Eating fruits and vegetables associated with reduction in cardiovascular disease, but not cancer

03.11.2004


Increased fruit and vegetable consumption is associated with a decreased risk of cardiovascular disease but not cancer, according to a new study in the November 3 issue of the Journal of the National Cancer Institute.



Eating five or more servings of fruits and vegetables daily has been recommended to reduce a person’s risk of cardiovascular disease and cancer, the leading causes of death in the United States. Studies have evaluated the association of fruit and vegetable consumption with the reduction of risk of specific diseases, but their overall associations with cardiovascular disease and cancer have rarely been evaluated in large cohort studies.

To evaluate the relationship between fruit and vegetable consumption and the incidence of cardiovascular disease and cancer, Walter C. Willett, M.D., of the Harvard School of Public Health in Boston, and colleagues analyzed data from more than 100,000 participants in two large cohort studies, the Nurses’ Health Study and the Health Professionals’ Follow-up Study.


The researchers found an inverse association between total fruit and vegetable intake and the risk of cardiovascular disease but no relationship with cancer incidence. In an analysis of different groups of fruits and vegetables, consumption of green leafy vegetables showed the strongest inverse association with both cardiovascular disease and major chronic disease--that is, cancer and cardiovascular disease combined.

"Consumption of five or more servings of fruits and vegetables per day has been recommended in the National 5 A Day for Better Health Program for cancer prevention, but the protective effect of fruit and vegetable intake may have been overstated," the authors write. However, "our findings for cardiovascular disease still support the recommendations of the American Heart Association of consuming at least five servings of fruits and vegetables per day."

In an editorial, Arthur Schatzkin, M.D., Dr.P.H., and Victor Kipnis, Ph.D., of the National Cancer Institute, discuss the possibility that substantial errors in measuring diet as well as other confounding factors in the study may have distorted true associations between fruit and vegetable intake and cancer, and they suggest several ways researchers might deal with these problems. They write, "the evidence is simply inadequate at this time to determine whether fruit and vegetable intake confers modest protection against cancer. Researchers should recognize this uncertainty in nutrition and cancer epidemiology and do what it takes to move ahead, especially when it comes to improving exposure assessment in observational studies."

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...

Im Focus: Autoimmune Reaction Successfully Halted in Early Stage Islet Autoimmunity

Scientists at Helmholtz Zentrum München have discovered a mechanism that amplifies the autoimmune reaction in an early stage of pancreatic islet autoimmunity prior to the progression to clinical type 1 diabetes. If the researchers blocked the corresponding molecules, the immune system was significantly less active. The study was conducted under the auspices of the German Center for Diabetes Research (DZD) and was published in the journal ‘Science Translational Medicine’.

Type 1 diabetes is the most common metabolic disease in childhood and adolescence. In this disease, the body's own immune system attacks and destroys the...
