research suggests that phytochemicals in green tea may help prevent the
spread of prostate cancer. Since earlier research suggests that the
same natural plant substances might also help prevent the development
of prostate cancer, scientists say that more studies are needed on
green tea’s ability to fight this common cancer.
The best way to reduce your risk of prostate cancer, however, still lies in eating a mostly plant-based diet.
the new green-tea study, researchers observed that phytochemicals
called polyphenols attack growth factors and proteins, interrupting
processes that increase the size of tumors, thus preventing them from
spreading to other parts of the body.
study of green tea may help develop a treatment to prevent the dormant,
nonthreatening type of prostate cancer many men have late in life from
becoming aggressive and fatal.
presented at the most recent American Institute for Cancer Research
(AICR) conference on diet and cancer also show that green tea in mice
with an aggressive form of cancer can decrease the spread or metastasis
of prostate cancer to liver, bone and other sites.
Supplements may help
six cups of green tea per day would contain the equivalent amount of
polyphenols for humans to alter the balance of bodily processes and
substances that will help block the spread of cancer.
data presented at the AICR conference show that the phytochemicals in
green tea could inhibit the early stages of prostate cancer
example, the phytochemicals seem to increase the number of enzymes that
convert carcinogens to inactive, harmless forms. For now, however, many
questions remain about the amount and frequency of green tea necessary
to halt the formation of prostate cancer. Although black tea has shown
similar benefits to green tea, it appears to have lower levels of the
any case, it would be a mistake to rely on tea alone for prevention.
Studies suggest that there are a variety of nutritional influences on
prostate cancer risk. Vitamin E may offer some protection.
several important studies, the antioxidant mineral selenium also seems
protective. Almost all Americans get adequate amounts of selenium, but
these scientific studies used supplements, so the study participants
reached higher intake levels.
is unclear, however, whether men can protect themselves more from
prostate cancer by taking supplements, including multivitamins, with
selenium and eating more selenium-rich seafood, grains and vegetables.
If a person’s total selenium intake exceeds 400 mcg per day, nerve
damage and other side effects can occur.
Don't forget veggies
to more research presented at the AICR conference, two or more servings
per week of raw or cooked tomatoes lower the risk of prostate cancer
about 25 percent. The antioxidant phytochemical called lycopene is
often credited for the risk reduction, but other substances in tomatoes
may play a role.
protective phytochemical in cruciferous vegetables like broccoli was
mentioned at the AICR conference. This phytochemical,
indole-3-carbinol, seems to increase the body’s ability to block
carcinogens and halt the development of prostate cancer cells.
Phytochemicals in soy foods are also considered protective.
men want to lower their risk of prostate cancer, they should not
consider drinking green tea as a replacement for a healthy, plant-based
it is reasonable to replace less healthy drinks with tea. Although
black tea has health benefits, green tea’s higher levels of
phytochemicals called catechins may make it more potent.
combined with a mostly plant-based diet, the phytochemicals from tea
could have an even greater effect as all the plant substances interact
together to safeguard your health.
