummy or can feel generally unwell.
