The Benefits and Non-benefits of Caffeine and Soy, Part 2

The good news is that

caffeine is found to have 60% lower risk for the lethal and advanced prostate cancer.

“Coffee has effects on insulin and glucose metabolism as well as sex hormone levels, all of which play a role in prostate cancer,” said researcher Dr Kathryn Wilson.


On the other hand, soy products were once considered to be contraindicated for women with breast cancer. This is because soy products are high in plant estrogen and this counteracts with the antiestrogen effects of tamoxifen.

However, new research reveals that in a study that involved 5,000 Chinese breast cancer survivors, those who had the highest intake of soy foods (more than 15 grams of soy protein a day) had about a 30 percent lower death rate and nearly a 30 percent lower rate of recurrence than those who ate the least amount of soy. That’s probably because soy also contains compounds that have anticancer effects.

In other words, it’s safe to eat soy products if you have breast cancer.

The study, though, didn’t find any extra benefits from taking more than 15 grams of soy protein a day.

So while soy can help, it is not curative.


I’m no smoker, but I wonder what benefits smoking has…
