Does crucian carp contain DHA? What fish is higher in DHA

The amount of DHA in the eggs of common crucian carp should be traceable. Only deep-sea fish.

It is rich in DHA. You can eat more deep-sea fish and seafood on a regular basis. Not eating any fish can increase DHA intake.

Overall, marine fish contain more DHA than freshwater fish, and deep-sea fish generally contain more DHA than coastal and offshore fish. Based on the results of existing research and analysis, nutritionists have developed a reference table for the order of fish with rich DHA content:

1) Freshwater fish. Anchovy, crucian carp, blackfish, mandarin fish, blueeye trout, bream, herring, silver carp, etc. This is in order of the relative content of DHA in the unsaturated fatty acids of the fish.

2) Marine fish. The size of the fish according to the percentage of DHA content in the fish is as follows: tuna, mackerel, saury, sardines, moray eel, rainbow trout, salmon, horse mackerel, herring, hairtail, swordfish, bonito.

For tuna, mackerel, saury, and sardines, the DHA content in 100 grams of fish meat is more than 1 gram, which can be described as a veritable "DHA fish", and the amount of DHA contained in tuna is as high as one gram, and the total amount of fatty acids is up to one gram, which is actually the "top among fish".

Other fish such as flounder, octopus, cuttlefish, etc., contain only a small amount of DHA, and generally do not exceed one gram in 100 grams of fish meat.

Nutritionists also pointed out that the DHA content of some fish is not high, but the fish oil is rich in DHA, especially rainbow trout, salmon, cod, bonito, cuttlefish, etc., which should be paid attention to when purchasing.

Another question worth paying attention to is: will the DHA of fish be reduced after cooking? Nutritionists believe that cooking methods do have a relationship with DHA absorption.

According to the experimental determination of sardines conducted by Japanese experts, whether fried, boiled, grilled, dried or raw, the DHA content in sardines does not change and can be absorbed by the human body, but the proportion of fried sardines DHA is reduced. Therefore, in order to make more efficient use of DHA in fish, the fish frying method should be used sparingly during cooking to reduce the loss of DHA.

Fish with high DHA content are: anchovy, crucian carp, black fish, mandarin fish, herring, hairtail fish, etc.

DHA stands for docosahexaenoic acid, which is a polyunsaturated fatty acid necessary for the human body, and is abundant in fish oil. It is a straight-chain fatty acid containing 22 carbon atoms and 6 double bonds.

Since the 80s, developed countries such as the United States, Japan, the United Kingdom, and Australia have begun to produce and use DHA. In the early days, such products were mostly made from deep sea fish oil (usually tuna oil) rich in DHA and EPA through molecular distillation, and existed in a mixture of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), commonly known as omega-3 or ethyl polyenoate. The state-of-the-art products are made by fermentation of DHA-rich, EPA-free marine microalgae.

Hairtail contains DHA, DHA is one of the nutrients needed by the brain, which is very important for improving memory and thinking ability.

Hairtail fish has a high fat content, and most of them are unsaturated fatty acids, which have the effect of lowering cholesterol and can also lower blood lipids. It is beneficial for patients with high blood pressure and heart disease.

It is a high-fat fish containing protein, fat, vitamin B1, vitamin B2 and niacin, calcium, phosphorus, iron, iodine and other components.

It has the effect of nourishing the spleen and invigorating qi, warming the stomach and liver, moisturizing **, nourishing qi and nourishing blood, and bodybuilding, and at the same time, the hairtail has the effect of nourishing the spleen and nourishing qi, moisturizing and nourishing hair, preventing cardiovascular diseases and preventing cancer, and improving intelligence, and its nutritional value is also very high.

Some of the unsaturated fatty acids in the hairtail fish have the effect of lowering cholesterol, and some of the lecithin in the hairtail fish can reduce the mortality of cells and delay aging. In addition, hairtail fish have higher levels of DHA and EPA than freshwater fish, and DHA is a nutrient needed by the brain to improve memory and thinking skills.

