Sauerkraut can be an important part of diets designed for healing cancer. Sauerkraut is a German word that simply means sour white cabbage. Lacto-fermented cabbage has a long history of providing benefits for many different health conditions, and now it is proving to be beneficial for cancer. Cabbage, by itself, offers a number of health benefits, but the fermentation process increases the bioavailability of nutrients rendering sauerkraut even more nutritious than the original cabbage.1
In 2005, a team of researchers from Poland and the United states observed a substantially higher rate of breast cancer among Polish women who immigrated to the United States. They compared Polish women who were living in and near Chicago and Detroit with women who were still living in Poland. They observed that the rate of breast cancer was three times higher for the Polish immigrants. They evaluated various factors and concluded that the consumption of lacto-fermented sauerkraut was a possible factor in the different cancer rates. Women in Poland ate an average of 30 pounds of raw sauerkraut each year, while the Polish women in the US were eating approximately 10 pounds per year.2
What are the qualities of sauerkraut that would make it a super food for cancer prevention, and to be included as a part of diets designed to treat cancer? Let’s take a look at some of the science.
Sauerkraut contains high levels of glucosinolates. These compounds have been shown to have anti-cancer activity in laboratory research.
“The observed pattern of risk reduction indicates that the breakdown products of glucosinolates in cabbage may affect both the initiation phase of carcinogenesis -by decreasing the amount of DNA damage and cell mutation -and the promotion phase, by blocking the processes that inhibit programmed cell death and stimulate unregulated cell growth,” said Dorothy Rybaczyk-Pathak from the University of New Mexico.3
Pathak, along with colleagues from Michigan State University and the National Food and Nutrition Institute of Warsaw, Poland, found that “Women who ate at least three servings a week of raw- or short-cooked cabbage and sauerkraut had a significantly reduced breast cancer risk compared with those who only ate one serving per week.” They discussed these findings at the American Association for Cancer Research’s Frontiers in Cancer Prevention Research meeting in Baltimore, Maryland in 2005.4
A study published in 2012 in the journal Nutrition Cancer showed that consumption of cabbage and sauerkraut is connected with significant reduction of breast cancer incidences. Estrogens are considered a major breast cancer risk factor and their metabolism by P450 enzymes substantially contributes to carcinogenic activity.
The aim of this study was to investigate the effect of cabbage and sauerkraut juices on key enzymes involved with estrogen metabolism in laboratory cell tissue. The 2012 study conducted by Hanna Szaefer, Et Al. showed that their research “supported the epidemiological observations and partly explain the mechanism of the chemopreventive activity of white cabbage products.” In other words their research supported the observation that the consumption of sauerkraut was a beneficial food for the prevention of breast cancer in women.5,6
The preceding studies do not show that sauerkraut by itself is a cure for cancer. They do show that eating sauerkraut has various health benefits, among which is the prevention of cancer, and that eating raw sauerkraut can be part of a natural treatment program for certain cancers.
Raw Fermented Cabbage is Traditional Healthy Sauerkraut
Not all sauerkraut has health benefits. In order for sauerkraut to have a preventative effect for cancer, it needs to be raw. Raw naturally fermented sauerkraut contains lactic acid and the living probiotic microorganisms that are the agents of fermentation. Canned sauerkraut, pasteurized sauerkraut, or fully cooked sauerkraut does not have this healing power, because the microorganisms have been killed by extended exposure to high heat. Cooking and pasteurization also damages other cancer preventative properties.
Naturally fermented cabbage is normally made from finely shredded cabbage and salt. The salt preserves the cabbage for a few days while the probiotic bacteria begin to grow. These probiotic bacteria are highly beneficial to human digestion and are the mechanism that turns cabbage into a super nutritious food. Naturally fermented sauerkraut does not contain vinegar. The sour taste comes directly from the process of fermentation. The sugar in cabbage is converted into lactic acid, which gives the cabbage its characteristic sour flavor. The lactic acid also preserves the cabbage and prevents it from rotting. Properly fermented sauerkraut can be kept for years without refrigeration as long as it is stored at a cool temperature.
