For most it isn't easy unless you've been around the study business and spent lots of time in the world they're studying. In this case Type 2 diabetes.
The first thing you know all studies have an agenda, though the people involved will deny it. The second thing you want to know is who funded it.
The third thing is how they arrived at the magical number nearly all studies spout. Again, in this case 22%.
The next thing you know every study needs a quote from a so-called expert. And an independent one all the better. This time a statistical one who overwhelms us with the brilliant line:
"The bottom line is that sugary soft drinks are not good for you - they have no nutritional value and there is evidence that drinking them every day can increase your relative risk for type 2 diabetes," he said in an emailed comment.
Can and relative are interesting choices to describe your everyday risk. Driving on a California freeway everyday can increase your relative risk having an accident too. And we'll put our evidence up against his any time.
The tip off in this study is: "Fruit juice consumption was not linked to diabetes incidence."
That tells you fruit juice makers are not the bad guys--yet. Next time you buy a bottle or can of fruit juice check out how much sugar it contains, if you can.
If you check online you'll see this story was picked up by ABC News and blasted over other outlets.
