Fish (鱼肉) refers to the meat of fish. There are many types of fish, and the main edible freshwater fish include carp, grass carp, crucian carp, Mandarin fish, etc., while saltwater fish include yellowtail, scallop, and flatfish. They are all characterized by tender and tasty meat, rich in nutrients, and a good source of some vitamins and minerals.

Fish contains nutrients:

Fish is lean, 100 grams of fish contains less than 2 grams of fat, while 100 grams of sausage contains more than 10 grams of fat. Even the greasiest Norwegian salmon contains half the calories of a pork chop. Fish is also an important source of protein. Fish is easily absorbed by the body, and 100 grams of fish guarantees half of the body's daily protein needs. Fish also supplies the body with vitamins A, D, E and so on. Fish also contains a variety of fatty acids, which can prevent blood viscosity from increasing, effectively preventing heart disease and strengthening the brain and nervous tissue and the retina of the eye. For pregnant women and infants, these fatty acids are even more indispensable. A recent study by scientists shows that fatty acids also play a role in the treatment of chronic inflammation, diabetes and some malignant tumors.

Fish is also high in sodium, which is good for maintaining the body's mineral balance. Fish supplies selenium, iodine and fluoride in a natural way. Therefore, there is no need to worry about absorbing too many trace elements. Salmon contains the most selenium, while river fish contains half as much. Eating 100 grams of fish a day will satisfy the body's daily need for iodine, thus preventing thyroid disease. Magnesium is also indispensable to the body. When there is not enough magnesium in the body, one will feel depressed. At this time, you can eat fish to make up for the lack of magnesium, to achieve the purpose of improving mood. For students, eat more fish can promote brain activity, knowledge learning fast, remember.

Fish is delicious, whether it is meat or soup, are fresh and tasty, appetizing, is people's daily diet more favorite food. There are many types of fish, roughly divided into two categories of saltwater fish and freshwater fish. But whether it is saltwater fish or freshwater fish, the nutrients it contains are generally the same, the difference is only the amount of various nutrients. Fish nutritional value is very high, it has been found that children often eat fish, its growth and development is faster, the development of intelligence is also better, and often eat fish, people's bodies are more robust, life expectancy is also relatively long, the mystery lies in the following nutritional characteristics of fish:

1. Fish contains folic acid, vitamin B2, vitamin B12 and other vitamins, there is a tonic stomach, diuretic, swelling, through the breast, Clearing heat and removing toxins, stopping coughing down the efficacy of a variety of edema, edema, bloating, oliguria, jaundice, breast milk are effective;

2. Fish consumption of pregnant women, fetal restlessness, pregnancy edema has a very good therapeutic effect;

3. Fish is rich in magnesium, the cardiovascular system has a very good protective effect, is conducive to the prevention of hypertension, myocardial infarction and other cardiovascular diseases;

4. Fish is rich in vitamin A, iron, calcium, phosphorus, etc., often eat fish and liver tonic blood, skin and hair effects.

5. Rich in complete protein. Fish contains a large amount of protein, such as yellowtail 17.6%, 18.1%, mackerel 21.4%, silver carp 18.6%, carp 17.3%, crucian carp 13%. The proteins contained in fish are all complete proteins, and the amount and ratio of essential amino acids contained in proteins are most suitable for the needs of the human body, and are easily digested and absorbed by the human body.

6. The fat content is low, and mostly unsaturated fatty acids. The fat content of fish is generally low, most of them are only 1% - 4%, such as yellowtail with 0.8%, scallop with 3.8%, mackerel with 4%, silver carp with 4.3%, carp with 5% crucian carp with 1.1% bighead carp (fathead minnow) only 0.9%, cuttlefish only 0.7%. Fish fat is mostly composed of unsaturated fatty acids, unsaturated fatty acids have a longer carbon chain, has the effect of lowering cholesterol.

7. Higher content of inorganic salts and vitamins. Marine fish and freshwater fish are rich in sulfur, also contains phosphorus, calcium, iron and other inorganic salts. Fish also contains a large amount of vitamin A, vitamin D, vitamin B1, niacin. These are nutrients that the body needs.

In addition, the muscle fiber of fish meat is relatively short, protein tissue structure is loose, water content is more, therefore, the meat is more tender, and livestock meat compared to eat more feel soft and tender, but also easier to digest and absorb. Therefore, it can be seen, fish has a high protein, low fat, vitamins, minerals rich, good taste, easy to digest and absorb the advantages.

Toxic substances in fish

There are a lot of toxic substances in fish because all the pollution is discharged into the sea. When we go to the market and buy fish, more than half of the fish you buy and check contain excessive amounts of persistent organic pollutants, called POPs, which as the name implies, are synthesized by humans and remain in the environment permanently without being broken down, like DDT, like dioxin, which are very well known. And these permanent organic pollutants, usually through the food chain, can accumulate from trace levels to tens of thousands of times more. Because it accumulates in the fat of the animal, and then the big fish eat the little fish, and the little fish eat the shrimp, and it's a very long food chain, and it's a very scary thing to be able to accumulate these very minute amounts of toxins ten thousand times over.

How harmful are POPs to the human body? Teratogenic, carcinogenic, mutagenic, the triple toxin, which is extremely chronic and toxic to the liver, to the kidneys, to the internal organs, to the nerves, to the endocrine system, and also to the reproductive system. So people need to think, eat these things in, will get some inexplicable diseases cause often can not find out? The reason is that there is a lot of very toxic stuff in there. Know how much damage Diosynth can do to a person? For example, one hundred millionth of a gram of dioxin can poison a person to death, and that amount that cannot be seen by the naked eye can poison an adult to death, how toxic it is! Short-term exposure to high concentrations of HCB can cause respiratory failure and premature death of newborns, which are very toxic. People who study biochemistry have gathered some information on this, and it's really, really scary. Gender dysphoria and reproductive disorders are all related to these things, and it's all from eating.
