What I'm giving you here is a chance to climb the ship's mast with me so that from its top we can see far over the horizon of medicine. The view from the masthead is based not so much on my daily activities as a practicing physician but on my mission to search the seascape of scientific research for courses that can help prevent my patients from developing prostate trouble. What I see from the top of the mast is a body of evidence that is solid enough to support these simple changes in behavior, especially considering that there's zero risk in consuming flaxseed and soy protein.
The best evidence is based on studies done in a couple of places in the world, where prostate troubles are rare. Solid epidemiological studies that show a lower incidence of prostate cancer in men consuming foods popular among Finns and Chinese — rye bread for Finns and soy for Chinese.2 And he has carried out elaborate chemical analyses and experiments to show which substances in these foods provide the protection.
For years before his research was done, it was assumed that the Finns' genetic history accounted for their lower incidence of prostate cancer. Most modern Finns come from a small number of people who migrated to that part of the world many years ago, so they are a rather distinct linguistic, racial and genetic group. It turns out, however, that it's not their genes but their diet that protects them against certain cancers. And the dietary factor that is most significant is a sourdough rye bread that is eaten by people consuming a traditional Finnish diet. This whole-grain, heavy- duty bread is made out of ground whole rye seeds without anything removed. The leavening is provided by lactobacillus (acidophilus) instead of yeast, which is used to leaven almost all bread consumed in other parts of the world. What's key is that the rye fiber contains lignans that modulate hormone chemistry and reduce the risk of reproductive cancers.
Eastern Europeans have traditionally used flaxseeds as a source of food and medicine. Flaxseed oil, which makes up about one-third of the weight of the seeds, has extremely healthy properties that also provide particular benefits for the prostate gland. But here we're talking about the fiber in the flaxseed. The best way to use the seeds is to grind them in a coffee mill. You can then consume the fine, fluffy powder as part of a shake or add it to a variety of other foods. Your aim is to eat a heaping tablespoon per day.
Besides rye and flaxseed, there are other foods that contain lignans. Some of the best sources include legumes (especially lentils, kidney, fava and navy beans), seeds (like sunflower seeds), seaweed, cereal brans and whole grains.
There is also a solid body of evidence supporting the role of soy protein in reducing the risk of prostate cancer. For example, research has shown that isoflavones, substances contained in soybeans, modify testosterone metabolism, decreasing the risk for both benign prostatic hypertrophy and prostate cancer.3 Incorporating soy protein in your diet doesn't require you to change what you eat, although it's fine to eat more tofu, miso and other soy products if you enjoy them. The simplest, quickest way to consume soy protein is by stirring soy protein isolate, a relatively tasteless substance, into some of the food you are already eating.
Foods like soybeans, flaxseed and rye contain information derived from phytonutrients, which keep animals in synchrony with the rhythm of the seasons and which have profound effects on our own reproductive systems.
Prostate Inflammation or Nonspecific Prostatitis
Your prostate gland usually doesn't speak to you until it's in some advanced state of trouble. When it does, it has only two voices. One is expressed through pain or difficulty with urination and the other is just plain pain, which is almost invariably felt in the midline of your body. The spectrum of difficulties includes inflammation, enlargement and cancer. While there are more or less pure representations of each one, the lines between them are often blurred. All three, but particularly enlargement and cancer, are addressed by the preventive measures included in the Body Clock Diet.
Let's start with inflammation, which is the medical term for some combination of redness, pain, swelling and heat that almost always accompanies infection but may also represent your body's reaction to noninfectious irritants or allergens. The flame of prostate inflammation is experienced as burning with urination. This is as much a result of inflammation of the tube through which the urine passes out of the penis (the urethra) as it is due to inflammation of the prostate, per se, which lies astride this tube, just beneath the bladder. Germs that infect the urethra, such as the gonorrhea germ, may ascend it and get into the prostate gland. There, the alkaline environment and blood supply, which are conducive to bacterial growth, make it much harder to treat the infection with antibiotics than, say, a sore throat, a boil or an uncomplicated pneumonia. Because the germs that infect the prostate are difficult to extract from apatient for a culture it has become a common practice for doctors to treat symptoms of prostate inflammation with antibiotics without knowing what germ, if any, might be there.
The diagnosis in this situation is 'nonspecific' prostatitis, which is a well- accepted medical term. But when you stop to think about it, it's peculiar. According to medical principles, when there is an infection, the perpetrator is almost always a particular germ. The prostate, like all internal tissues, is not likely to be infected by more than one germ at a time. The implication is that if there's an infection, it's quite specific. How then do we come up with the diagnosis 'nonspecific' prostatitis? It's a result of several factors; efforts to recover a germ are to no avail, the prostate acts as if there's an inflammation — with swelling, pain, difficulty urinating and sometimes cloudy or pussy urine — and antibiotics are at least temporarily soothing. But after antibiotic treatment, this problem recurs more often than other infections.
