Porphyra is a general term for seaweed and can be eaten. Unlike most algae, laver is a multicellular organism visible to the naked eye. Generally, it lives on the seabed tens of meters away from the intertidal zone and is dark brown, red or purple. Porphyra gets its name because it is edible.
Porphyra has been recorded in China since before the Han Dynasty. It has always been regarded as one of the precious seafood, which is extremely delicious and deeply loved by people. As early as 65,438+0,400 years ago, it was mentioned in the Book of Qi Yaomin in the Northern Wei Dynasty that "all the mountains near the sea in Wudu are raw with laver", and it was also recorded in Compendium of Materia Medica that laver can cure heat and block the throat.
Porphyra, bred in the deep blue sea of the mother of life, absorbs the essence of the earth, the sun and the moon, and contains perfect protein, low fat, rich calcium and iodine, and various vitamins A, B 1, B2, C and cellulose. Taurine is also rich in content. It is outstanding among all algae. It is an ideal food to achieve balanced nutrition.
Nutritional Value of Porphyra Porphyra is rich in nutrition, with protein content exceeding that of kelp and containing more carotene and riboflavin. Every100g of dried laver contains protein 24-28g, fat 0.9g, carbohydrate 3 1-50/-50g, calcium 330mg, phosphorus 440mg, iron 32mg, carotene1.23mg, riboflavin 2.07mg and nicotinic acid 5./kloc. Isoleucine (1.4g) is the highest content of protein, iron, phosphorus, calcium, riboflavin and carotene in all kinds of vegetables, so laver is also called "nutritional treasure house".
Porphyra is not only delicious, but also nutritious, especially with high iodine content. Therefore, it was used in ancient times to treat the big neck disease caused by iodine deficiency, which is now called "goiter". Because laver has the function of softening and resolving hard mass. Therefore, it can also be eaten by other people with blood stasis.
Porphyra is rich in calcium and iron, which is not only an excellent food for treating anemia in women and children, but also can promote the growth and health care of bones and teeth in children and the elderly.
Porphyra is rich in choline, which can enhance memory.
Because it contains a certain amount of mannitol, it is a strong diuretic and can be used as an auxiliary food to treat edema.
1, iodine
People regard iodine as an "intellectual element" because it is closely related to the development of the brain. Porphyra enjoys a high reputation because it is rich in iodine. Its iodine content is 18000 μ g/kg (grain and vegetables are only 10 digits), so it is one of the best iodine-rich foods. Can be used for treating goiter caused by iodine deficiency. Porphyra has the function of softening and resolving hard mass, and is also useful for other blood clots.
Iodine can also stimulate the secretion of luteinizing hormone in the anterior pituitary (brain) and promote luteinization of follicles, thus reducing the level of estrogen, restoring the normal function of ovaries, correcting endocrine disorders, eliminating the pain caused by mammary gland hyperplasia and reducing hidden dangers of lesions.
vitamin
Porphyra is called "the treasure house of vitamins". Porphyra contains a variety of vitamins, and the content of B vitamins is not inferior to that of vegetables. The content of B vitamins in laver is very high, especially vitamin B 12, which hardly exists in terrestrial plants. In terms of dry matter, the content of vitamin B 12 is similar to that of fish, and the content of vitamin C is also very high. Vitamin B 12 has the functions of activating cranial nerves, preventing aging and memory decline, and improving depression.
iron
According to research, the occurrence of deafness and tinnitus is related to the lack of some trace elements, especially the lack of iron is easy to harden red blood cells and reduce the ability to transport oxygen, while the lack of nutrition supply in the ear will damage the function of auditory cells and lead to hearing loss. Therefore, iron supplementation is the first factor to prevent deafness and tinnitus. Iron deficiency, if you can't make enough red blood cells, you will suffer from "iron deficiency anemia". No matter what kind of anemia, it will make the brain hypoxic, especially affecting the intellectual development of babies.