Hairtail fish is very rich in lecithin, and generally has the function of nourishing the brain more than freshwater fish.

If there is more than 1 gram of DHA in 100 grams, this fish is called DHA fish.

DHA fish = 100 grams of fish meat contains more than 1 gram of fish, including: tuna (fatty part), division fish, goldfish, saury, eel, sardines, and fish roe.

Fish with DHA content of less than 1 gram and more than hundreds of milligrams are: rainbow honor, herring, salmon, horse mackerel, squirt, Japanese prongtoothfish, chicken fish, conger eel, jade tendon fish, crucian carp, oil fish, firefly fish, hairtail fish, mullet, sailfish, alfonsino snapper, monarch fish, hard fish, etc.

Fish that contain a small amount of DHA are: supergrade fish, carp, sea bass, flounder, flounder, eel, swallow ray, swallow, bighead, octopus, cuttlefish, oysters, etc.

Salmon and tuna contain a lot of DHA. However, it is not recommended for infants and young children to use fish DHA, one is the pollution of the environment and food chain, and the other is that fish DHA contains high EPA content, which is not suitable for babies. It is recommended that you choose an algae-derived DHA supplement.

EPA content is low and does not pass through the food chain.

1. What is DHA?

DHA is known as the brain ** and intelligence factor, which shows its important role in the development of the baby's intelligence. By supplementing DHA, it can promote fetal brain development, play an important role in the maturation of retinal photoreceptor cells, and can also improve the development of brain cells, reduce postpartum depression in pregnant women, and reduce the occurrence of postpartum depression in sufficient amounts of DHA.

2. What foods are rich in DHA

1. Breast milk. Breast milk contains a high amount of DHA, and generally speaking, the amount of DHA in a mother's milk depends on the food structure of the meal. For example, if the mother eats more fish, then the DHA content in the breast milk is much higher.

2. Formula milk powder.

One of the biggest foods that children absorb DHA from** is formula with DHA, which contains not only DHA but also other nutrients.

3. Fish. Fish are rich in nutrients, sardines, hairtail, tuna, yellow croaker, salmon, crucian carp, etc., these fish are rich in DHA content, if you want to supplement DHA, you may wish to choose these fish.

4. Dried fruits.

The A-linolenic acid contained in some dried fruits can be converted into DHA in the human body, such as walnuts, almonds, peanuts, sesame seeds, etc.

5. Algae. DHA is also abundant in algae.

6. DHA products.

DHA can be extracted from deep-sea fish oil and algae to be made into DHA products that can be marketed.

Pregnant women can eat these DHA-rich foods to promote the development and growth of the fetus, but they should also pay attention to other aspects of their diet, eat healthy and nutritious.

Fish with high DHA content include tuna, bonito, salmon, mackerel, sardines, horse mackerel, sailfish, tuna, yellow croaker, saury, eel, hairtail, crucian carp, etc., and the DHA content per 100 grams of fish can reach more than 1000 mg. For a certain type of fish, eye socket fat is the first part of the fish with high DHA content, followed by fish oil.

Why does fish oil contain DHA?

There is a plant in the ocean that contains a lot of linolenic acid, called phytoplankton. This phytoplankton is a tiny algae suspended in the water, which is tiny and invisible to the naked eye, but fills the upper layers of the ocean, and is the basis of the ecological balance in the water. Zooplankton in the ocean, such as amoebae and flagellates, feed on phytoplankton and survive by eating phytoplankton.

After eating phytoplankton, the linolenic acid contained in phytoplankton is converted into DHA and EPA in zooplankton.

If you look at the fish in the sea, small fish eat zooplankton, and fatty acids such as DHA and EPA (essential fatty acids for humans) gradually accumulate in the small fish due to the continuous consumption of zooplankton.

Medium fish eat small fish, big fish eat medium fish, and humans eat large fish (some fish eat phytoplankton directly, converting linolenic acid into EPA and DHA in the body).

It all started with phytoplankton, or rather, with the linolenic acid contained in phytoplankton.

The cooking method of fish varies depending on the DHA.

