The end of the year is the time for frequent dinners, sea cucumbers, abalone, bird's nests, shark's fins, the four great delicacies are common on the table noble ingredients. Warm medicine attached to a hospital dietitian Wang Chao pointed out that, due to the output of small, rare for expensive reasons such as noble ingredients expensive, but does not indicate that the more expensive the more nutritious. From the food composition to analyze, any food includes seven nutrients, just a variety of nutrient content is different. Noble ingredients have Chinese medicine theory as the basis for its specificity, in fact, some of the "civilian" ingredients of a certain nutrient and its very close.

Sea cucumber has less protein than shrimp

Japanese ginseng and Northeastern ginseng are the best-selling tonic. But the sea cucumber's high protein is not as high as shrimp and prawns. Nutritionist Wang Chao took China's food composition table and compared it with 100 grams of sea cucumber, which contains 16.5 grams of protein, or only 6 grams after being soaked in water, compared with 13.3 grams of eggs, 30.7 grams of shrimp and 17.5 grams of river crabs. Sea cucumbers are also not particularly high in vitamin A, containing only 11 micrograms compared to 19 micrograms for shrimp skin. But the most notable feature of sea cucumbers is their low cholesterol and fat content.

Improper eating and cooking of sea cucumber is not only detrimental to nutrition, but even harmful to the body. For example, eating raw sea cucumber, although retaining the nutrition and flavor, but may carry a large number of microorganisms, bacteria and even viruses, often eat may be infected with disease. In addition, the most common processing method of sea cucumber is to hang salt at high temperature, that is, the salted sea cucumber seen on the market, in the process of consumption will undergo a long period of high-temperature boiling and soaking, most of the nutrients have been lost.

Abalone is rich in globulin, which is not absorbed by the human body

It is said that abalone contains the most immunoglobulin in the food, and long-term consumption can enhance the body's immunity. Nutritionist Wang Chao pointed out that the consumption of abalone to supplement the body's immunoglobulin statement is wrong. The human body can synthesize its own immunoglobulin, and the need for live immunoglobulin, and want to eat abalone to increase the body's immunoglobulin, not possible.

And from the nutritional composition to analyze, abalone and snails, arkshells are high protein and low fat. 100 grams of abalone protein content is 12.6 grams, snails is 11 grams, arkshells is 10 grams. After removing water, the protein content of their dried products are all above 50%. In terms of mineral content, although abalone is extremely rich in iron and calcium, this is a ****same characteristic of shellfish and not a unique advantage of abalone. In fact, its calcium content is much lower than that of field snails, while its zinc content is much lower than that of mud cockles, and only its sodium content is the most prominent, which is also the reason for its freshness.

Bird's nest is good for your face, but you need to eat it continuously for a long time

Hu Tingting, a nutritionist of Municipal Hospital of Traditional Chinese Medicine, pointed out that bird's nest mainly contains water-soluble proteins and amino acids. 100 grams of bird's nest is low in fat (0.35 grams), which is lower than that of tofu and eggs; the total amount of essential amino acids contained in bird's nest (18.64 grams) is the highest while that of ginkgo ear (2.22 grams), tofu (3.47 grams) and egg (4.61 grams) is the highest. 4.61 grams. In fact, the protein content of bird's nest is not high, far less than pig's trotters and cow's trotters, but the protein it contains is mainly water-soluble collagen.

"The real beauty of bird's nest is not its collagen, but its ability to nourish yin and replenish qi, moisturize the lungs and remove dryness, and when people consume it with a good constitution, their skin will naturally shine." Chen Zhiwei from the Department of Traditional Chinese Medicine and Dermatology of the City Hospital of Integrative Medicine said. Due to the calm nature of bird's nest, it should be eaten several times a week and for a long period of time to be effective, and it is impossible to expect the miraculous effect of skin beautification after eating it once or twice. In order to get rid of dryness and elasticity of the skin, women may want to eat more gelatinous foods, such as Colla Corii Asini, pig skin and hoof tendons.

Shark's fin with meat and eggs, nutrition is easy to absorb

Nutritionist Hu Tingting analyzed the nutritional composition of shark's fin is mainly collagen and proline. If only take the protein for comparison, every 100 grams of dried shark's fin contains 83.5 grams of protein, which is much higher than a lot of food containing high protein, such as eggs (13.3 grams), lean meat (20.3 grams), prawns (18.6 grams), soybeans (34.2 grams). However, since shark's fin does not contain tryptophan, which is an incomplete protein, it is difficult for the human body to absorb it, and must be paired with meat, eggs, and shrimps and crabs, which contain more tryptophan, before its nutrients can be absorbed. Moreover, the cholesterol content of dried shark fin is high and the content of trace elements is not high. Therefore, there are claims that the nutritional value of shark's fin is similar to that of fish jelly. In addition, shark fins come from sharks, in order to protect the environment, it is best to eat less.
