IN THE furore over various E-Coli outbreaks – with the blame being attached to cucumbers and beansprouts – it has been overlooked that an additive, polysorbate-80 – a fat emulsifier used in processed food – according to Liverpool University, helps the movement of bacteria through human body cells.

This includes E-Coli, which may explain why Third World countries have little or no ulcerative colitis or Crohns, but does not explain why such additives are added to our food.
