Kohlrabi is a variety of cabbage. It is a veritable weapon against cancer, cardiovascular disease and neurodegenerative disorders. As a nutritionist likes to say, “Kohlrabi deserves to be in every plate of people who want to become or stay healthy.”
High in fiber, this nutritious vegetable facilitates intestinal transit. Among other health elements it contains included Sulforaphane, which has a destructive effect against H. Pylori bacteria present in the stomach and can lead to ulcers and cancers. Sulforaphane, along with indoles, is also implicated in the destruction of cancerous cells in the entire body.
Health Benefits of Kohlrabi
Several epidemiological studies have shown high consumption of vegetables and fruit reduces the risk of cardiovascular disease, some cancers, and other chronic medical conditions. It is believed the presence of antioxidants in fruits and vegetables may play a role in this protection. But some plants are more powerful in fighting cancer than others; kohlrabi is one of them.
Kohlrabi and Cancer Prevention
Several studies have shown that regular consumption of kohlrabi, as well as other cruciferous vegetables (cabbage, cauliflower, broccoli, Brussels sprouts…), may prevent certain cancers, such as lung, ovary and kidney. Although recent researches report that vegetables from the cruciferous family have preventive effect on almost all cancers, current epidemiological evidence suggests they are mainly effective in decreasing the risk of malignant tumor in the lung, prostate, breast, and the organs of the digestive system.
Kohlrabi and Cancers of Prostate and Breast
In vitro studies and in animals, it is shown that two active compounds in kohlrabi, the sulforaphane and indole-3-carbinol, could prevent tumor formation, decrease the growth of cancer cells and promote their self-destruction. Although these studies were mostly focus on cancer associated with hormone system (breast cancer, prostate cancer), other results in animals also show a beneficial effect against cervical cancer.
In addition, it was observed that sulforaphane in Kohlrabi has the ability to kill or reduce overgrowth of H. pylori, a bacterium which can infect and cause stomach ulcer and cancer in humans. Further research is needed before confirming these results in humans. Considering the currently available medical data, it appears that frequent consumption of vegetables from the cruciferous family reduces the risk of metastasis in people who were diagnosed with malignant tumor.
Irritable bowel syndrome. Some people with irritable bowel syndrome may experience intolerance to crucifers, such as kohlrabi. It is therefore important to limit the intake of the vegetable in case of abdominal pain, bloating, and/or diarrhea. When the symptoms are mild or insignificant you can gradually reintegrate these foods, based on your body tolerance.
Interaction between cruciferous and certain medications. Indoles, compounds found naturally in cruciferous vegetables may reduce in particular the action of some analgesics such as products containing acetaminophen (Tylenol®, Atasol®, Tempra®) and other drugs like BENYLIN®, Contac®, and Robaxacet®.
