However, different kinds of fish have different nutritional values. In the process of daily diet, it will be more beneficial to your health to choose different fish to eat according to your nutritional needs.
Eating fish has many benefits. What are the nutritional values of different fish?
We might as well introduce several common fish:
First, the freshwater fish part:
Such as crucian carp, carp, grass carp and so on. Most of them have diuretic and repercussive effects, and they are rich in more than 20 kinds of nutrients such as potassium, phosphorus, cholesterol, calcium, vitamin A and protein. Proper consumption of freshwater fish plays a significant role in maintaining the nutritional balance of the body.
Moreover, compared with other meats, freshwater fish has one of the biggest characteristics, that is, the fat content is almost 0, 100 g, and the cholesterol content in freshwater fish is even only 86mg, which is very suitable for dieters and patients with metabolic symptoms such as hyperlipidemia and diabetes.
Followed by the marine fish part:
For example, Longli fish, Basha fish, sardines and so on. Deep-sea fish are more suitable for the elderly with bad teeth and children with immature mouths because of their more developed muscles, fewer fishbones, tighter muscle fibers and richer protein.
In addition, marine fish are generally rich in fat, but most of them are unsaturated fatty acids. Proper consumption helps to clean blood vessels, improve the quality of cholesterol, and has a good effect on preventing cardiovascular and cerebrovascular diseases. Even DHA rich in deep-sea fish can help promote brain development and nourish nerves.
To sum up, eating fish and what fish to eat have their unique nutritional significance, but although eating fish has many benefits, there are also precautions in the process of eating. After eating some special parts, it is easy to have negative effects on health.
Friends who eat fish should pay attention! These two parts are "dirty and poisonous", so it is best not to eat them?
The first is fish gall.
The function of fish bile is somewhat different from that of human gallbladder. It is not only used to secrete bile, but also used to store secretions produced by liver metabolism, and then used for gastrointestinal digestion of fish.
Therefore, the concentration of metabolites and bile secretions in fish bile is very high, which is naturally harmful to health. Not only that, if you accidentally puncture the gallbladder when cooking fish, it will directly ruin the taste of the whole dish. In order to make delicious fish meal, please handle it carefully and don't eat it by mistake.
Then the fish head, even many people like to eat:
I believe everyone has heard of the dish of fish head with chopped pepper, and many people also have a special liking for fish head.
However, from a health point of view, fish head contains two parts: fish brain and fish gill, both of which contain a lot of heavy metals and metabolites. Especially in recent years, river pollution is more serious, and the level of heavy metals in fish heads has also improved.
Therefore, in general, it is not recommended to eat fish heads, but if you really like them, it is also recommended to choose specific fish for dishes such as chopped pepper fish heads, such as younger fish with less metabolites and heavy metals accumulation, or deep-sea fish with less pollution possibility.
Fish is delicious, but as mentioned above, only when you eat it properly can you eat it healthily and safely. Besides special parts, you can't eat fish, and there are other taboos to pay attention to.
What other dietary taboos are there when eating fish?
It is best not to eat on an empty stomach.
It seems nothing to eat fish on an empty stomach, but many fish have high purine content. If you eat more purine on an empty stomach, it will easily stimulate the stomach, leading to inflammation and ulcer aggravation.
Therefore, before eating fish, you might as well eat two more bites of rice and wait until your stomach can be "padded" before you start tasting, which is healthy and delicious.
② Don't use river fish for sashimi.
The growing environment of rivers is very suitable for bacterial reproduction. Therefore, most river fish also carry some bacteria and parasites, and they can only be safely eaten if they are cooked.
On the contrary, if river fish is used as sashimi, bacteria and parasites will directly enter the human body, causing infection. However, most deep-sea fish have no parasites that can threaten the human body because of living environment factors, so they can be selectively sashimi.
In a word, although eating fish has many benefits, it is necessary to eat healthily. Not only fish, but also any food. Only by careful collocation and reasonable nutrition in daily diet can it be more conducive to good health.
