Nowadays, many people take great pains for the healthy growth of their children. When children are young, apart from buying a lot of nutrients, whether domestic or imported, they are mainly beneficial to children and never stingy. In the usual diet, we should also pay attention to a balanced diet. Fruits and vegetables, milk, eggs, etc. Are indispensable. Many people will choose cod. After all, it is balanced in nutrition and rich in DHA, which is very suitable for children.

However, when people go to the supermarket to buy cod, they don't find fresh whole cod, all frozen cod slices. This is because its head accounts for a large proportion and its edible value is low, so traders directly remove the fish head, which greatly reduces the transportation cost.

Therefore, the market is full of headless cod. However, some vendors made a mistake and used a tropical marine fish called "oil fish" as cod. This kind of "fake cod" is no different from the real one in appearance, with few fishbones and thick meat.

However, if you give your child this kind of "oily fish", it is likely that there will be "diarrhea" and even diarrhea. Almost half of the ingredients in "oil fish" are wax esters. Although this substance is not toxic, it can't be digested and absorbed by the human body at all, and it can also stimulate the intestines and make people vomit and diarrhea.

So this kind of fish is not eaten directly, but used as industrial lubricant and laxative.

In fact, there are only three real cod: Atlantic cod, Pacific cod and Greenland cod. You should remember. From the appearance, the head, mouth and stomach of these three kinds of cod are relatively large, which are suitable for children's supplementary food and are very safe and reliable to eat. Except for these three species, the others are fake cod.

Having said that, the most important thing is how to distinguish between true and false cod. When buying, you can pay attention to the following three points:

1. In terms of price, a catty of cod is about 50 yuan, and the quality is good, as high as 150 yuan. Oil fish is much cheaper, and the maximum price is no more than a catty of 25 yuan. If you see cod at a low price, you should be on your guard.

2. In terms of meat quality, the meat quality of cod is white and tender, just like garlic cloves, and the taste is fresh and sweet. However, oily fish is yellow, with rough meat, loose and poor taste.

The last and simplest way is to look at the information on the package. First of all, you can look at the place of origin. Because cod is a cold-water fish, it lives in the Atlantic Ocean and the Arctic Ocean and is produced in Nordic countries such as Iceland, Norway and Sweden. On the contrary, oily fish generally live in tropical and subtropical waters.

As long as you master the above three points, you will no longer be afraid to buy "fake cod". Although cod is good for your health, you should pay attention when eating it. If the baby is 7 to 24 months old, it is enough to eat 50 to 70 grams of cod every week. Eating too much is difficult to digest and absorb, which has a certain burden on metabolism.
