It can be eaten or made into traditional Chinese medicine, so the seaweed is also Known as the "God of the Immortal." Seaweed contains a variety of essential nutrients. Its protein content is 9 times that of fresh mushrooms, which is higher than that of ordinary vegetables. Therefore, seaweed enjoys the reputation of “treasure treasureâ€. It is determined that each 100g of seaweed contains 28.2g of protein, 16.9g of carbohydrate, 27.3g of dietary fiber, 2420g of carotene, 4.3g of vitamin A, 216mg of cholesterol, 2mg of vitamin C2, 1.82mg of vitamin E, 0.44mg of vitamin B1. , fat 3.9g, potassium 1640 mg, calcium 422 mg, sodium 365.6 mg, iodine 1800 micrograms, magnesium 105 mg, phosphorus 350 mg, iron 46.8 mg, niacin 7.3 mg, magnesium 105 mg, selenium 7.22 micrograms, zinc 2.3 mg, Copper 1.68 mg.
The efficacy and function of seaweed
Detoxification and anticancer
A large amount of dietary fiber in seaweed accounts for about 1/3 of the total weight. It can not be absorbed and digested by the intestines. It will stimulate the intestinal tract to accelerate the peristalsis, swell and absorb harmful substances in the intestinal tract, and soften the hard stools. Helps prevent constipation and bowel cancer. In addition, dietary fiber can also proliferate beneficial bacteria in the intestines, help regulate intestinal flora balance and maintain intestinal health.
Prevent thyroid enlargement
The amount of iodine in seaweed is especially high. Frequently eating seaweed can be used to prevent thyroid enlargement caused by iodine deficiency.
Prevention of cardiovascular disease
The content of trace elements such as calcium, magnesium, iodine, phosphorus and potassium in seaweed is abundant. Experiments have shown that magnesium can prevent calcification of soft tissues in the body. Phosphorus can soften blood vessels. Potassium is the "protective god" of cardiovascular health. Regular consumption of seaweed is very beneficial for the prevention and treatment of cardiovascular and cerebrovascular diseases. In addition, dietary fiber in laver can reduce the absorption rate of cholesterol and promote the excretion of cholesterol, thereby lowering the level of cholesterol in the body and blood, and helping to prevent arteriosclerosis and coronary heart disease.
Calcium supplementation
When it comes to calcium supplementation, people first think of milk and bones, but in fact, the calcium content of seaweed is also very high. Every 100g of seaweed contains about 422 mg of calcium. Regular consumption of seaweed can also improve immunity.
Supplemental protein
The protein content of laver is much higher than that of common vegetables, and it is comparable to soybeans, so it is also called "sea bean".
Puzzle brain
Seaweed contains choline, calcium, iron and eicosapentaenoic acid, which is likened to "brain gold", which is very beneficial for protecting the brain and improving memory.
hypotensive
Seaweed is rich in potassium, which promotes the excretion of sodium. Studies have found that people who consume more sodium in their diet have lower blood pressure, so eating seaweed can prevent high blood pressure caused by high sodium.
Precautions for eating seaweed
The World Health Organization gives the average intake of iodine tolerance for normal healthy adults to 1100 mg/day, while the recommended intake of adult iodine recommended by the Chinese Nutrition Society is 120 μg/day, which is recommended not to exceed 600 μg/day. The iodine content in seaweed is very high, and each 100g of seaweed contains 1800 micrograms of iodine, so excessive intake of seaweed may cause hyperthyroidism.
