The research studied 628 men aged 40 to 64 who had been newly diagnosed with prostate cancer, as well as 602 cancer-free men the same age.
Dr Kristal theorized that cruciferous vegetables, in particular, are high in substances called isothiocyanates, which activate enzymes that detoxify carcinogens.
Vegetables evolved mechanisms to avoid being eaten, such as cytochemicals
that are quite bitter and toxic, Dr Kristal explained. Continuing he said:
"Humans evolved the ability to detoxify these cytochemicals, and the enzyme systems that we use to detoxify cytochemicals are the same enzymes that detoxify naturally occurring carcinogens. We think the effect is by upregulating these enzyme systems that has a protective effect against cancer."
All men are at risk for prostate cancer but the risk becomes higher
as a man ages. Also, men who have had vasectomies have a significantly
increased risk of prostate cancer - some studies have shown the risk after
vasectomy, to be as high as 90 percent increased.
Most men are deficient in vegetable intake and especially veggies like broccoli (one of our former presidents was a famous broccoli hater). True, veggies taste like rabbit food and one may question, if they are so good for us, why God didn't make them taste like hamburgers or ice cream. However, studies for years have shown the good benefits of eating several servings of veggies a day. So eat your veggies and quit complaining! :)
