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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
