These 4 common fish, or carrying heavy metals, are not good for the body, doctor: It is recommended to eat less
I don't know if my friends have found such an interesting pattern. "That is to say, many people would rather eat something that flies in the sky than run on the ground, and would rather eat something that swims in the sea than something that flies in the sky."
Indeed, in general, beef and pork are not as nutritious as chicken, duck meat is nutritious, chicken and duck meat are not as nutritious as fish in the sea.
From a nutritional point of view, the nutritional value of fish in water is indeed higher than that of pork, beef and lamb on land, because protein and unsaturated fatty acids in water are more easily absorbed and utilized by the body.
Eating more fish is especially suitable for growing children, because fish can enhance the body's metabolism and improve memory. Eating more fish not only helps to supplement the vitamin nutrition that the human body lacks, but also protects eyesight and promotes brain development.
But not all fish are suitable for everyone to eat with confidence. Some fish don't eat well in the sea, they don't provide nutrients, and they can damage their health. Do you know what kind of fish it is?
These four common fish, or carry heavy metals, are harmful to the body, doctor: It is recommended to eat less
- Very red fish
Generally speaking, most of the fish we usually buy are white. If the fish you bought is red, it means the fish has gone bad. Stop eating this meat.
The reason the fish turns bright red in color is that histidine is produced after spoilage. This substance is a type of bacteria that easily and quickly breaks down the nutrients in the fish itself, and is red in color.
- Freshly slaughtered live fish
Fish can't eat for a long time, just clean fish can't eat too much, no matter artificial breeding or wild catch, these fish will have metal elements more or less, these metal elements enter the body and will affect people's health, if the fish catches immediately Eating, heavy metals are easily absorbed and used by the body.
It is recommended that after slaughtering live fish, leave it for at least half an hour before cooking, and the metal element content in the body will be reduced by more than half.
- Large fish
For large fish that usually live in the ocean, the animals are usually at the top of the marine food chain. Foods at the top of the food chain have higher levels of toxins, especially large fish in the ocean, where mercury levels are more than 10 times higher than normal fish, according to a study.
When choosing fish, try to choose common fish, and don't eat too much fish.
- Sashimi
Those who often watch Japanese dramas or Japanese movies know that because Japan is close to the ocean, they prefer to eat sashimi, but in recent years, I don't know when China started eating sashimi, but the meat can have adverse health effects .
Because we have lived in the sea for a long time, fish will have some parasites and bacteria more or less. If we don't cook these bacteria and viruses at high temperatures, they can enter the body with the fish.
Mildly causing abdominal pain, severe diarrhea can damage the digestive function of the gastrointestinal tract, so when eating fish, it must be thoroughly cooked, so as to better kill the parasitic bacteria in the meat.
Seeing this, many people will wonder why Japanese people often eat sashimi, but their bodies are still very healthy?
This is due to the differences in the physical quality of people in each country and region, because the Japanese stomach has long been accustomed to this kind of sashimi, and they generally do not drink too much hot water. Their stomachs have been exercised very strong. We can only envy this, but we cannot learn.
Conclusion: The Chinese people's stomach developed the habit of eating cooked food a long time ago. If the food is not fully cooked, it will affect the normal functioning of the stomach after eating. For health, it is best not to eat too strange food.
