A few years back there seemed to be a plethora of studies which were "Consuning <insert hot liquid> increases chance of throat cancer".
You would have to go to the source report (if lucky the bottom of the article) to find out it increased the risk by 0.1% - 0.5%.
When you factor in only 2,300 people in the UK (70 million) get throat cancer each year and the biggest risk factor was smoking and non smokers are pretty much within statistical error bars.
It makes the report uninteresting and only useful in a "someone already looked into this" way and yet a month would go buy and there would be a new article .. who knew chicken soup causes cancer...
