The Dannon Company has conducted a telephone interview survey to identify the need for its new probiotic yogurt, Activia, in the US.


The survey, called The Activia Most Irregular Cities Ranking, identified Orlando, Florida, as the most ‘irregular’ market in America.


Yoghurt specialist Dannon termed irregular as not visiting the lavatory for two or more days.


Evidence showed that around 26 million American adults have experienced such irregularity in the past three months, with 55% of those people having the condition three or more times during the three months.
