Eating raw sauerkraut prevents cancer

Anticancer Benefits of Sauerkraut(NaturalHealth365) Sauerkraut, that familiar hot dog condiment, may not have the beauty of garnet-colored raspberries or the sweet, refreshing flavor of tropical fruits. But the latest scientific research tells us that freshly-made organic sauerkraut is a true superfood that boosts the immune system, promotes intestinal health, and helps to prevent cancer in many ways.

How does sauerkraut prevent cancer?

Cabbage, the cruciferous vegetable from which sauerkraut is made, is already valued by natural food experts and nutritionists for its sky-high amounts of anticarcinogenic bioactive compounds. In fact, the glucosinolates in cabbage help to activate the body’s own antioxidants – which in turn fight the lipid oxidation and inflammation that can trigger cancer and heart disease.

Additionally, the process of lacto-fermentation involved in turning cabbage to sauerkraut produces beneficial bacteria and unleashes even more potent anti-inflammatory cancer-fighting substances – taking the health benefits to a whole new level and helping to ward off cancers of the prostate, bladder and breast.

Lactic fermentation helps to ward off cancer

According to author and natural health expert Sandor Ellix Katz, the process of lactic fermentation not only preserves the nutrients in food, but breaks them down so they are even more healthful and easily digested. But what, exactly, is lactic fermentation, and why is it beneficial?

Although the term sounds somewhat technical, it is actually the natural result of layering shredded cabbage in water with salt, then letting existing bacteria on the cabbage do the work. The end product – sauerkraut – contains more live probiotic cultures than yogurt.

One result of lacto-fermentation is to create large amounts of beneficial lactobacillus bacteria, which support friendly flora in the intestinal tract. Another is the release of isothiocyanate compounds, from existing glucosinolate; it is these isothiocyanates that have shown such pronounced anticarcinogenic effects in cell, laboratory and human studies.

Impressive science behind the benefits of sauerkraut

In an October 2002 article in Journal of Agricultural and Food Chemistry, researchers announced that they had isolated isothiocyanates in sauerkraut, and that these compounds had cancer-protective effects in animal studies. They added that clinical research would be required to determine if these effects extended to humans.

In the twelve years since the article was published, many studies on sauerkraut and sauerkraut juice show that it lowers cancer risk in humans – particularly for cancers of the breast and colon.

In a study published in 2011 in British Journal of Nutrition, researchers noted that the detoxifying enzymes in sauerkraut juice have an anticarcinogenic effect on kidney and liver cancer cells, and added that sauerkraut juice increased levels of glutathione-S-transferase – considered a chemoprotective agent.

Sauerkraut’s probiotic cultures attack cancer cells.

In a review published in 2006 in Journal of Applied Microbiology, researchers stated that lactic acid bacteria could prevent certain types of cancer – including colon and bladder cancer – and categorized the ways in which probiotic cultures help to torpedo cancer cell development.

Not only do probiotic cultures detoxify ingested carcinogens and stimulate the immune system, they also create an environment hostile to carcinogenic compounds. Specifically, they create organic compounds – including butyrate – that inhibit the growth of tumors and encourage the apoptosis, or programmed cell death, of cancer cells.

The authors theorized that probiotic cultures may also suppress bacteria responsible for turning procarcinogens to carcinogens, and added that lactobacillus could bind to mutagenic compounds in the intestine.

What is the best type of sauerkraut to prevent cancer?

Buy only sauerkraut that is freshly made, raw, unpasteurized and organic; your best bet is to look for it in the refrigerated aisle of local markets or farmers markets. Avoid canned sauerkraut, which offers far fewer nutrients and probiotic benefits.

Most experts recommend consuming at least 1 and ½ cups of sauerkraut 4 to 5 times a week; 2-cup servings, of course, are even healthier.

One cautionary note: raw sauerkraut produces raffinose, a trisaccharide that can’t be broken down in the intestine. Bloating and flatulence can result, but should subside as your body becomes accustomed to this healthful food.