Porphyra contains the most iron in daily food, with an iron content of 46.8 mg per100g. It is recommended to drink laver soup 2 to 3 times a week to ensure the iron content needed by the human body. It is best to add an egg to the soup, because the egg is beneficial to the absorption of iron. Foods containing more iron include shrimp skin, jellyfish skin, black sesame, day lily and so on. For people over 45 years old, the daily iron intake should be no less than12mg, and the iron content of the above foods is above12mg per100g. Therefore, it is very beneficial to arrange these iron-rich foods reasonably in three meals a day to prevent senile deafness and tinnitus.

Protein and amino acids
Bioactive substances in laver are very important to the life activities of plants. Generally, the protein content of edible laver is 24%-28%, which is much higher than that of ordinary vegetables, and there are many essential amino acids. Porphyra protein contains many neutral and acidic amino acids, such as alanine, aspartic acid, glutamic acid, glycine, proline and so on, which are characteristics that all terrestrial vegetables and plants do not have.
Whole grains are the staple food that must be eaten every day, but the plant protein contained in whole grains lacks lysine. Lysine is an essential amino acid. Without it, the utilization rate of protein in staple food will be greatly reduced. The lysine content of laver and seaweed is about 5 times that of rice, instant noodles, Fuqiang powder and dried noodles. If we put some laver when eating noodles, a bowl of laver soup when eating rice, and a bowl of laver wonton when eating big cakes, it will be easy to play a "protein complementary role" and the protein in the staple food will be upgraded.

Fatty acids and palmitic acid
Compared with terrestrial plants, the fat content of laver is relatively low, accounting for only 1%~2% of all nutrients, but the content of unsaturated fatty acid EPA which is beneficial to the development of nervous system accounts for 52%, and palmitic acid in saturated fatty acid accounts for the vast majority of laver fat, about 20%. The contents of onion acid and stearic acid in beans are less, accounting for 2% respectively; Unsaturated fats-linoleic acid, linolenic acid or octadecatetraenoic acid, which have a good health care effect on human body, contain a large amount of 10%-30%, and highly unsaturated fatty acids above C20 also contain a certain amount. Even better, the content of eicosapentaenoic acid in laver, which is known as "brain gold", is as high as 30%.
Inorganic substances and choline
Seawater is rich in inorganic components, and laver has the function of absorbing and storing inorganic substances in seawater. Because the inorganic matter in laver is extremely rich, it promotes bone formation and has health care function.
Laver is rich in choline, and eating laver often can improve memory loss.
magnesium
Coronary heart disease, hypertension, hyperlipidemia and diabetes often occur after middle age, which is related to the decrease of magnesium content in the body. The researchers found that the content of magnesium in the heart of patients who died of myocardial infarction and other diseases was much lower than that of normal people. If the human body lacks magnesium, it will also lead to tachycardia, arrhythmia, myocardial necrosis and calcification. Magnesium can activate many enzymes in the body, inhibit nerve excitation, maintain the stability of nucleic acid structure, and participate in protein synthesis, muscle contraction and body temperature regulation. In addition, the lack of magnesium will also affect people's mood and make people nervous easily. Porphyra yezoensis has the highest magnesium content, with 460 mg per 100 g, which is known as the "treasure house of magnesium".
mannitol
Porphyra contains a certain amount of mannitol, which is a strong diuretic, has the effect of treating edema, and can also assist in the treatment of other diseases of stagnation and agglomeration.
potassium
The new concept of health advocates "speaking lightly". Because "high sodium" is harmful to cardiovascular health, potassium is compared to "the protector" of cardiovascular health, so a proper amount of potassium is a necessary condition to maintain the normal work of myocardium, blood pressure and environmental acid-base balance.

