What fish has the least cholesterol and the highest nutrition

Eel (rice fish) is high in cholesterol. The rice fish, 一作鮸鱼 (pronounced miǎn), resembles a sea bass, with a dark, grayish-brown and purple-green body and a grayish-white belly. The upper edge of the dorsal fin spines is black, and the fin strips ** have a longitudinal black stripe.

There is a sunny spot above the axillary part of the pectoral fin. The rest of the fins are grayish-black. The body shape of the rice fish is flattened and elongated backwards on both sides, and the back and abdomen are shallow arcs.

It prefers to inhabit waters with high turbidity. It can make a sound with a swim bladder and is ferocious. Sinking during the day and rising at night; In April and May every year, it swims from deep water to nearshore for reproductive migration.

Carnivorous, mainly small fish and small benthic invertebrates. The adult body of the rice fish is usually 50 cm long and weighs about 2 kg, the largest one can reach 80 cm, and the weight can reach 5 kg, and the body length is twice the body height and the head length is twice the length of the head.

Reproductive reproduction. Rice fish grows faster than yellow croaker, with a body length of about 500 mm and a capacity of 702 million eggs. Different regions have different breeding periods, from July to August for rice fish outside the Yangtze River estuary, May to June for rice fish in Zhoushan Islands, and April to May for rice fish off the coast of Pingtan in Fujian Province.

After spawning, the fish swim back to feeding areas, and some to deeper waters.

Nowadays, many people overemphasize that cholesterol is not good, and some newspapers and magazines mention that scaleless fish has high cholesterol content, so all foods with high cholesterol such as scaleless fish are excluded from the diet. Is the cholesterol content of scaleless fish high? Is it necessary to "expel scaleless fish" from recipes?

First of all, this generalization is not comprehensive, not all scaleless fish have high cholesterol content, but some are relatively high, such as 361 mg of cholesterol per 1 00 grams of whitebait, 177 mg of river eel, 136 mg of loach, 126 mg of yellow eel, 114 mg of cod, and the amount of food can be appropriately limited when eating; However, there are also some scaleless fish with low cholesterol content, such as hairtail fish with cholesterol content of 76 mg per 100 grams, shark with 70 mg, and its content is similar to that of scaly fish, such as grass carp is 86 mg, yellow croaker is 86 mg, pomfret is 77 mg, sea bass is 86 mg, etc. Secondly, the fat of many fish is rich in polyunsaturated fatty acids, especially marine fish, which has the effect of reducing cholesterol content in the body, lowering blood pressure, promoting blood circulation, preventing arteriosclerosis, and preventing cardiovascular diseases, which is very beneficial to human health. In order to judge the effect of a food on blood cholesterol, it is necessary to consider the cholesterol content of the food and the content of saturated fatty acids at the same time.

In general, saturated fatty acids in food have a greater effect on blood cholesterol than cholesterol in food. Therefore, for those with hypercholesterolemia or those who wish to prevent cardiovascular disease, it is important to control the daily total cholesterol and total fat intake, and avoid eating foods containing more saturated fatty acids, such as cream, butter, lard, coconut oil, etc., and control the daily total cholesterol intake within 300 mg. In conclusion, not all phosphate-free fish are high in cholesterol, and even fish with high cholesterol content can still be eaten in moderation as long as the total daily cholesterol intake is controlled.

It is also possible to eat fish with high cholesterol, fish meat contains a large amount of unsaturated fatty acids, which can reduce blood cholesterol and triglycerides, increase high-density lipoprotein, thereby inhibiting blood agglutination, which can play a role in preventing arteriosclerosis.

As we all know, cholesterol is a very important compound in the human body, which is the key to promoting the synthesis of cell membranes and is an important presence in maintaining the health of the human body. However, if the total cholesterol content in the human body is too high, it will have adverse effects on health, so you must pay attention to the diet with high cholesterol, especially avoid long-term intake of too many foods with high cholesterol, so as not to bring threats to health. So, can you eat fish with high cholesterol?

1. Hairtail: Although the fat content of hairtail is higher than that of ordinary fish, most of them are unsaturated fatty acids, which can play a role in lowering cholesterol.

2. Salmon: Salmon is rich in unsaturated fatty acids, which can not only reduce the level of triglycerides in the blood, but also increase HDL cholesterol, thereby enhancing the elasticity of blood vessels.

3. Soft-shelled turtle: soft-shelled turtle has a very good blood-purifying effect, and eating soft-shelled turtle regularly can reduce blood cholesterol, and is very beneficial to patients with hypertension and coronary heart disease.

4. Tuna: The EPA, protein and taurine contained in tuna have a very good cholesterol-lowering effect, and if you eat tuna regularly, it can play a role in reducing malignant cholesterol in the blood, and then increase benign cholesterol, which is very helpful for preventing diseases caused by high cholesterol.
