Health care effect of soft-shelled turtle 1 health care effect of whole soft-shelled turtle
Turtle has the effects of nourishing yin and suppressing yang, softening and resolving hard mass, reducing swelling and resolving hard mass, nourishing yin and clearing away heat, calming liver and calming wind, softening and resolving hard mass and so on.
1. 1 Enhance immune function.
Studies have shown that turtle extract can inhibit the content of lipid peroxide (LPO) in rat liver (P
Anti-tumor effect of 1.2
The active substances extracted from soft-shelled turtle have obvious anti-tumor effect. The soft-shelled turtle extract has obvious inhibitory effect on solid tumor caused by sarcoma S 180 strain, solid tumor and ascites tumor caused by Ehrlich ascites carcinoma strain, and can prolong the life of tumor-bearing mice. Mice were inoculated with B 16 cells and FBL-3 cells respectively, and the survival time of mice bearing different tumors was observed by feeding soft-shelled turtle polysaccharide. The results showed that turtle polysaccharide could obviously prolong the average survival time of tumor-bearing mice and had anti-tumor effect.
Anti-aging effect of 1.3
By comparing the contents of lipid peroxide (LPO) in the liver and lipofuscin in the heart of rats in the experimental group and the control group, the results showed that
Turtle can prevent the production of LPO in animals, enhance the body's antioxidant capacity and delay aging. The study also showed that the nutritional components of Trionyx sinensis can significantly improve SOD activity and reduce LPO content, which has the effect of delaying aging. Turtle is rich in n-3 highly unsaturated fatty acids, which can prevent cardiovascular diseases. Trionyx sinensis polysaccharide can improve the hypoxia tolerance and antifreeze effect of mice, prolong the swimming time of mice, and has anti-fatigue effect. Studies have proved that soft-shelled turtle can prevent the decrease of bone density and bone strength, prevent the loss of minerals in bone and prevent the infection of virus A in the body. Turtle also has anti-stress effects, such as treating skin and mucosal trauma, promoting ulcer healing, and promoting tissue healing of scalded wounds in rats.
2. The health care function of turtle shell
Shen Nong's Classic of Materia Medica, Lin Yi's Special Collection, Records of Famous Doctors, Theory of Medicinal Properties, Clinical Guide of Medical Records, True Classic of Materia Medica, Seeking Truth in Materia Medica, etc. The medicinal value of turtle shell is described in detail. Carapax Trionycis has the functions of softening hard mass, resolving hard mass, clearing away heat and removing steaming, and can be used to treat yin deficiency, fever, bone fatigue, insufficient internal wind and amenorrhea.
1 Enhance immune function.
The polysaccharide of Trionyx sinensis can obviously increase the thymus index and spleen index of immunosuppressed mice. Increase the semi-hemolysis value (HC50) of immunosuppressed mice sensitized by sheep red blood cells; Improve the transformation function of T lymphocytes in S 180 tumor-bearing mice and enhance the cellular immune function; Enhance the scavenging effect of mouse mononuclear phagocyte system on Congo red; It can obviously resist the atrophy of immune organs in mice caused by immunosuppressants, increase the number of white blood cells in peripheral blood of irradiated mice, increase the survival time and 30-day survival rate, and improve immunity.
2 Anti-tumor
The anti-tumor effects of turtle shell mainly include: reducing tumor weight, tumor inhibition rate and tumor-to-body ratio; Inhibit the proliferation of cancer cells; Reduce mitotic index; Reduce the colony formation rate of cancer cells; Increase LDH activity in supernatant of cancer cells; Improve lymphocyte transformation function, enhance spleen cell proliferation and differentiation and NK cell activity; Inhibition of DNA synthesis in mouse S 180 tumor cells; Change the morphology of cancer cells. The effects of humoral immunity, cellular immunity and nonspecific immunity are also the reasons for its antitumor activity.
3 Anti-hepatic fibrosis
Studies have shown that turtle shell can increase the content of hydroxyproline (HYP) in liver tissue of mice poisoned by CCI, and significantly decrease the activity of serum alanine aminotransferase (SGPT), which indicates that turtle shell can prevent liver fibrosis in experimental rats.
4 Anti-fatigue and anti-hypoxia.
Taking serum urea nitrogen as an index of physical endurance, the worse the body's adaptability to load, the more serum urea nitrogen content. The results showed that the serum urea nitrogen in the experimental group was significantly lower than that in the control group (P < 0.05), and turtle shell could increase LDH activity, accelerate the elimination of excessive lactic acid in muscle, delay the occurrence of fatigue or accelerate the elimination of fatigue. Taking respiratory arrest as an index, the time of hypoxia death in mice was observed, which showed that turtle shell could increase the hypoxia tolerance of yin deficiency mice.