Efficacy and function of laver (I) Efficacy of laver
Porphyra is sweet, cold and non-toxic, and can be used as medicine. It has the effects of resolving phlegm, softening hardness, clearing heat and promoting diuresis, tonifying kidney and nourishing heart. According to "Living with the Heart", laver nourishes the blood and the heart, eliminates annoyance and heat, cures insomnia, benefits the throat, eliminates beriberi swelling and pain, governs diarrhea, wakes up and stimulates appetite. Modern medicine also has a high evaluation of the efficacy of laver. Eating more laver has a good effect on preventing and treating gastric ulcer and menopausal symptoms of women, delaying aging, preventing anemia, preventing skin dandruff and itching, preventing tooth decay, treating night blindness, lowering blood pressure, lowering blood fat and cholesterol.
(B) the role of laver
Effect on immune function
Porphyra has obvious functions of enhancing cellular immunity and humoral immunity, thus promoting the transformation of lymphocytes. In addition, the polysaccharide in laver can also enhance the phagocytic function of macrophages, increase the weight of immune organs, resist spleen atrophy caused by cyclophosphamide, and have obvious agglutination effect on red blood cells.
Effects on the heart
Porphyra can slow down the heart rate and enhance the myocardial contractility. Moreover, the content of magnesium in laver is relatively high, with 460mg of magnesium per 100g, which is known as the "treasure house of magnesium" and is very beneficial to regulating the heart.
Effect on blood system
Porphyra is rich in iron and vitamin B 12, which is an essential nutrient for hematopoiesis.
Moreover, scientific research shows that laver has obvious anticoagulant effect, which can significantly reduce hemorheological indexes such as whole blood viscosity, plasma viscosity, whole blood reduced viscosity and hematocrit. However, it can improve erythrocyte sedimentation rate, significantly prolong the time of specific thrombosis and fibrin thrombosis, shorten the length of thrombus and reduce the wet weight and dry weight of thrombus, but it has no obvious effect on the water content of thrombus. Therefore, laver can promote the normal operation of blood system and protect the safe operation of blood system.
Hypolipidemic effect
Laver can prevent the formation of hypercholesterolemia. Porphyra can significantly reduce the outbreak rate of hyperlipidemia caused by eating high fat and cholesterol. Eating appropriate amount of laver can also reduce the content of total cholesterol in serum.
Chinese medicine believes that laver has expectorant, dehumidifying and diuretic effects; It is delicious and easy to be absorbed, and is suitable for elderly patients with hyperlipidemia.
Antitumor effect
Scientific research shows that laver can inhibit sarcoma with an inhibition rate of 47.55%. The inhibitory rate of effective components of laver on Ehrlich cancer is 53.2%, which is helpful for the prevention and treatment of brain tumor, breast cancer, thyroid cancer, malignant lymphoma and other tumors.
Anti-aging effect
Scientific experiments show that laver can significantly prolong the average life span of Drosophila melanogaster, increase its flying percentage and significantly reduce the lipofuscin content of hatched Drosophila melanogaster.
Porphyra is called "longevity vegetable". Every 100g of dried laver contains 25-30g of protein, which is equivalent to soybean, and is also rich in vitamins and other nutrients. Protein and other nutrients in laver are easy to digest and absorb, which is very suitable for the elderly with decreased digestive function and has the effect of prolonging life for the elderly.
radioresistance
Porphyra has a protective effect on radiation exposure.
Anti-leukopenia effect
Porphyra has obvious antagonistic effect on leukopenia caused by cyclophosphamide, but has no obvious effect on normal white blood cell count.
Hypoglycemic effect
Scientific research shows that laver can significantly reduce normal fasting blood sugar, and diabetic patients can eat laver before meals to reduce blood sugar.
Anti-liver injury effect
Purple has obvious antagonistic effect on the increase of serum alanine aminotransferase in liver injury. Japanese scientific research shows that dark food generally has a greater effect on strengthening the spleen and liver.
Weight loss effect
Porphyra is suitable for obese women to eat regularly and can achieve the effect of slimming and shaping. Porphyra is rich in dietary fiber and low in calories. In addition, it has the effect of clearing heat and diuresis, and the weight loss effect will be more obvious.