Fresh lacto-fermented sauerkraut, packed with cancer-fighting compounds and antioxidants and high in healthful dietary fiber, is a superb nutritional choice.

    Sauerkraut is so easy to make. See Sandor Katz on YouTube to see how to make it. I like adding caraway seeds to mine.

  • techmans

    I think an explanation as to why canned ( it’s actually never in cans) sauerkraut would have fewer of the healthy benefits is in order since it does make no sense whatsoever.

    • Eat Living Foods

      Sauerkraut is found in cans in the grocery store. If you bought it that way, it is pasteurized / processed and does not have the living enzymes in it. If you buy it unpasteurized in the refrigerator section, or make it fresh, it has living enzymes in it. The fresher you eat your fruits and vegetables, the healthier they are for you. So it’s basically cooked vs not cooked. Lots of information on living enzymes and health benefits online.

      Sure it’s in cans, I have purchased it many many times, until now.

    • Eileen

      There is a good refrigerator/unpasteurized brand sold in some healthfood stores call Bubba.

    It’s easy to make your own sauerkraut. Just chop up cabbage, add salt 2tsp per pound, massage until water squeezes out, pack into jar(s), and leave for about 2 weeks, re-packing every day our two. When you like the flavor, stick it in the fridge and it will last for months.

    • annenNa999

      Thank you for giving us a recipe, it would have been great if one had been included in the article, but still good article.

      • Eileen

        You can also add a culture. It will ferment in about a week

      make sure to cover the top of the sauerkraut with the outer leafs of the cabbage… it tends to spoil if not. air=mold

    Aggressively treating gut dysbiosis with high quality pro-biotics, fermented vegetables like raw organic sauerkraut and kimchi (daily) along with eliminating all processed foods, glutenous grains and sugars – has been the key to treating my complex fistulizing crohns colitis.

    The so-called ‘treatments’ – anti-biotics and pharma drugs – they were giving me were making my condition worse and leading me quickly to an early grave.

    Because I took this into my own hands in this way my health has improved rapidly, I’ve been in 100% remission for months, and my gut is healing.

    I’m living proof.

    • jason amenta

      Hi vongoh, I would be interested to hear more about your story and what you are eating. Please email me… I have Crohn’s as well and have a fistula.

      • vongoh

        Hey jason – no problem, check your mail. You also might want to edit your email out of your post, spambots scan for that that and you may get unwanted spam …

    • Juanita Juniper

      yea, Vongoh!! I’m trying the raw sauerkraut today.

    • Mackenzie-Matthew Parent

      I am so happy when I see anyone who takes responsibility for their own health! When my Docter told me that my auto-immune disease was incurable and tried to make me dependent on prescription medication to function… that wasn’t good enough for me. It took a while but I am healed today and so glad I didn’t just listen. I think a turning point for me was when I found out that the simple mineral selenium greatly improved fibromayalgia… so I told my friend to eat 4 brazil nuts a day. She did and said it took all the pain away. My dad also was loosing his teeth, had gingivitis and high blood pressure. I told him to oil pull with coconut oil I also told him that high blood pressure was mostly from inflammation and that calcium is about one of the most anti-inflammatory things you can consume. He later found out that he had inflammation in his cardio vascular system. So he started oil pulling and went on a raw milk fast. Within 5 days his blood pressure went from 200 to 110 and he stopped loosing his teeth and healed his gingivitus. Natural healing has never disappointed me. 😛

        Thats great Mackenzie, glad to hear it – I posted that 2 years ago and my condition has continually improved since then. My flareups have grown less frequent *and* less severe consistently over time till now where I have had little to no symptoms at all since last February. I don’t miss sugar or processed foods one bit; in fact, if I ever do put anything with sugar or processed food in my mouth the taste disgusts me and I spit it out. After giving all of that up for a couple of years now, I can clearly taste that there is something inorganic and ‘off’ about it. Most of what corporations sell as ‘food’ is not fit for human or animal consumption and I can taste it.