5 anti-mutation
Taking sister chromosome exchange (SCE) as an anti-mutagenic index, the SCE value increases with the presence of mutagens, but decreases or remains unchanged with the presence of mutagens. Carapax Trionycis can significantly reduce SCE value, that is, Carapax Trionycis has antimutagenic effect. In addition, turtle shell powder can increase bone mineral density, which is superior to calcium carbonate in apparent calcium absorption rate, femur bone mineral density and bone calcium content, and has certain therapeutic effect on osteoporosis. Can a turtle shell be made? Yin deficiency? The overall oxygen consumption of rats decreased, the pain threshold was prolonged, the heart rate was slowed down, and the water consumption, weight loss, blood sugar, serum total cholesterol, plasma and plasma CAMP levels of animals were improved. Yin deficiency? Disease, improve their swimming time and hypoxia tolerance. Carapax Trionycis can also increase the hemoglobin content of mice.
The nutritional value of soft-shelled turtle is rich in animal glue, keratin, copper, vitamin D and other nutrients, which can enhance the body's disease resistance and regulate human endocrine function, and is also a nourishing product to improve the quality of breast milk and enhance the immunity and intelligence of infants.
The flippers of soft-shelled turtle are called "tortoise plastron", which is a kind of precious Chinese medicine and has the effect of nourishing yin and reducing fire. Can be used for treating dizziness, dizziness, asthenic fever, night sweats, etc. It also has a good effect on intractable headache left by head trauma (such as neonatal head hematoma). Carapax et Plastrum Testudinis is a kind of high molecular collagen, which contains various amino acids needed by the skin and has the effects of skin care, beauty and fitness. Of course, tortoise plastron is a traditional Chinese medicine, and doctors should decide whether to use it according to the specific situation.
High collar can treat proctoptosis. Take the whole neck, bake it with slow fire, mash it, mix it evenly with hot vinegar, soak it in wet vinegar, wrap it tightly with gauze, and fumigate it with air for 3-5 times. Although turtles have a good effect on postpartum weakness and energy loss. However, pregnant women and postpartum constipation should not be eaten or appropriate.
1. Suitable for people with weak constitution, yin deficiency of liver and kidney, bone steaming strain and malnutrition; Suitable for tuberculosis and extrapulmonary tuberculosis with low fever; Suitable for people with chronic hepatitis, ascites due to liver cirrhosis, hepatosplenomegaly, diabetes, nephritis and edema; Suitable for all kinds of cancer patients and after radiotherapy and chemotherapy; Suitable for patients with Sjogren's syndrome; Suitable for patients with hyperlipidemia, arteriosclerosis, coronary heart disease and hypertension; Suitable for patients with hypoproteinemia; Suitable for beriberi patients;
Soft-shelled turtle is greasy, which leads to indigestion for a long time, so it is not suitable for people with loss of appetite, decreased digestive function, pregnant women or postpartum deficiency cold, spleen and stomach weakness and diarrhea; Loose stool people with chronic enteritis, chronic dysentery and chronic diarrhea should not eat; Eating hepatitis patients will increase the burden on the liver, and when it is serious, it will induce hepatic coma, so it should be eaten less; Eating it by pregnant women will affect fetal health; In addition, people who eat too much phlegm should eat carefully.
1. 1 protein and amino acids.
The protein content of soft-shelled turtle varies with its parts. According to experts' measurement, the turtle skirt contains 29% protein, 23% eggs and 0/8% fish/kloc, while the turtle liver contains the least protein, only 8%. It can be seen that the changing trend of protein content in various parts of soft-shelled turtle is: soft-shelled turtle skirt >; The protein content of Carassius auratus eggs >: Cyprinus carpio > Trionyx sinensis liver is also affected by the ecological conditions of culture. Comparing the nutritional components of skirt, muscle and liver tissue between bionic soft-shelled turtle and greenhouse soft-shelled turtle, it was found that the crude protein content of bionic soft-shelled turtle was significantly higher than that of greenhouse soft-shelled turtle.
In addition, experts also measured the protein content of the viscera extract of Trionyx sinensis as 46.5g/ 100g.
To evaluate the quality of food protein, besides its protein content, the types and composition of amino acids are also very important.
