The Cancer Myth vs. The Real Kidney Threat
A viral rumor online suggests that long-simmered hotpot broth can cause cancer. However, Dr. Yan Zonghai, Chief of Clinical Toxicology at Linkou Chang Gung Memorial Hospital, states there is no medical evidence to support this. Because hotpot temperatures remain around 100 degrees Celsius—unlike the extreme heat of grilling or deep-frying—it does not produce dangerous levels of carcinogenic nitrosamines. However, while cancer may not be the primary concern, your kidney health certainly is.
The Danger of Concentrated Sodium, Fats, and Purines
According to medical experts, after a hotpot boils for 30 minutes to over an hour, the broth becomes highly concentrated. During this process, the levels of sodium, saturated fats, and purines skyrocket. Drinking this dense soup is highly discouraged. The intense thirst experienced after a hotpot meal is a direct result of excessive sodium intake, which significantly increases the risk of high blood pressure and puts immense strain on the kidneys.
The Hidden Risk in Processed Hotpot Balls
Popular ingredients like beef balls, fish balls, and other processed toppings contain high amounts of phosphate food additives. For individuals with compromised kidney function or those undergoing dialysis, consuming these items can be dangerous. When kidneys cannot efficiently filter out phosphorus, it leads to hyperphosphatemia. Over time, this condition severely degrades renal function and elevates the risk of cardiovascular diseases.
How to Enjoy Hotpot Safely and Protect Your Health
To enjoy a delicious hotpot without compromising your health, experts recommend choosing light broth bases such as seaweed, tomato, or fresh vegetables. Furthermore, changing the order in which you cook your food can make a massive difference:
- Step 1: Vegetables First. Cook and eat vegetables first to create a natural feeling of fullness.
- Step 2: Seafood Next. Cook seafood after vegetables to keep the broth clean.
- Step 3: Meats and Processed Balls Last. Add these ingredients toward the end of the meal to prevent fats and purines from dissolving into the water early on.
Finally, avoid drinking the leftover broth and do not package it to take home. To prevent obesity, avoid eating hotpot late at night. Instead of washing down your meal with beer or sugary sodas, opt for plain water or unsweetened tea to protect your overall health.
