Health for All says
In recent years, with the improvement of people's health awareness, eating more fish has become a healthy eating habit Xi many people. Fish is a nutritious food that is rich in a variety of nutrients such as high-quality protein, unsaturated fatty acids, vitamins and minerals, and has many benefits for human health. However, some fish may pose a carcinogenic risk in some specific situations, and we need to understand and avoid eating these fish to protect our health.
First of all, many people are familiar with fish that contain too much mercury selenium. Selenium and mercury are both trace elements that the human body needs, but if the levels of mercury in fish are too high, it can pose a potential risk to human health. In general, large fish have more significant bioaccumulation, so these fish have relatively higher levels of mercury. For example, sharks, sailfish, tuna, etc., have more mercury levels in their bodies than safe intake, and long-term consumption may adversely affect the body's nervous system and immune system.
Secondly, the problem of parasites in river fish and lake fish also needs to be paid attention to. River fish and lake fish are susceptible to some parasitic infections during their growth, such as Schistosoma japoiasis, liver flukes, etc. These parasites can cause damage to the liver, gallbladder and other organs of the human body, and even cause serious diseases. Therefore, try to choose fish from formal farms, or cook them before eating, to ensure the hygiene and safety of the fish for consumption.
Finally, the internal organs in the belly of the fish are also something to pay attention to. The internal organs in the stomach of fish, such as fish gall bladder, fish organs, etc., some fish internal organs contain a substance called purine, if excessive intake may lead to purine metabolism disorders, causing gout and other diseases. Therefore, when we eat fish, we should try to avoid consuming too much fish maw internal organs, especially people with gout and other related diseases.
As an experienced old Chinese medicine practitioner, I recommend the following points to pay attention to when consuming fish: First, choose fresh fish and avoid eating fish that has been stored for too long or has rotted. Secondly, try to choose fish with bright scales or fish with more scales, because scales have a certain protective effect and can reduce the pollutants adsorbed on the fish. In addition, eat in moderation, avoid excessive intake, and mix other ingredients reasonably. Finally, adequate handling and cooking before consumption, such as minced meat, slicing, or frying, can reduce parasites and contaminants in the fish.
To sum up, eating more fish is good for the body, but not all fish are suitable for consumption. In particular, fish with high levels of mercury selenium, river and lake fish with parasite problems, and fish with excessive purines in the internal organs of fish maws should be avoided as much as possible. Choosing wisely, eating in moderation, and paying attention to the way it is processed and cooked is the key to ensuring that we enjoy the nutrition of fish.
