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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