Relieve constipation
Rich in unusually soft crude fiber is also one of the outstanding advantages of laver, which contains 4.8 grams of crude fiber per 100 gram of dry product. Crude fiber is a conscientious "scavenger" in human intestine, and the crude fiber of laver is difficult to be digested by human gastrointestinal tract. After eating, it can increase intestinal peristalsis and smooth stool, which is beneficial to the excretion of harmful substances in the body. When the soup is drunk, it tastes delicious and can be eaten frequently, which can remove mucus, gas accumulation and corruption accumulated in intestinal cavity, maintain intestinal health and prevent colorectal cancer.
The role of AIDS prevention and treatment
There is a certain chance that the polysaccharide in laver can combine with HIV (human acquired immunodeficiency virus) to inactivate it, thus inhibiting virus replication. Therefore, laver can prevent and treat AIDS to some extent.
Enhance memory function
Ribonucleic acid is the main substance to maintain brain memory. Porphyra is rich in trace element magnesium, which can promote brain to absorb ribonucleic acid. At the same time, Purple Pole is also rich in choline, which is of great benefit to protecting the brain and improving memory.
Eye protection and moisturizing effect
The content of vitamin A in laver is about 67 times that of milk, which can maintain normal vision and prevent eye dryness and fatigue. The content of vitamin C in laver is about 70 times that of cabbage, which is of great significance to skin bodybuilding.
How to eat laver (1) How to eat laver
People in China have been eating laver for more than 1000 years. According to the Compendium of Materia Medica written by Li Shizhen, the drug king of Ming Dynasty, laver can "cure the disease of heat scabies".

(2) How to select laver
The color is purplish red, no sediment, no impurities and dry. On the contrary, the quality is poor. If the laver soaked in cold water is blue-purple, it means that the dish has been contaminated by toxic substances before drying and packaging. This kind of laver is harmful to human body and can't be eaten.
(3) Preservation method of laver
Porphyra is seafood for 3-6 months, which is easy to regain moisture and deteriorate. It should be packed in black food bags, placed in a low-temperature dry place, or placed in a refrigerator to maintain its taste and nutrition.
Porphyra is suitable for the general population and everyone should eat it. It is especially suitable for patients with goiter, edema, chronic bronchitis, cough, swelling and pain, gonorrhea, beriberi, hypertension, early lung disease, cardiovascular disease, various lumps and hyperplasia.
Some people should not eat more. For example, people with poor digestive function and vegetarian spleen deficiency eat less, and laver can easily lead to diarrhea in such people; Abdominal pain loose stool fasted; It is not suitable for people with spleen and stomach deficiency and cold.
This food is similar to laver. Persimmon laver is rich in calcium ions. Eating with persimmon containing too much tannic acid will form insoluble conjugate, which is easy to produce stones. Avoid eating together. Quail laver is a kind of food matched with laver, which can tonify kidney, nourish blood and lower blood pressure, and is suitable for hypertensive patients with yin deficiency of liver and kidney. Honey laver laver can clear away heat and resolve phlegm, and honey can relieve cough and moisten the lungs. Moderate consumption, both are beneficial to the health of the lungs and bronchi. Porphyra is rich in folic acid, iron and vitamin B6. It can be used together with squid rich in protein and zinc to beautify and strengthen the body. Tofu, laver and laver are suitable for eating with tofu. Saponin in tofu can cause iodine deficiency in the body, while laver contains more iodine, which can induce goiter. Eating together can balance the iodine in the body. Broccoli and laver packages contain a small amount of goiter-causing substances, so broccoli can be neutralized by eating iodine-rich foods such as laver. White radish laver white radish can relieve phlegm and cough and promote digestion; Porphyra has the function of clearing away heat and resolving phlegm. The combination of the two can clear lung heat and treat cough.
