One of the reasons it's so difficult to   study the relationship between diet and cancer

基礎受動態

is because many dietary behaviors are associated with non-dietary behaviors.

For example, the reason we used to think coffee-drinking caused cancer

was because people who drink coffee are more likely   to have a cigarette in the other hand.

When you factor that out though, for example, by looking   at just non-smokers who do or don't drink coffee,

we find that if anything, coffee consumption may reduce the total cancer incidence;

not by much, but overall, according to the latest review, an "increase   in consumption of one cup of coffee per day

was associated with about a 3% reduced risk   of cancers, especially bladder cancer, breast cancer,

mouth, colorectal, endometrial, esophageal, liver, leukemia, pancreatic, and prostate cancers".

But one is, after all, just soaking a   powdered seed in some water.

So a reduction in cancer risk?...not that surprising!
