Shut up, don’t eat 3 kinds of fish anymore, it may contain formaldehyde and heavy metals, it’s best to throw it away

Fish is known to be a healthy meat promoted by many experts. Compared with other meats, the nutritional value of fish is more prominent, and it has the characteristics of high protein content, easy digestion and high utilization rate.

In terms of nutrition, it is also recommended that you eat foods rich in Omega-deep-sea fish, polyunsaturated fatty acids, which are essential fatty acid components for the human body, and are of great significance to the development of the brain and vision.

It is richer in polyunsaturated fatty acids than shallow water fish. For example, we can choose salmon, yellow croaker, mackerel, golden pomfret, sardines and so on. They are fish that we can eat, which can enhance brain function and keep away from Alzheimer's disease and cardiovascular and cerebrovascular diseases.

Also, in this day and age of increasing numbers of people suffering from depression, a new study has been published in the British Journal of Epidemiology and Community Health. In 16 documents and 26 studies around the world, as many as 150,000 subjects found that eating fish can reduce the risk of depression. Among them, men and women who eat more fish have this effect.

Because there are fish to eat, there are certainly fish that need to be lost. In particular, these fish may contain formaldehyde and heavy metals. Please stop eating them. Those who sell fish never eat it.

Seriously polluted fish: In terms of safety, especially fish living in seawater, due to the living environment, there may be excessive pollutants, such as heavy metals such as mercury, lead, and cadmium.

In addition, in related studies, people are not recommended to eat tilefish, shark, swordfish, etc. And big fish, which are highly polluted. After all, as a species at the top of the food chain, it is more likely to accumulate heavy metals and other pollutants in its body. I suggest you avoid it.

Stale fish: Fresh fish tastes great and can be expensive. The price of stale fish is low, but it is also prone to safety hazards. In particular, the eyes of the fish are no longer transparent and bright, the gills are damaged, the adhesion is serious, and the scales are dull and fall off. The longer the time, the more bacteria are likely to accumulate in the fish. I suggest you stay away from it.

Going to a regular place to buy fresh fish is more secure and the most beneficial to your health.

Some abnormal phenomena: If you buy fish and find that the fish is very lively and always wants to jump out of the water, and you can smell the obvious pungent smell at a close distance, it may be that a bad company adds formaldehyde to the fish for profit. , wrongly making buyers think that this is a lively fish phenomenon.

Everyone must pay attention when buying, and never buy fish with a pungent smell, so as not to suffer from being fooled.
