So what are the benefits of eating eels? What are the effects and functions of eels? Let me introduce to you the effects and functions of eels, I hope it will be helpful to you.

Eel's efficacy and function

1. Lower blood sugar

Eel contains a special ingredient - eelin, which is an active hormone in the eel's body. It can exert the effect of insulin in the human body and has a certain effect of lowering blood sugar. It is very suitable for diabetic patients to eat and assist in the treatment of the disease.

2. Protect liver and improve eyesight

Eel also contains a lot of vitamin A, which is a fat-soluble vitamin essential to the human body. It plays an important role in the liver and retina of the human body. It can relieve the aging of liver cells and enhance liver function. It is also the main raw material for the synthesis of rhodopsin and enhances vision.

3. Promote recovery

Eel, like loach, is a commonly used tonic and is most suitable for consumption during weak periods such as after illness and childbirth. Eel is a high-protein food and contains a lot of protein. Eating it when the body is weak can promote recovery.

4. Enhance brain power

Eel contains a small amount of fat, but most of it is unsaturated fatty acids. This type of fatty acid is an effective substance for promoting brain development and has a good inhibitory effect on memory loss in the elderly.

5. Beauty and skin care

Eel contains high levels of vitamin A and vitamin C, both of which are powerful antioxidants. After consumption, they can remove free radicals in the body, relieve the aging of various organs and skin, and have a strong beauty-enhancing effect.

6. Nourishing blood

Eel contains a large amount of protein and a relatively large amount of the mineral iron. These two substances are the main raw materials for the synthesis of hemoglobin and have a certain blood-replenishing effect after consumption.

7. Enhance immunity

Yellow eel is rich in cholesterol, which can maintain cell stability, increase the flexibility of blood vessel walls, maintain normal sexual function, and enhance immunity.

8. Regulate the balance in the body

Rice field eel is rich in phosphorus, which plays a role in forming bones and teeth, promoting growth and repair of body tissues and organs, providing energy and vitality, and participating in the regulation of acid-base balance.

How to choose eel

1. Cage the seedlings

There are two sources of eel seedlings: artificial breeding and natural capture. Artificial breeding seedlings have stable quality, but are currently very rare and cannot meet the needs of artificial breeding; the main methods of catching eels in natural waters include cage capture, electric capture, needle fishing, drug capture, needle fork and hand capture, among which only cage capture seedlings have a high survival rate, while the survival rate of seedlings obtained by the other methods is low. There are currently "artificially bred", "extra large eels", "Thai eels", "Japanese eels" and so on.

2. Deep yellow spotted eel

This type of eel is fat and strong, with dark yellow body color, irregular brown-black spots on the back and sides, and the spots are connected to form several lines on the back and sides from the front to the back of the body. It is docile, grows fast, and is suitable for artificial breeding. The earthy red large-spotted eel is also a high-quality eel species, but the number is small. The light yellow and blue-gray fine-spotted eel grows slowly.

3. No disease

If the eel has obvious red bloody rotten lesions on its body, it is skin rot; if the tail is white and fluffy, it is Saprolegniasis; if the head is large and the body is thin, or even stiff and curled and trembling, it is internal parasitic disease; if the anus is red, swollen and inflamed, it is enteritis. Eels with these diseases should be removed when selecting.

4. No Injury

The most common ones are pinholes in the mouth, abrasions on the head and abdomen, and pinholes on the body. Abdominal abrasions are difficult to find if the abdomen is not facing upwards, so you should pay attention to check. If you pour the yellow eel into 3%-5% salt water, the injured individual will jump up immediately, and this type of eel is also eliminated (but some particularly sensitive healthy eels will jump up, so you should check the appearance and carefully identify them).

5. The body surface should be smooth, with abundant mucus and no shedding

For sick, injured or poisoned eels, the mucus on the whole body or part of the body has fallen off or decreased, and the eel has no smooth feeling or weak smoothness when grasped by hand, or the mucus obviously falls off when the eel is lifted. Such eels are not suitable for eel seedling breeding. Once the eel loses the mucus that acts as a barrier, it cannot survive.

6. Be strong in escaping

A healthy eel will feel hard when grabbed by hand, and will have great power to struggle to escape. An unhealthy eel will feel sticky when grabbed by hand, but will be soft and weak, with both ends drooping.
