Vegetables and fruit has long been known to be able to reduce the risk of the emergence of certain cancers. Based on previous research, the American Cancer Society recommends that we consume five fruits and vegetables every day.
In the initial study, researchers from Ohio State University to find, let us protect the black from esophagus cancer by oksidatif reduce the stress produced by Barret esophagus, a pre-cancerous condition called the disease gastroesopagus refluks. Esophagus is a long tunnel connecting the esophagus with the stomach. Refluks disease causes stomach acid continues to soar to the top of the esophagus. And cause heat in the mouth.
"Especially in patients with Barret, refluks in the stomach and bile acid contribute to damage oksidatif. So, our hypothetical is that the foods that contain materials such as protective antioxidants, vitamins, minerals and other fitokimia may restoration balance oksidatif," said Laura Kresty , The main researcher.
People with the disease Esophagus Barret generally 30 to 40 times the risk of suffering usually intended esophagus cancer. Life expectancy figures up to five years, only 15 percent.
The research team is giving up to 32 black and 45 grams give each day during the six months to 20 patients with esophagus Barret. They analyze the changes in the blood, urine, and the network before, during, and after treatment and find a marker of stress rate oksidatif lower in both the urine sample and the network.
In previous research, given the black engender reduce the risk of mouth cancer, esophagus and colon. Dietitian, Wendy Demark-Wahnefried, behavioral science professors at the MD Anderson Cancer Center at the University of Massachusetts, Huoston, said that he felt more suitable advise people to consume Barret give black. "This will not hurt," said Wendy.
Meanwhile, research conducted at the Roswell Park Cancer Institute in Buffalo, New York, the United States found that broccoli and some fresh vegetables can be used to fight bladder cancer.
By using mice, the team by Dr. Yuesheng Zhang, professors cancer experts this demonstrates that the broccoli extract can reduce the emergence of bladder cancer to 70 percent.
"Our latest research shows that the broccoli extract can hamper the development of bladder cancer. We do not know whether the extracts, the same can prevent cancer when the bladder is growing," said Zhang who also revealed that the content of sulforaphane in broccoli is capable of preventing cancer.
"Next we plan to examine the broccoli extract to fight cancer in humans," said Zhang.
The second team in the same institute found that those who consume three or more portions of fresh raw vegetables every month to reduce the risk of bladder cancer affected as much as 40 percent. Fresh vegetables is broccoli, among others, kobis, cabbage and flowers.
This team is analyzing the habits of diet on 275 people suffering from bladder cancer early stage and 825 healthy people. The researchers specifically asked this how many people consume these vegetables raw and cooked before consumption, which they diagnose the disease and whether they smoke.
This analysis shows that more raw and fresh vegetables consumed, the lower the risk of people suffering from bladder cancer. In comparison to the smoker and that they only consume raw vegetables less than three portions per day, they are not a smoker and consume three portions of raw vegetables every day, 73 percent lower risk suffering from bladder cancer.
"In our research, found consumption of fresh vegetables and raw reduce the risk of bladder cancer in the light and heavy smoker," said Li pliers, the chief researcher. The researchers emphasize that this benefit comes from raw vegetables and fresh.
"It also confirms that there are many components in the multiplicity of fruits and vegetables that benefit lower risk of cancer. Research such as this help us understand the effects of nutrition specific to certain types of cancer," said Colleen Doyle, Director of Gizi and Physical Activity at the American Cancer Society.
"Cooking vegetables as soon as possible or, if possible Consume fresh vegetables every day at least five portions of five types of color. Food-food contains antioxidants and fitokimia. Cancer certainly reluctant at your body," said Doyle. Healthy Lifestyler.
