Various forms of modern pollution are ubiquitous, and you might not even realize when you've developed heavy metal poisoning. What causes heavy metal poisoning without you knowing? An unhealthy diet is a major cause.
Dietary Habits That Lead to Heavy Metal Poisoning
I. Love for Seafood
Due to the spread of pollution, shellfish and saltwater fish have become the primary sources of heavy metals like mercury and arsenic. Therefore, long-term consumption of seafood can lead to the accumulation of toxic substances like heavy metals in the body, harming your health.
Recommendation: It's best to eat no more than one type of seafood per day, and in a quantity not exceeding 100 grams. Opt for smaller-sized seafood whenever possible. Larger seafood are higher up the food chain and tend to accumulate more pollutants. Avoid or eat less of fish heads, skins, internal organs, roe, and shark fins.
II. Frequent Consumption of Traditional Chinese Medicine
Traditional Chinese Medicine (TCM) has long been known for being gentle and having few side effects. Therefore, some people use TCM as a daily supplement, drinking it whenever they feel the need. However, the purpose of some TCM ingredients is to use poison to combat poison, albeit with low toxicity. For example, realgar and cinnabar, common in TCM, contain arsenic and mercury, respectively. Long-term, large-scale use of realgar and cinnabar can lead to the accumulation of heavy metals like mercury and arsenic in the human body, so they must be used with caution.
Recommendation: When taking TCM, you must follow your doctor's advice to determine if the medicine is suitable for your constitution and symptoms, and the maximum duration for use. This way, you can ensure the medicine is effective and avoid improper consumption.
III. Love for Animal Offal
Animal offal is more prone to heavy metal deposition because poultry are often fed with industrial feed of uncertain composition. If an animal consumes unsafe food—for instance, if its feed or drinking water is contaminated with heavy metals like cadmium—the offal is responsible for metabolizing it. Some harmful substances, including heavy metals, will then accumulate in the offal.
Recommendation: Eat animal offal no more than once or twice a week, and limit the portion to no more than 50 grams each time. Additionally, when eating offal, it's best to pair it with more coarse grains and vegetables to supplement your dietary fiber intake.
IV. Love for Canned Beverages
Cans are made of aluminum alloy and have an organic coating on their inner walls to separate the aluminum from the beverage. Some poorly manufactured cans may have areas where the protective coating is missing or too thin during the production process, causing the inner aluminum wall to come into contact with the beverage.
Over time, aluminum elements gradually dissolve into the beverage, which is especially harmful when the drink is acidic or alkaline. According to a survey of 22 types of beverages by researchers, the aluminum content in canned drinks is 3 to 6 times higher than in bottled drinks.
Recommendation: Drink fewer canned beverages; switching to bottled drinks or drinking plain tap water from your own cup is a healthier choice.
