CATDOLL : CATDOLL: Are sea urchins poisonous? Do sea urchins contain toxins?

1. Are sea urchins poisonous? Do sea urchins contain toxins?

1. Sea urchins are poisonous.

2. There are two organs in sea urchins that produce toxins: forked spines and thorns. In the reproductive season, eating the gonads and ovaries of sea urchins or being pricked by spines or forked spines can cause poisoning. Dozens of sea urchins, including white-spined three-line sea urchins, ball sea urchins, poisonous sea urchins, and stone pencil sea urchins, have been reported to be poisonous. The effects of sea urchin toxins vary. Some can cause breathing difficulties, muscle paralysis, convulsions, and even death in animals; some have a dissolving effect on animal red blood cells, and can cause cardiac activation and make muscles unresponsive to indirect stimulation, and have potential medicinal value. In addition, the venom gland extract of white-spined three-line sea urchins has a contractile effect on isolated smooth muscle, and this effect is proportional to the dose of the toxin; the coronary circulation of the mouse heart perfused with intestinal cells produces changes in heart beat amplitude and rate, causing varying degrees of heart block.

3. The white-spined sea urchins also contain toxic heat-labile proteins, whose main function is to release histamine and produce kinins, indicating that this substance has potential pharmacological value. [4] Sea urchin toxins are soluble in water. The spherical forked spines of the white-spined sea urchins contain highly toxic substances. This type of toxin is not dialyzable and is stable in the pH range of 4.3-10.6, but is inactivated at 45.0~47.5℃. The salt water extract of the spherical forked spines of the sea urchins contains toxic substances that are dialyzable, not heat-labile, and are destroyed after being kept warm in a 0.25mol/LNaOH solution for 1-2 hours. It has an effect similar to acetylcholine.

2. Although sea urchins appear to be covered with spines, what are their nutritional values?

Sea urchin is an echinoderm that lives in the sea. Its hemispherical shell is made of hard calcified matter with spines. In the body cavity wrapped by the shell are five small pieces of thick yellow porridge-like substance, namely sea urchin roe. Sea urchin roe is the edible part of the sea urchin, rich in protein, and composed of 17 kinds of amino acids. Its composition ratio is close to that of the human body, and it is easy to absorb and utilize. The fat it contains is unsaturated fatty acid, which can reduce fat and lose weight, and protect cardiovascular and cerebrovascular health.

The Chinese people regard it as a top tonic among seafood. There is a saying that eating sea urchin roe can nourish and strengthen the body, and it is said that it can refresh the mind and enhance physical strength. It is especially favored by some men and is called the crystal of the sea. Sea urchin tastes delicious, can promote saliva secretion, stimulate appetite, strengthen the spleen and appetite, and has a good nourishing effect; it can improve sub-health symptoms such as lack of energy and neurasthenia. Long-term consumption can play a role in strengthening the body and improving immunity.

It contains biologically active substances such as structural proteins and lecithin, which can improve sexual function. It is also rich in hormones, which can nourish yin and tonify the kidney; it contains high fatty acids, which can lower cholesterol and triglycerides, and prevent cardiovascular and cerebrovascular diseases. Chinese medicine also believes that sea urchins have the effects of reducing phlegm and swelling, softening and dispersing nodules, and can be used to treat diseases such as gastric and duodenal ulcers and otitis media. With the development of "Times", people's living standards are also constantly improving, and various seafood have become regular guests on the table. Speaking of seafood, it is Zhanjiang. The unique climate makes the average temperature in Zhanjiang higher than 15℃ for more than 300 days a year, which is really enviable. This climate also provides a good growth cycle for aquatic products.

However, today I am not talking about the seafood in Zhanjiang. Today I am talking about sea urchins. Yes, this small animal is covered with black spines. Do you know the nutritional value of sea urchins? The nutritional value of sea urchins is very high, especially the protein content. According to biologists, every 100 grams of sea urchin roe contains 41 grams of protein, which can effectively supplement the protein lacking in the human body. For people who are not in good health and lack of nutrition, you can eat some sea urchins every day to supplement.

It can supplement vitamins, proteins, cardiovascular and cerebrovascular, prevent cholesterin diseases, and replenish blood. It can improve resistance and immunity, and it can also supplement some thioamine and lecithin.

The nutritional value of jujube is particularly high, and it can be a good supplement, and it can supplement vitamin C, vitamin D, calcium, iron, phosphorus, protein, and fat. It can also improve anemia.

It has nourishing nutritional value, can improve physical conditions, is beneficial to supplement various elements, can enhance resistance, and can also prevent various cardiovascular diseases. It has the function of strengthening the body.

The nutritional value can be said to be particularly high, and it is also a very good seafood food. It can replenish body fluids, delay aging, and create a balanced nutrition.

3. Can sea urchins nourish the kidneys? The name "the essence of the sea" is not undeserved.

Can sea urchins nourish the kidneys? In my country, sea urchins are considered a top-grade tonic. Some people call them "the essence of the sea". Sea urchins are very effective in nourishing the kidneys and strengthening bones. A large number of studies have found that the structural proteins and egg mass phospholipids contained in sea urchins can indeed stimulate male hormones and improve sexual ability. Therefore, eating sea urchins does have a certain effect of nourishing the kidneys.

What foods cannot be eaten with sea urchins? 1. Sea urchins cannot be eaten with cold foods. Sea urchins live in the sea and are cold in nature, so it is best not to eat them with cold foods, which will cause stomach cold, diarrhea, etc. Common cold foods include cucumbers, watermelons, pears, mangosteens, water spinach, etc.

2. Sea urchins cannot be eaten with beer or red wine. Eating sea urchins with beer (or red wine) will produce a lot of uric acid, which can easily cause arthritis. If there is too much uric acid, it will be deposited in the joints, causing arthritis or soft tissue inflammation.

What are the effects and functions of sea urchins? 1. Lower cholesterol

Sea urchins have the effect of lowering cholesterol. They can reduce triglycerides and cholesterol in the human body and enhance the body's immunity.

2. Improve intelligence

Sea urchins contain biologically active substances such as structural proteins and lecithin, which can not only improve kidney function but also enhance intelligence.

3. Prevent cardiovascular disease

Sea urchins contain 17 kinds of amino acids, with high content and good quality. Eating sea urchins regularly can effectively prevent cardiovascular diseases.

4. Nourishing and strengthening the body

Lobsters are scavengers, but they prefer fresh food, including fish, crabs, and sea urchins.

5. How high is the purine content in sea urchins and oysters?

Sea urchin: High, content ≥150mg/100g

Oysters: High, content ≥239mg/100g

During the acute attack of gout, the daily purine intake should be controlled between 100-150 mg, which means that even 50 grams exceeds the upper limit!
