A 50-year-old Hong Kong bank manager who had three precancerous colon polyps removed managed to achieve zero recurrence and a “pink, healthy” colon after a dramatic dietary overhaul centered on one humble vegetable—cabbage.
In a compelling case shared by Taiwanese nephrologist Dr. Hung Yung-hsiang on the health program “Healthy Life,” a patient’s story is offering hope to the thousands of Hongkongers at risk of colorectal cancer—the city’s second deadliest cancer. The man, a high-pressure bank executive in his 50s, had long suffered from poor eating habits, hypertension, chronic constipation, and bad breath. His world turned upside down during a routine health check when doctors discovered three adenomatous polyps, a type of precancerous lesion that, if left untreated, can rapidly progress into colorectal cancer.
A Simple Prescription: Eat More Cabbage
After surgical removal of the polyps, the patient was anxious about recurrence and asked Dr. Hung about supplements. Instead, the doctor advised a fundamental shift in diet: drastically reduce red meat, switch to white meat, and consume large quantities of the “cabbage family” —including Napa cabbage, Chinese black leaf cabbage, and baby cabbage.
The man followed this advice diligently for three full years. When he returned for a follow-up colonoscopy, the examining colorectal specialist was astonished. Not only was there zero polyp recurrence, but the patient’s colon appeared “pink and tender, beautifully clean without any growths.” His long-standing hypertension, constipation, and bad breath had also completely resolved.
Why Cabbage Is Called the “King of 100 Vegetables”
Dr. Hung explained that cabbage, often dubbed the “king of vegetables” in nutritional circles, is listed by the American Cancer Society as one of the top 30 cancer-preventive foods worldwide. Its power lies in three key compounds: isothiocyanates, vitamin C, and dietary fiber.
Gastroenterologist Dr. Wang Weidi, also appearing on the program, added that Napa cabbage is rich in quercetin, selenium, and zinc—trace elements and phytochemicals that work together to deliver potent antioxidant effects. These nutrients help eliminate harmful free radicals linked to aging and cancer.
8 Health Benefits of the Cabbage Family
According to the physicians, regular consumption of cabbage can provide:
- Cancer prevention – isothiocyanates inhibit tumor growth
- Detoxification – high vitamin C and water content help flush heavy metals
- Constipation relief – fiber promotes bowel movement
- Immune system boost – vitamins and minerals strengthen defenses
- Heart protection – lowers blood pressure and cholesterol
- Anti-aging – antioxidants combat oxidative stress
- Satiety support – low-calorie, high-volume aid weight management
- Bone and dental health – calcium and vitamin K strengthen teeth and bones
A Broader Lesson for Hong Kong
With colorectal cancer claiming over 2,000 lives annually in Hong Kong, this case underscores the power of prevention. While polyps are a major warning sign, experts stress that early detection through regular screening combined with aggressive dietary intervention can reverse the trajectory.
Dr. Hung emphasizes that no single food is a miracle cure, but cabbage is an affordable, accessible, and scientifically supported addition to any anti-cancer diet. The patient’s transformation from a stressed, meat-heavy lifestyle to a vegetable-centered one demonstrates that even high-risk individuals can regain control of their gut health.
Actionable Takeaway: For those concerned about colon health, experts recommend:
- Schedule regular colonoscopies after age 50—or earlier if you have risk factors
- Cut red meat intake to no more than two portions per week
- Incorporate cabbage-family vegetables into daily meals (soups, stir-fries, salads)
- Stay hydrated and maintain a high-fiber diet
