Producer's Response

Here is what the producers of I'm A Celebrity are saying about the Heidi "torture":

ITV Studios, producers of the series, state that press reports at this time are untrue. ITV has been producing this format around the world for many years and the health of the celeb participants are of the utmost importance. A medic and a doctor are present at the location at all times for all participants. All allegations of the celebrities being deprived of food and water are completely untrue.
