I respect Dr. Leibowitz, but I'm convinced his evidence is weak. I get 200 mg of soy daily.
200mg or 1/5 gram per day to affect prostate cancer risk? Isn't that less than a single soybean per day? Or do you mean specifically the soy isoflavones?

Yes! I'm sorry if there was any confusion about this. I guess I've slipped into verbal shorthand, saying and writing "soy" when I mean "soy isoflavones." The meaning is very clear when you've been dealing with these nutritional elements for prostate cancer for a long time, but it could well be confusing to newcomers, which we all were at one time. It's good to have someone experienced take a fresh look at what we are all posting from time to time and to catch things like this. I'll try to use "soy isoflavones" in the future. At least someone looking for food or a supplement would probably find it impossible to find a source of just 200 mg of soy itself. I can just visualize someone chomping on part of a soy bean daily.
However, your point about the doses for prevention does raise the point that some elements can do their work at very small levels, so it's important to understand the dose. One of them is selenium (yeast based), which appears to be beneficial against prostate cancer at just 200 mcg (micro grams) daily. It's fairly hard to get that dose from food, but a couple of good sized Brazil nuts, if grown, harvested, marketed and consumed in a way that creates and preserves potency, will provide that dose, as will a few other foods. (There is some concern that selenium may not be advisable for those having or prone to diabetes, though the current evidence is not strong and the adverse impact, if any, is not thought to be great. Some doctors are advising such men to not use selenium as a supplement.)
