You'll get a hundred hits of people claiming something is bad and proven bad and most don't even bother citing anything but if you follows the ones that do cite down the 'proof' tends to be from either an iffy source or from a reputable one but says 'test results inconclusive, may have...' which is generally 'no, no significant threat has been detected' and people misunderstand 'no significant'.

So if 65 get cancer the scientist conclude nothing significant is happening but the populace concludes this stuff is dangerous. The problem is I could run two such samples, one on placebos and one on a gram a day of orange zest and get 47 and 67 and nothing has really been shown yet, but people will conclude the orange zest is like cyanide, and that will be hard to quash even if a subsequent study of 500 gets 38 people developing cancer. Take a hundred different foods and run one on each and even if they have no real danger to them you'll get several hit that 60+ range and some spiking over 70. That's just how the numbers game works. Others will be low 30's or even 20's and be labeled as anti-cancer.

I can't help but point out your link is rather low on citations from places like the USDA or Mayo and so on.
