Nori is a red algae that grows on shallow rocky reefs in the sea and has a purple-red, greenish-purple and blackish-purple color, but when dried, it is purple. This purple sea plant is algae, but can be eaten as a dish, so the name seaweed.

seaweed is not only delicious, but also nutritious, especially high iodine content, so in ancient times it was used to treat iodine deficiency caused by the neck disease, which is now called "goiter". Since seaweed has the function of softening and dispersing knots, it can also be eaten by those who have other lumps. Nori is rich in choline, which is known to enhance memory. Because it contains a certain amount of mannitol, so it is a strong diuretic, can be used as an auxiliary food for the treatment of edema. The seaweed is rich in calcium and iron, not only is the treatment of anemia in women and children of good food, but also can promote the children and the elderly bones, teeth growth and health care.

Seaweed is suitable for all people except those who suffer from abdominal pain and loose stools. It is also suitable for patients with edema, athlete's foot, early stage of lung disease, goiter, cardiovascular disease and all kinds of lumps and growths.

Note: In order to remove pollution, toxins, should be soaked in water before use, and change the water once or twice. Gastrointestinal digestion should be eaten sparingly; abdominal pain and loose stools should not be eaten.

In fact, seaweed and nori are the same thing. There are two main types of seaweed we usually eat: the northern ones are mostly spotted seaweed, and the southern ones are mostly altar seaweed. The seaweed is processed with the striped seaweed.

Seaweed nutrition is very high, because it grows in the sea on the rocks, fully absorbed the essence of the sea, protein ah, minerals and vitamins are rich in content, including carotene, riboflavin, vitamin A, B content is particularly high. It also contains a lot of essential minerals such as iron and calcium, so it's not bad, right? What's even better is that seaweed has very little fat in it, so eating more of it can improve microcirculation and reduce the incidence of cancer and cardiovascular disease.

The seaweed we eat is mostly dried and processed, can the nutrition inside be preserved? Dried seaweed is not too high in calories, and it is a good snack because it is good for iodine supplementation. But if you have high blood pressure, do not eat more, because the dried seaweed salt and monosodium glutamate content is very high, eat remember to drink more water

Kelp belongs to the brown algae, kelp plants. It is also known as kombu, kelp cabbage, and river cabbage.

Botanical form: the algae body is brown, long banded, leathery, generally 2-6 centimeters long, 20-30 centimeters wide. The algal body is clearly divided into the anchoring apparatus, stalk and blade. The fixator is pseudo-root-like, the stalk is stout and cylindrical, and the upper part of the stalk is a broad, long, strap-shaped blade. In the center of the blade there are two parallel shallow grooves, in the middle of which is the midrib, 2-5 mm thick, and the two edges of the midrib are thin and corrugated. It is also an alga, but the root-like part is just a rhizome that serves as a cement, and the leaf-like part is called a phyllode.

[Origin, season] China's Liaoning, Shandong, Jiangsu, Zhejiang, Fujian and the northern coast of Guangdong Province are cultured, wild kelp in the low-tide line of the depth of 2-3 meters on the rocks are. Due to the impact of the difference in temperature from north to south, light and other factors, so that the growth of kelp maturity early and late, in the same sea area or the same seedling rope on the kelp, the maturity of its successive, so the harvest period from the middle of May extended to early July.

[Economic value] kelp is a very high nutritional value of vegetables, per 100 grams of dried kelp contains: crude protein 8.2 grams, 0.1 grams of fat, sugar 57 grams of crude fiber 9.8 grams of inorganic salts 12.9 grams of calcium 2.25 grams of iron 0.15 grams of carotenoids 0.57 milligrams of thiamine (Vitamin B1) 0.69 milligrams of riboflavin (Vitamin B2) 0.5 milligrams of carotenoids 0.57 mg of thiamine (Vitamin B1) 0.69 milligrams of riboflavin (Vitamin B2) 0.36 milligrams of niacin. 36 milligrams, 16 milligrams of nicotinic acid, can issue 262 dry calories. Compared with spinach, rape, in addition to vitamin C, its crude protein, sugar, calcium, iron content are several times higher, dozens of times. Kelp is a kind of seaweed with high iodine content. Cultured kelp generally contains iodine 3 ~ 5% 0, up to 7 ~ 10 flood. The iodine and fucoidan extracted from it are widely used in medicine, food and chemical industry. Iodine is one of the necessary elements of the human body, iodine deficiency will suffer from enlarged thyroid line, eat more kelp can prevent and cure this disease. It can also prevent arteriosclerosis, reduce cholesterol and lipid accumulation.

Sodium fucoidan in kelp has the effect of preventing leukemia and bone pain; arterial hemorrhage also has the effect of hemostasis, oral can reduce the absorption of radioactive elements strontium-90 in the intestinal tract. Sodium fucoidan has antihypertensive effect. Kelp starch has the effect of lowering blood lipids. In recent years, an extract of kelp has been found to have anticancer effects. Kelp mannitol is effective in the treatment of acute renal failure, cerebral edema, encephalitis B and acute glaucoma. It should not be consumed by people with cold spleen and stomach.
