Prostate Cancer and the
Diet for Prostate Cancer
 Every
year prostate cancer killed 31,500 American, One of every six American will be
diagnosed of prostate cancer in his lifetime.
Suggested diet:
- 1). Eat less red
meat ( beef, pork, lamb, or veal). Harvard researchers reported that men who
ate red meat (beef, pork, lamb, or veal) most frequently had more than
double the risk of advanced prostate cancer compared to men who ate those
meats least often.
The Sun For
Vitamin D
- 2). Don't take
calcium more than 2,000 milligrams a day. Vitamin D may protect the
prostate. However, it’s safe to have Recommended Dietary Allowances (RDAs)—1,000
mg a day for men 50 or younger and 1,200 mg for men over 50.
- 3).Take selenium
(200 micrograms a day, such as high-selenium yeast) and vitamin E (400 IU of
alpha-tocopherol) daily might lower the risk of prostate cancer in healthy
men. NIH is launching a 7- 12 years clinic study of prostate cancer
prevention (SELECT -Selenium and Vitamin E Cancer Prevention Trial). To be a
volunteer, you must have a PSA no higher than 4 and must be at least 55
years old (at least 50 if you’re African American). For more information,
call the NCI’s Cancer Information Service (1-800-4CANCER).
- 4). Eat
tomato-rich meal at least twice a week. It has been found a higher blood
lycopene levels in men can low risk of prostate cancer. Men who consumed
tomato sauce two to four times a week had a 34 percent lower risk of
prostate cancer than men who ate no tomato sauce.
- 5). Eat more soy
products and take soy isoflavones supplement. The isoflavones in soy inhibit
the growth of prostate cancer cells in animals study and people in Asia who
consumed soy product as regular food have low prostate cancer incidence.
- 6). Consumer fish
three to four time a week to replace red meat. Try to take omega-3 fatty
acid supplements (deep sea fish oil). Latest study showed that the men who
consumed more fish—especially deep sea fish (Salmon and tuna) —had a
lower risk of prostate cancer. these fish are good sources of fats and seem
to be protective.
- 7). Eat more
vegetables, fruits, whole grains with different colors (that indicate their
content of specific phytochemicals that have preventive health benefits),
eat less meat and animal fat may help for cancer.
Prostate Cancer Risk
Factors
As with any cancer,
prevention is the best approach. Of course before we can pursue prevention, we
must know contributing factors. Let’s look at some of the risk factors with
prostate cancer.
The first risk
factor is something we can do nothing about: age. Prostate cancer is extremely
rare in men under the age of 50 and rates increase exponentially after that. In
1992, the rate per 100,000 was as follows.
- Age Incidence
- 50-54 4
- 60-64 37
- 70-74 166
Genetics play some
role in risk of prostate cancer. Specifically, around 9% of prostate cancers
appear to be familial.
The male hormone,
testosterone, and its analogues are definitely involved in the pathogenesis of
prostate cancer. The National Cancer Institute lists the following as support
for the role of male sex hormones in prostate cancer.
|
|
Neither benign
prostatic hypertrophy (BPH) nor prostate cancer have been reported in men
castrated prior to puberty. |
|
|
Many studies
have shown that populations with higher levels of testosterone and most
importantly dihydrotestosterone have higher incidences of prostate cancer.
For example the highest levels are found in blacks males, intermediate
levels in white males, and lowest levels in native Japanese. The incidence
of prostate cancer parallels the levels. |
|
|
Deprivation of
androgens (males sex hormones) leads to decreased levels of PSA, and death
of prostate cancer cells. |
 Dietary
fat appears to play a role in prostate cancer but studies are conflicting. If
dietary fat is a risk factor, it appears that saturated fat from animal origins
is a greater risk factor than unsaturated fat from vegetable origin. The
mechanism by which fat may be involved in prostate cancer has been hypothesized.
First, dietary fat increases serum levels of male sex hormones (androgens). Some
studies indicate that omega 3 oils (fish oil, flaxseed oil) may actually prevent
prostate cancer..
Finally, many studies have found that there is a relationship between the amount
of fat eaten by the mother during pregnancy and the later development of
prostate cancer in her male offspring.
 Previous
articles have outlined the benefits of eating a Mediterranean
style diet,
consisting of plenty of fresh fruits and vegetables, fish, and olive oil. This
type of diet has benefits for cardiovascular health, and appears to be advisable
for prevention of cancers of all types.
Finally, there is
some evidence that exposure to pesticides and heavy metals may be a risk factor
for prostate cancer. Specifically there may be a relationship between dioxin (a
contaminant of herbicides) and prostate cancer. Likewise, the metal cadmium
found in NiCad batteries is suspect. Workers in plants that manufacture or
recycle these batteries should take extreme precautions to prevent exposure.
