Consuming fruits and vegetables lowers risk of developing NHL

19.10.2004


While the struggle continues to encourage Americans to consume more fruits and vegetables, science has now suggested its value in preventing yet another form of cancer. According to a study presented today at the American Association for Cancer Research Third Annual International Conference on Frontiers in Cancer Prevention Research, vegetables, fruits and antioxidant vitamins may reduce the risk of non-Hodgkin lymphoma (NHL), a form of cancer of the lymphoid tissue.



The results of this study, conducted by the National Cancer Institute and four academic centers in Iowa, Seattle, Los Angeles and Detroit, show that individuals who consumed three or more servings of vegetables per day (not including potatoes) had a 40 percent lower risk of developing NHL compared to people who ate less than one serving per day.

The findings were particularly strong for one or more servings per day of green leafy vegetables and one half or more servings per day of vegetables from the broccoli and cabbage family (including cauliflower and Brussels sprouts).


Lower risks were also found, although not significantly, with higher intakes of whole fruits (excluding juices), yellow/orange/red vegetables and processed tomato products such as tomato sauce and tomato juice. For specific nutrients, higher intakes of both selenium and zinc were also associated with lower risk of NHL. The researchers found no strong link to increased intakes of the individual vitamins A, C, or E, or individual carotenoids or retinol.

The researchers investigated this relationship based on the results of a dietary questionnaire administered to more than 450 men and women with NHL between the ages of 20 to 74 years, who were identified from four large cancer registries across the country. These study participants were matched to approximately 400 individuals without cancer who were similar in age, sex, race and lived in the same geographical region.

"This type of study design has some limitations because we are asking people who already developed cancer to remember how often they ate fruits and vegetables in the year prior to cancer diagnosis," said Dr. Linda Kelemen, RD, ScD, of Mayo Clinic College of Medicine, and lead investigator of the study. "However, even after taking into account other possible risk factors like smoking, our results are consistent to those of studies where diet was assessed in healthy people who were followed forward in time to see if they develop cancer.

A novel finding was the lower risk observed with selenium and zinc, and confirmation of this observation by other researchers will be an important area of future research."

Although specific links between individual antioxidants such as vitamins C and E were not found with NHL in this study, vegetables and fruits contain many other nutrients that may explain the association with NHL. "Dietary modifications such as eating more vegetables and fruits are within the public’s grasp to lower their risk of cancer and other diseases. We hope that these findings, in conjunction with continued research and reporting, will help to favorably change the public’s eating behavior," said Dr. Kelemen.

According to the American Cancer Society, there will be more than 54,000 new cases of NHL in this country in 2004, and more than 19,000 people will die of the disease. Although some types of NHL are among the most common childhood cancers, more than 9 out of 10 cases occur in adults.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
