Fish, prized for its delicious taste and nutritional value, has long been a beloved food among the masses. The ever-increasing variety of innovative cooking methods has made fish even more sought after. While fish meat is rich in nutrients, improper consumption methods can harm health and even lead to serious illnesses. Are you aware of these common mistakes when eating fish?
Avoid These Pitfalls When Eating Fish
1.Raw Fish Sashimi Increases Risk of Clonorchiasis
Many people enjoy sashimi, praising its freshness and tenderness. However, consuming raw fish slices significantly raises the risk of contracting clonorchiasis, a parasitic infection that can even lead to liver cancer.Clonorchiasis is a parasitic disease primarily affecting the liver and gallbladder, most commonly contracted by consuming aquatic products containing live clonorchid cysts. This risk is especially high with raw or partially cooked freshwater fish, shrimp, and snails, which often carry the parasite.Many mistakenly believe that marinating sashimi in sauces or vinegar kills parasites and bacteria. However, common seasonings like soy sauce, vinegar, mustard, or alcohol are ineffective against these organisms. Even briefly blanching sashimi in hot water may fail to eliminate live liver fluke cysts if the cooking time is insufficient. Therefore, it's best to minimize sashimi consumption.
2. Consuming Fish Gallbladders for Detoxification May Backfire
Traditional Chinese medicine attributes fish gallbladders with properties to clear heat, detoxify, improve vision, and relieve coughs. Consequently, despite their bitter taste, many are eager to try them.However, fish bile contains highly toxic substances like sodium sulfite, which are heat-resistant and unaffected by alcohol. Thus, whether cooked, consumed raw, or washed down with alcohol, fish bile poses a significant poisoning risk.
Fish gallbladder poisoning acts rapidly and is life-threatening. Mild cases present with nausea, vomiting, abdominal pain, and diarrhea. Severe cases may develop hepatomegaly, jaundice, hepatic tenderness, and renal percussion pain. Without prompt treatment, it can lead to liver and kidney failure, even death. Therefore, fish gallbladders should be avoided whenever possible. Even for medicinal purposes, they should only be consumed under a doctor's guidance.
3. Avoid these two parts when eating fish
As fish age, mercury accumulates in their bodies, with particularly high levels in the brain and skin. The parts with the highest mercury content, in descending order, are: fish head, skin, flesh, and roe.Take crucian carp as an example: in fish under 200g, the mercury levels in the flesh, roe, skin, and brain are all very low, with minimal variation between parts. However, in crucian carp around 400g, the skin's mercury content increases fivefold compared to smaller fish, while the brain's mercury content surges to over 20 times higher.Therefore, when purchasing fresh fish, it is best to choose smaller fish. When eating fish, it is also advisable to avoid consuming the head and skin.
4. Eating fish on an empty stomach may trigger gout
Gout is a disease caused by purine metabolism disorders. Most fish naturally contain relatively high levels of purines. Consuming large amounts of fish meat on an empty stomach, without sufficient carbohydrates to aid digestion, can easily disrupt acid-base balance, potentially inducing gout or exacerbating existing gout symptoms.Therefore, it's advisable to consume starchy foods like multigrain porridge, noodles, or taro before eating fish. During meals, include starchy side dishes such as sweet potatoes, corn, or potatoes to mitigate purine effects and protect your health.
5. Freshly Slaughtered Fish May Contain Residual Toxins
Many believe fish should be consumed as fresh as possible, arguing that slaughtering it alive guarantees freshness and nutritional value. However, this is a misconception. Fish naturally contain certain toxic substances. When slaughtered immediately before consumption, these toxins may not have sufficient time to be expelled, potentially posing health risks.
After purchasing live fish, keep them in clean water for one to two days before consumption. For pre-slaughtered fish, soak them in clean water for about an hour to help expel residual toxins and reduce health risks.Cooking should ideally occur several hours after the fish's death. This is because the connective tissue in fish meat gradually softens after slaughter, enhancing the texture and flavor. Cooking at this stage yields the best taste. Fish is an excellent health food, but consuming it requires proper methods to truly reap its health benefits.