When eating fish, different cooking methods can affect the utilization of unsaturated fatty acids in the fish. DHA and EPA in fish are not reduced or spoiled by heating, nor are they altered by preservation methods such as freezing, cutting or cutting to dry. When steaming fish, a small amount of the fat of the fish dissolves into the soup during the heating process.

However, when steaming fish, there is less soup, so there is less loss of unsaturated fatty acids, and the DHA and EPA content will remain more than 90%. However, if the fish is grilled, the fat of the fish will dissolve and be lost as the temperature rises. When the fish is stewed, the fat of the fish will also dissolve in small amounts, and oil slicks will appear in the fish soup.

As a result, DHA and EPA in grilled or stewed fish are reduced by about 20% compared to before cooking. The loss of DHA and EPA when frying fish will be greater, and only 50% or 60% will remain. This is due to the fact that during the frying process, the fat in the fish gradually dissolves into the oil, and the oil components gradually penetrate into the fish.

The first choice for 100% intake of DHA and EPA is raw food, followed by steaming, stewing, and roasting. But there's no need to think that fish has to be eaten raw, or that it should never be fried. DHA and EPA are very easily absorbed in the body, 60% to 80% of the intake can be absorbed in the intestines, so you don't have to worry too much about a little loss.

After all, the diet pays attention to color, aroma and taste, and eating it with flavor is more beneficial to health.

When frying fish, try not to use corn oil and sunflower oil, because these cooking oils contain linoleic acid, which can hinder the absorption of DHA and EPA.

Dried products of fish are usually cut open and dried in the sun, and although they are exposed to air and ultraviolet rays for a long time, the loss of DHA and EPA is negligible.

As long as it is a fish in the deep sea, it is very rich in DHA, and as long as it is a fish, it contains DHA. So if you want to supplement DHA, you can eat more deep-sea fish, and the scallop fish, sea cucumber, abalone, and crab we usually eat are very rich.

I think tuna is rich in dacha, so many people are buying this tuna now, and I think the content of deep-sea fish is also very high.

Marine fish: marine fish (in order of size according to the percentage of DHA content in the flesh): tuna, tuna, fisherman, mackerel, saury, sardines, moray eel, red trout, salmon, horse mackerel, herring, ginseng, hairtail, mullet, swordfish, alfonsino, kingfish, skipjack.

Deep-sea fish is rich in DHA, which is called linolenic acid, linoleic acid and fish and shallow water fish do not contain DHA, so being drunk by pregnant women or children eating deep-sea fish can supplement DHA needed for brain development

Fish should be rich and go away, and I think all fish should be like this, and there are a lot of high quality in blind fish, so I like this kind of fish!

Fish rich in DHC are basically fish from the ocean. The freshwater fish on our side is relatively small, so we should eat more marine fish.

Generally, deep-sea fish contain DHA because these deep-sea fish are relatively high in nutrients, for example, salmon is one of them.

Generally speaking, it is the kind of marine fish that is rich in DHA, because if this marine fish is used, it is definitely very good for pregnant women to eat more.

Generally speaking, some deep-sea fish are rich in DHA, such as tuna, which are abundant.

There are also cold-water fish such as sturgeon, sea bass, cod, blue flag tuna, etc., as well as deep-sea fish.

Generally, deep-sea fish contains a lot of well, so pregnant women should eat more deep-sea fish, and ordinary people should also eat more fish, seafood and the like have lecithin.

It seems that salmon contains more of this substance, and you can go and eat some salmon, which is better.

Generally speaking, there are many fish rich in DHA, such as red sweet, saury, eel, sardines, and so on.

A lot of fish are rich in DHA Well, like marine fish, the hairtail fish we often eat, herring, sardines are rich in DHA

Generally, deep-sea fish are rich in DHA, so we often have to eat some deep-sea fish to supplement vitamins.

I think all fish are rich in this thing, especially some deep-sea fish, which should be more abundant.

Generally, it is fish in the deep sea, and it may contain this, and it is good for the body for the first time, so it is generally recommended to eat fish in the deep sea.
