Let's first understand what a scaleless fish is.
A fish without scales is a fish without scales. Common scaleless fish are: eel, loach, catfish, river eel, stickleback, whitebait, Spanish mackerel, hairtail and pomfret. In fact, most people think that fish without scales are scaly, but they are too small to see clearly. For example, the silver on the surface of hairtail and pomfret is extremely fine scales, and the scales of eels are smaller and can only be seen under a microscope; The scales of whitebait are so small and transparent that they are almost invisible.
From the analysis of nutritional components, the nutritional value of scaleless fish is particularly high, and it is rich in high-quality protein and unsaturated fatty acids, including EPA and DHA. According to research, eating this kind of fish regularly is very helpful for balanced and comprehensive nutritional value.
With so many benefits, why do rural old people say they eat less?
In fact, it's not groundless ~ ~ Like the elderly, they suffer from diseases such as hypertension and hyperlipidemia. If they don't take medicine at ordinary times (especially in rural areas, they don't pay attention to their health), once they eat a lot of fat (high-quality protein fish), it's easy to make their blood pressure and blood lipids suddenly rise, and their bodies will be uncomfortable.
Another reason is that Chinese medicine believes that scaleless fish are warm and easy to generate heat. If it is a hot constitution, it is easy to cause constipation. Therefore, over time, there has been a saying about the rural elderly ~ ~ As for the above statement, in fact, as long as you eat in moderation, there is no problem. People who eat so much normal constitution at once can't stand it.
Let's talk about dirty fish without scales. Misgurnus anguillicaudatus, Monopterus albus and catfish do make holes in the mud, but after eviscerating, the fish will be clean. Other kinds of scaleless fish also live in clean water, so the statement that scaleless fish is dirty is untenable.
Let's start with the problem of high cholesterol. There are many kinds of scaleless fish, and their cholesterol content is different. For example, eels have more cholesterol; However, whitebait, loach and mackerel are rare. Therefore, it is wrong to think that the cholesterol of scaleless fish is too high to eat. You only need to change the kind of food, so you don't need to think about cholesterol.
Finally, the experts came to the conclusion that scaleless fish is rich in nutrition. As long as it is fresh scaleless fish and people who are not allergic to fish, moderate consumption is healthy.
So which fish are good for the elderly?
Fawei
We call hairtail saury here, which is also a common fish in the market all year round. Hairy fish is tender, not fishy and easy to digest. From this perspective, it is very suitable for the elderly. But also contains rich nutrients, such as protein, fat, various vitamins, nicotinic acid, calcium, phosphorus, iron and iodine.
In addition, when making hairtail, it should be noted that it is best not to dispose of the scales of hairtail, because the scales of hairtail have the function of lowering cholesterol, which is very suitable for people with three highs. Chinese medicine experts believe that hairtail is warm, nourishing blood and tonifying deficiency, and has an appetizing effect.
sardine
Sardines are slender whitebait, which is rare here. They are usually canned fish. Sardines are fresh and tender, high in fat, and also contain fatty acids, which can help blood flow smoothly and benefit cardiovascular and cerebrovascular health, so eating them in the elderly is beneficial to health. But elderly people with high uric acid can't eat it because sardines have high purine content.
trout
Salmon, also known as salmon, is a deep-sea fish (also very expensive). Rich in vitamin D, it can promote the absorption and utilization of calcium. Especially for the elderly, the body needs calcium supplement, so you can eat some in moderation. Moreover, the nutritional value of salmon is that it is rich in unsaturated fatty acids, which helps to lower blood pressure, reduce blood fat and soften blood vessels, and is indeed good for the body.
