The benefits of fruits and vegetables in staving off cancer exist, but they're not as strong as previously believed, a new study reports.

Eating an additional 200 grams a day of fruits and vegetables (about two servings) resulted in only a 3 percent reduction of cancer risk, which was described as "very weak," according to the study published online in the Journal of the National Cancer Institute.

"This doesn't mean fruits and vegetables aren't important," said lead author Dr. Paolo Boffetta, the deputy director at the Tisch Cancer Institute at the Mount Sinai School of Medicine. "They aren't the only factor. There is no one factor."

The World Health Organization, Centers for Disease Control and Prevention and the American Cancer Society all encourage people to maintain a healthy lifestyle and eat five servings of produce a day for cancer protecting benefits.

The U.S. government's food pyramid recommends 1.5 to 2 cups of fruits a day and 2.5 to 3 cups of vegetables for adults

Scientists think fruits and vegetables have anti-cancer compounds, affecting enzymes, immune system and hormone levels.

From 1992 to 2000, Boffetta and the 51 co-authors obtained self-reported dietary and lifestyle habits of 478,478 people from the European Prospective Investigation into Cancer and Nutrition. The participants answered questions about their medical histories, physical activities, tobacco and alcohol use, and habitual diet.

They lived in 10 Western European countries and ate varying diets. About eight years later, a follow-up revealed that more than 30,000 participants had cancer -- the incidence rate was about 7 per 1,000.

Researchers raised the prospect that people who ate more fruits and vegetables could have lower cancer risks because they had generally healthier lifestyles, "such as lower intake of alcohol, never smoking, short duration of tobacco, and higher level of physical activity." These could've been factors rather than just fruit and vegetable intake.

Previous studies have touted the benefits of produce, with findings of 20 to 30 percent reduced cancer rates. The latest finding from the European study was low in comparison.

"Diet is a complex pattern and lifestyle," Boffetta said. "Cancer is complex disease. It's unlikely that one thing will explain the other."

The study does not contradict existing American Cancer Society guidelines about eating five servings a day to reduce cancer risk, said Dr. Michael Thun, the organization's vice president emeritus of epidemiology. It reaffirmed existing notions that higher intake lowered cancer risk, he said.

"In my view, there is a good body of evidence that fruit and vegetables do matter for cancer -- it certainly matters for heart disease," Thun said. "It's not as strong as initial studies suggested."

Decades of research have shown that eating processed red meat increases risk of cancers in the digestive tract and that obesity is associated with colorectal and breast cancer. But "the story on vegetables and fruits has been harder to nail down," Thun said.

Dr. Christine Gerbstadt, a spokeswoman for the American Dietetic Association, warned against slacking off on daily fruit and vegetable intake because of this study.

She pointed out eating fruits and vegetables has benefits beyond the cancer realm.

"It does help with lowering weight and blood pressure, lowering diabetes risk or lowering blood sugar. Those are all health benefits that increase lifespan significantly."

They also provide soluble and insoluble fiber, minerals, high nutrients and low calories, she added.

The Scientific is not really settle down isn't it, a while back i was reading New England Journal of Medicine. most of these researchers Dr cameout and tell people that if you eat everyday Chocolate it will make you fat and high Cholestrol level. and a year later, some of the researchers from John Hopkin Medical center comeout and tell people that if you eat chocolate everyday it'll help your heart. this is very funny i think.. all these Dr has too much time on their hand or what ??... and same thing as the story above, Fruits and Vegetable can't cure a cancer prevention...

There is only one answer to that brother Speakout. Vested interest!
What is being promoted depends on who can give the bigger $$$ among the most
popular advocates. Notice who starts such claims. For example, when it was "discovered" that coffee has lots of anti-oxidants during the time coffee is threatened by the campaign for "healthy lifestyle" (coffee is proven a blood vessel constrictor and too much consumption can weaken the vessels or cause hypertension). Who made the discovery? Their own coffee company-funded scientists. Who spent large amount of $$$ to "spread the good news?" The coffee industry giants themselves.

Moral of the story... be an educated/ smart consumer.

Im sure there is a sequel to that. Maybe a new anti-cancer drug was discovered and people's preference to natural methods is being diverted.
