Sauerkraut contains anticancer compound

17.10.2002


Baseball fans might want to add a little more sauerkraut to their hot dogs: Researchers have identified compounds in the tangy topping, made from fermented cabbage, that may fight cancer. Their study will appear in the Oct. 23 print issue of the Journal of Agricultural and Food Chemistry, a peer-reviewed journal of the American Chemical Society, the world’s largest scientific society.



The researchers found that the process of fermenting cabbage produces isothiocyanates, a class of compounds that have been identified in previous studies as potential cancer-fighting agents. In animal studies, the compounds appear to prevent the growth of cancer, particularly in the breast, colon, lung and liver, they say. No one knows yet whether the compounds, which are not found in raw cabbage, have a similar effect in humans. Further studies are needed, they add.

"We are finding that fermented cabbage could be healthier than raw or cooked cabbage, especially for fighting cancer," says Eeva-Liisa Ryhanen, Ph.D., research manager of MTT Agrifood Research Finland, located in Jokioinen, Finland. "We are now working on ways of optimizing the fermentation process to make it even healthier so that consumers will eat more [sauerkraut]."


In the current study, the researchers analyzed a variety of biologically active compounds in sauerkraut. Their samples were derived from white cabbage that was fermented.

Although raw cabbage is normally rich in a compound called glucosinolate, the researchers found that during the fermentation process enzymes are released that completely decompose the compound into several breakdown products. The majority of these products are cancer-fighting isothiocyanates.

Evidence for sauerkraut’s anticancer effect is growing. Previous epidemiological studies have reported that Polish women who move to the United States have a higher incidence of breast cancer than those who remain in Poland, a statistic that some scientists attribute to a higher consumption of cabbage among the Polish women compared to their American counterparts.

At least one study found evidence that compounds in sauerkraut could inhibit estrogen, a hormone that can trigger the spread of breast cancer. The specific compounds have not been identified, however.

Currently, the researchers are investigating the effect of different starter cultures on the breakdown of glucosinolate. They hope the research may lead to sauerkraut with a greater abundance of healthy compounds, boosting its status as a functional (nutritious) food.

Besides anticancer compounds, the fermentation process also produces other healthy compounds not found in raw cabbage. These include organic acids such as lactic acid, which makes cabbage easier to digest. Although some loss in nutrients may occur during fermentation, sauerkraut is still a good source for vitamin C, certain minerals and dietary fiber, the researchers say.

Their work also adds to a growing number of studies demonstrating that similar cruciferous vegetables (including broccoli, cauliflower and Brussels sprouts) contain anticancer compounds.

Sauerkraut is a low-calorie, low-fat food that is second only to mustard as this country’s favorite hot dog topping. Americans annually consume an estimated 387 million pounds of sauerkraut, or about 1.5 pounds per person yearly, according to Pickle Packers International, Inc., a trade association for the pickled vegetable industry.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
