Among cruciferous vegetables, which include cauliflower, cabbage, and Brussel sprouts, broccoli seems to be the most researched for its antioxidant, cancer preventative, and anti-carcinogen qualities. A 2017 study at Penn State University was centered on how broccoli and cruciferous vegetables may affect gut health, including permeability or leaky gut and other gut disturbances. Leaky gut or gut permeability has been brought to the forefront of medical concern since it has been determined to be a source of many other maladies. Two major reasons for this are: 1. It blocks nutrient absorption from the small intestines into the blood stream. 2. It allows toxins from ingested foods to escape the elimination process and enter the blood stream. These two concerns align with what Dr. Max Gerson, who created the Gerson Therapy for cancer and chronic disease, had proposed circa 1950 as the major causes of cancer and other non-infectious diseases, insufficient nutrition and overwhelming environmental toxicity.
