Prostate Cancer: A Growing Disease In Men

Adapted from Dr. Fuhrman's book Disease Proof Your Child:

The studies examining the link between obesity, body size, and prostate cancer have focused on adult Body Mass Index (BMI). The results of these studies have not been conclusive; some studies have found a direct relationship and others have not.1 When looking carefully at tallness versus obesity, there is an apparent link between prostate cancer and height, but not with obesity. This is probably because extra fat on the body results in a higher estrogen/progesterone ratio, and it is the higher testosterone/estrogen ration that promotes prostate cancer. Therefore, the earlier attainment of adult height is more closely related to prostate cancer risk, not merely being overweight. Men over seventy-one inches tall were observed to have a 32 percent increased risk of prostate cancer. The conclusion is that the dietary style that is most growth promoting also promotes a higher level of testosterone in childhood that is linked to later-life prostate cancer.2

It takes at least one generation for men in immigrant families coming to America to assume the cancer risks of their host country, suggesting the importance of early-life factors.3 Similar to early puberty in females, earlier attainment of adult height and early onset of beard growth in males is a marker of increased risk of prostate cancer.4 Men's diets as toddlers and children most powerfully affect the age when they mature and develop facial hair. The prostate gland is essentially a dormant organ until puberty (much like the female breast), when heightened testosterone levels stimulate its development.

The data on prostate cancer causation points to higher testosterone levels beginning at an earlier age in childhood and throughout puberty as having a strong effect on later occurrence of aggressiveness of prostate cancer.5 Furthermore, studies demonstrate that prostate intraepithelial neoplasia, a cancer precursor to lesion, is already common in men in their twenties and thirties, suggesting that the process of carcinogenesis begins early.6

Prostate cancer is the male version of breast cancer. The genetic predisposition is illustrated by the fact that families with a strong history of breast cancer have an increased risk of prostate cancer in their male offspring and vice versa. So the early nutritional environment we grow our children in creates the favorable soil to fuel the breast cancer and prostate epidemics. The same dietary factors that heighten estrogen levels in females raise testosterone levels in males.

When the death rates for prostate cancer and testicular cancer were examined in forty-two countries and correlated with dietary practices in a carefully designed study, they found that cheese consumption was most closely linked with the incidence of testicular cancer for ages twenty to thirty-nine, and milk was the most closely associated with prostate cancer of all foods.7 Meat, coffee, and animal fats also showed a positive correlation.

Gee, maybe Pfizer/Merck/Glaxo/Novartis...can develop something called about...Prostatin...that blocks the production of Prostatic Alk Phos (but doesn't do anything to lower prostatic cancer risk) and get some "researchers" (KOLs=Key Opinion Leaders) at Mass General or Johns Hopkins to rubberstamp a "research" article which happens to be REALLY authored by a medical "ghostwriter"...
Sorry for the sarcasm, but I am RE-reading Abramson's Overdosed America and getting increasingly cynical about the medical establishment's capasity to address the real heath problems our population faces.

Anet needs to just understand : Relatively speaking there is no large money in produce. There is large money in pharmaceuticals, meat, dairy, gastric surgery, lifetime diabetic supplies and oversized caskets. It is really quite simple. The solution? Teach our kids to critically think for themselves. Just look. Follow our long intestines to the truth. Regards to all. Peter Bircsak
