1) You can't see what the legend is in the FB preview or what the chart shows. I guessed what it was from the data. Coffee was the big clue I've noticed every six months something comes out that says it's either pro or anti cancer with perfect odd parity.

2) Up to 90% (depending on the area) of medical studies are wrong: http://www.theatlantic.com/magazine/print/2010/11/lies-damned-lies-and-medical-science/8269

Also: " 47 out of 52 milestone cancer studies can't be reproduced "

3) You can always tell when people don't know anything about cancer when they say the words "causes cancer". Cancers form naturally and can be found in all living things, it's simply where cells don't divide properly. The immune system kills these nearly all the time. Certain foods either attenuate or enhance that process.

The most extreme example was the grapefruit study that showed they "cause" cancer. All citrus are profoundly anti-cancer as they contain the highest amount of the phytoalexin used as the primary raw material the body uses to kill cancer cells. It was simply a fluke and more symptomatic (no pun intended) of bad methodology. "people who eat grapefruit" or. "people that do not eat grapefruit" is pretty meaningless if they didn't notice for example that only the grapefruit eaters smoke and work in asbestos factory. But they don't look at that, it's either "eats grapefruit" or "doesn't eat grapefruit". There is simply no control.

Wose, this is only correlation they ignore causation. It's nearly all junk science.