Study on nutritional value and health care efficacy of soft-shelled turtle: Basic acid content is not only high [(76.3? 2 1.5g)/ 100g], and the variety is complete, and the eight essential amino acids needed by the human body [(45.8? 8.7 g)/100 g] accounts for more than 60% of the total amino acids. Similar to the distribution law of protein content, the amino acid content in different parts of soft-shelled turtle is also different. The contents of total amino acids in fresh eggs, meat, blood and liver were 0.228 g/g, 0. 160 g/g, 0. 155 g/g and 0.15/g/g, respectively. In addition, the amino acid content of soft-shelled turtle is related to its sex and feeding conditions. The total amount of amino acids in muscle of female soft-shelled turtle (86.3g/100g) was slightly higher than that of male (83g/100g). The contents of essential amino acids and umami amino acids in bionic soft-shelled turtle muscle are higher than those in greenhouse soft-shelled turtle, and the taste is more delicious. Besides the edible parts of soft-shelled turtle, turtle shell also contains amino acids, among which proline content is the highest (0.270g/g), followed by glycine (0. 170g/g). Although the total amount of amino acids in bile is low, the content of taurine is extremely high.
1.2 fats and fatty acids
The fat content in different parts of soft-shelled turtle varies greatly. For example, the fat content of soft-shelled turtle is only 3.4%, while the fat content of fish eggs and liver is 18.2% and 25.7% respectively. As far as its fatty acid composition is concerned, turtle oil is highly unsaturated, and its monounsaturated fatty acids and polyunsaturated fatty acids account for 45.7% and 37% of the total fatty acids respectively, among which DHA and EPA account for 8.3% and 7.0% of the total fatty acids respectively, which is higher than that of ordinary fish. In addition, the viscera extract of soft-shelled turtle is also rich in unsaturated fatty acids (29.9%), and the content of polyunsaturated fatty acids is 17.6%. Turtle is rich in n-3 highly unsaturated fatty acids, and the content of n-3 highly unsaturated fatty acids in turtle can be used to evaluate the nutritional value of turtle, so turtle can be used as a new raw material to develop functional food rich in highly unsaturated fatty acids, which has high health care and nutritional value.
1.3 minerals and vitamins
Soft-shelled turtle contains a variety of minerals, including rich macroelements such as potassium, sodium, calcium, magnesium and phosphorus, and various trace elements necessary for human body such as iron, zinc, copper, manganese and chromium. The contents of potassium, sodium, zinc and copper in meat are basically the same as those in blood. Some elements in meat are higher than those in blood, such as calcium, magnesium, aluminum, manganese, barium, gill and lanthanum, which is about 100 times of that in blood, while some elements in blood are obviously higher than those in meat, such as iron. In addition, soft-shelled turtle is also rich in vitamins, such as the high content of VA in soft-shelled turtle liver, reaching 0.09g/g；/g; The contents of VB 1 and VB2 in soft-shelled turtle are the highest, with 100g reaching 0.9g and 0.5 1g respectively. The contents of VA and VD are also high, and 100g reaches 0. 15g and 0.0 15g respectively. To sum up, soft-shelled turtle contains a large number of essential minerals and vitamins, and its nutrients are beneficial to the normal metabolism and growth of human body.
1.4 polysaccharide
The polysaccharide contents in fish and eggs are basically the same, which are 4. 1 g and 4.9g/ 100g respectively, while the polysaccharide content in liver is relatively small, only1.4g.. Galactose and glucuronic acid are the main monosaccharides of soft-shelled turtle polysaccharide, and soft-shelled turtle polysaccharide contains galactosamine, glucosamine, mannose, galacturonic acid, galactose, glucose, glucuronic acid and pentose, among which galactose is the highest monosaccharide, accounting for about 0.3g/600, which may be one of the active factors or pharmacological active substances with good health care function in soft-shelled turtle.
Who can't eat soft-shelled turtle 1 Due to gastric mucosal edema, intestinal villi thickening and shortening, bile secretion disorder and other factors, the digestion and absorption function of hepatitis patients is greatly weakened. Turtle is rich in protein, which is not only difficult for patients to absorb after eating, but also increases the burden on the liver. In severe cases, there will be a large number of necrosis of hepatocytes, a sharp increase in serum bilirubin and an increase in plasma concentration, which will induce hepatic coma.
2, insomnia, pregnant women and postpartum diarrhea are also not suitable for consumption. Although it has the effect of nourishing yin and tonifying kidney, turtle tastes salty and cold, and has a strong effect of dredging collaterals and removing blood stasis, so it has some disadvantages of abortion, especially the abortion power of tortoise shell is stronger than that of nail fish.
3. People with weak gastrointestinal function and indigestion should be careful to eat. Especially those suffering from gastroenteritis, gastric ulcer, cholecystitis and other digestive system diseases. People with weak spleen and stomach should not eat more, otherwise they will often lose appetite, abdominal distension and even cause diarrhea.
Children should eat less soft-shelled turtle. Turtle is a high-protein tonic, and children's spleen and stomach are delicate. Eating it may lead to indigestion and increase the burden on the spleen and stomach, so eat less.
