Has any food item really been studied & recommendations made more than coffee? Check back in a couple of years, there will be different studies & recommendations. 

It seems whenever someone dies from ailments vs being shot or in a fatal accident of some type, then food items are often scrutinized & criticized.

I'm not really sure you can control everything in the world with diet.
