Tomato-Broccoli Combo May Protect Against Prostate Cancer

Broccoli and tomato – two vegetables known to help fight cancer – are more effective against prostate cancer if they’re eaten together as part of a daily diet than if they’re eaten alone, a new study with rats suggests.

University of Illinois researchers fed a diet containing 10 percent broccoli powder and 10 percent tomato powder to a group of rats that had been implanted with prostate cancer cells. Other groups of rats received either tomato powder or broccoli powder alone; a supplemental dose of lycopene (the red pigment in tomatoes believed to be an anti-cancer agent); or finasteride, a drug prescribed for men with enlarged prostates. Another group of rats was castrated.

After 22 weeks, the researchers found that the combined tomato/broccoli diet was the most effective at prostate tumor reduction. Of the other treatments, castration was the only one that came close to being as effective.

“When tomatoes and broccoli are eaten together, we see an additive effect. We think it’s because different bioactive compounds in each food work on different anti-cancer pathways,” study co-author John Erdman, a professor of food science and human nutrition, said in a prepared statement.

“Older men with slow-growing prostate cancer who have chosen watchful waiting over chemotherapy and radiation should seriously consider altering their diets to included more tomatoes and broccoli,” added study co-author and doctoral candidate Kirstie Canene-Adams.

“To get these effects, men should consume daily 1.4 cups of raw broccoli and 2.5 cups of fresh tomato, or 1 cup of tomato sauce, or 1/2 cup of tomato paste. I think it’s very doable for a man to eat a cup and a half of broccoli per day or to put broccoli on a pizza with 1/2 cup of tomato paste,” Canene-Adams said.

Green Tea Supplement Prevents Prostate Cancer in High-Risk Men

Green Tea Supplement Prevents Prostate Cancer in High-Risk Men

A supplement containing antioxidants from green tea was 90 percent effective in preventing prostate cancer in men at high risk for the disease.

There are many benefits to drinking green tea, but you’ll need to drink 12 cups a day to get the amount of catechins consumed in the study.

That’s the conclusion of an Italian study that found after a year of taking green tea catechins, only one man in a group of 32 who were at higher risk of prostate cancer actually developed the disease, while nine men in a group of 30 high-risk men who took a placebo developed prostate cancer.

‘To our knowledge, this is the first study showing that green tea catechins (GTC) have potent chemoprevention activity for human prostate cancer,’ said study author Saverio Bettuzzi, an associate professor of biochemistry in the School of Medicine at the University of Parma in Italy.

Findings from the study were presented April 20 at the American Association for Cancer Research annual meeting, in Anaheim, Calif.

Other than skin cancer, prostate cancer is the most common cancer affecting men. More than 230,000 American men are diagnosed with this disease each year, according to the American Cancer Society. Since many prostate cancers are found in their early stages, about 99 percent of those diagnosed can expect to live at least five years, while up to 92 percent survive for at least 10 years after their diagnosis. However, prostate cancer can be deadly. The disease claims the lives of more than 30,000 men in the United States annually, making it the second largest cancer killer in men.

Bettuzzi explained that while other studies, including his own previous work, had shown that green tea could inhibit prostate cancer cell growth in laboratory models, the researchers wanted to know if it would work in humans.

They recruited 62 men at high risk of developing prostate cancer because they already had precancerous lesions, which often turn into cancer within a year.

The men were between the ages of 45 and 75. The researchers excluded vegetarians because they may already have a lower risk of developing prostate cancer, men who already consumed green tea, and men taking antioxidant supplements or hormone therapy.

Thirty two of the men were asked to take a 200-milligram pill containing green tea catechins three times daily for a year; the other 30 men were given a placebo.

Biopsies were conducted at six months, and then again a year later.

Remarkably, only one man in the treatment group was diagnosed with prostate cancer, while nine men in the control group developed the disease.

‘A projection of our data suggests that up to 90 percent of chemoprevention efficacy could be obtained by GTC administration in men prone to developing prostate cancer such as the elderly, African-Americans and those with a family history of prostate cancer,’ Bettuzzi said.

He said to consume an amount equivalent to that used in the study, you would have to drink 12 to 15 cups of tea daily, and that while supplements are commercially available, their quality cannot be assured and they may contain caffeine, or more alarmingly, pesticides or other contaminants.

Bettuzzi also said his findings would be confirmed in a larger study.
