Tomatoes Can Punch Out Prostate Cancer

Tomatoes Can Punch Out Prostate Cancer
Prostate cancer remains one of the most common cancers in men and causes the death of nearly 30,000 men each year. The cause of prostate cancer is unknown but we do know that having a family member with prostate cancer and African American men have a higher incidence of prostate cancer which leads me to believe that there is a genetic or hereditary basis for prostate cancer.

A recent study from the Journal of National Cancer Institute has pointed out that increased consumption of lycopenes, which are found in tomatoes, tomato-based products, pink grapefruit, and watermelons appear to decrease the risk of prostate cancer.

The study suggests that increasing the consumption of a diet rick in lycopene-containing foods reduces the aggressive potential of prostate cancer. The study showed that a high in take of tomato or tomato-based products was associated with a 10%-20% decrease in prostate cancer risk and those men who had high blood levels of lycopenes had a 25% decrease risk of prostate cancer.

For those men who do not like tomatoes, you can take a supplement of lycopene, 20-25mg per day.

Bottom Line: No one knows for certain why lycopenes decreases the risk of prostate cancer. But as my wise Jewish mother would say, “It may not help, but it voidn’t hoit.”

Prevent Prostate Cancer-Try a Tomato

June 22, 2011

That wonderful, tasty fruit\vegetable just may be what the doctor ordered for prostate cancer prevention.  The primary nutrient behind tomatoes’ healing power is lycopene, a powerful antioxidant that works by neutralizing free radicals which can be a cause of cellular damage leading to the development of prostate cells becoming cancerous.  Eating foods that are high in lycopenes protects against a wide range of cancers, from prostate cancer to lung and breast cancer.

There’s more good news.  Tomatoes can also help prevent heart attacks by lowering cholesterol levels.  Lycopenes also increase bone mineral density and may be protective against hip fractures.  Also, lycopenes can help prevent type-2 diabetes.

It is estimated that three or more servings a week of tomatoes are adequate for the purpose of prostate cancer prevention.

Bottom Line:  No one is certain about what causes prostate cancer.  However, we do know that dietary abuses are partly responsible for the cause of prostate cancer.  We also know that certain supplements including lycopenes can be helpful in preventing prostate cancer.  So in addition to your apple to keep the doctor away, throw in a few tomatoes.

An Apple a Day May Keep the Doctor Away-and Proscar or Avodart May Keep Prostate Cancer at Bay

Prostate cancer is the most common non-skin malignancy in men and is responsible for more deaths than any other cancer, except for lung cancer. However, microscopic evidence of prostate cancer is found at autopsy in many if not most men. The American Cancer Society (ACS) estimated that about 218,890 new cases of prostate cancer were diagnosed in the United States during 2007. About 1 man in 6 will be diagnosed with prostate cancer during his lifetime, but only 1 man in 34 will die of it. More than 1.8 million men in the United States are survivors of prostate cancer.

There is some evidence that links exercise to better prostate health.  Exercise improves overall physical and mental health, so most medical professionals recommend at least a half an hour of exercise per week. Some studies indicate that regular exercise increases oxygen flow to the soft tissues of the body and helps to control glucose levels in the bloodstream. High levels of glucose may help fuel prostate cancer cells.

A healthy prostate diet is worth considering. High-fat and low-fiber diets and obesity seem to contribute to a higher risk of prostate cancer.  Some researchers believe that cancerous prostate cells can feed on fat, especially fats found in red meat and dairy products. Omega 3 fatty acids, found in fish, soy, and flaxseed is known as the “heart-healthy” fats. Now we believe that the Omega-3 fatty acids are prostate healthy as well. Countries, like China and Japan, whose diets are based on fish proteins rather than red meat have much lower rates of prostate cancer. Soy products include tofu, soymilk, soy creamers, soy yogurts, soy ice creams, and tofu burgers.  Red grapes, grape juice, green teas, and red wine contain anti-oxidants that can neutralize cancer-causing agents within the body. Lycopene found in tomatoes, and beta-carotene may be beneficial in helping to protect the body from the risk of prostate cancer.  Eating a variety of fresh fruits and vegetables may help boost the body’s cancer-fighting abilities.

Supplements such as vitamin E and selenium have been linked to a drastically decreased risk of prostate cancer. Studies of vitamin E and selenium seem to benefit those who were deficient in either Vitamin E or selenium, or who were ex-smokers. Studies have also noted that a daily regimen of aspirin or ibuprofen lowers risks of prostate cancer.

A few years ago a long-term study using the 5-alpha reductase inhibitor, Proscar or Avodart, lowers the risk of prostate cancer.  This study as well as others has shown a 25% reduction in prostate cancer.  However, the risk of developing a high-grade cancer or a more aggressive cancer was greater in those men taking finasteride as compared to a placebo or sugar pill.

So what is a man to do?  If you are at risk for prostate cancer, i.e., you have a relative such as a father, brother, uncle with prostate cancer, are Afro-American, or are obese and consume a high fat and meat diet, then you should talk to your doctor about prostate cancer prevention using one of the agents like Proscar or Avodart.  For the rest of the men: get an annual digital rectal exam and a PSA blood test once a year after age 50 or after age 40 if you are at high risk for prostate cancer.

Bottom Line: Knowledge is your best weapon for good prostate health and avoiding prostate cancer. Some lifestyles, eating habits, and dietary supplements are thought to lead to lower levels of prostate cancer, as well as other cancers. Nobody can guarantee prostate cancer prevention through behavior, diet, treatment, or medicine, but there are things you can do to improve your odds.
