While wakame has a high economic value and medicinal value, not only rich in protein, vitamins and minerals, but also contains fucoidan, mannitol, fucoidan, high unsaturated fatty acids, fucoidan, organic iodine, steroids, dietary fiber, and other unique physiological functions of the active ingredients. It has various physiological activities such as hypolipidemic, hypotensive, immunomodulatory, anti-mutagenic, anti-tumor, etc.[2] . It has a variety of pharmacological effects, and has a good effect in antiviral, anti-tumor, blood pressure, weight loss, and cardiovascular and cerebrovascular disease treatment.

Wakame contains a variety of nutrients, according to the preliminary analysis of each hundred grams of dried products containing 11.6g of crude protein, 0.32g of refined fat content, 37.81g of sugar, ash 18.93g, also contains a variety of vitamins, crude protein content is higher than kelp, the flavor of which is more than kelp. Wakame is not only a kind of edible economic brown algae, but also can be used as a comprehensive utilization of raw materials for extraction of fucoidan.

At the same time is known as smart food, beauty dishes, health dishes, green sea cucumber wakame, is a natural treasure trove of trace elements and minerals, containing more than a dozen kinds of essential amino acids, calcium, iodine, zinc, selenium, folic acid and vitamins A, B, C and other minerals. The calcium content of wakame is 10 times that of milk, the king of calcium, and the zinc content is 3 times that of beef, the best zinc supplement. 500 grams of wakame contains iron equal to 21 pounds of spinach, vitamin C equal to 1.5 pounds of carrots, and protein equal to 1.5 sea cucumbers. Sea cucumber. Its iodine content is also more than kelp, plus rich in amino acids, crude fiber and other trace elements, children's bones, intellectual development is extremely beneficial. Wakame also features high nutrition and low calories, making it easy to achieve weight loss, clean the intestines, protect the skin, and slow down the aging process, making it a favorite dish for many women. One of the main reasons why Japan is recognized as a longevity country is that wakame is on the table every day. Wakame has become Japan, South Korea, children and students nutritional diet of essential dishes.

Japan has a long history of wakame cultivation and is a major consumer of wakame, and is a world leader in wakame nutrition and its relationship to human health. Mr. Kazutoshi Nishizawa, a famous Japanese expert in algal biochemistry, has been engaged in the research of nutrition, pharmacology and relationship with human health of seaweeds for many years, and his book "Undaria pinnatifida, the king of seaweeds" elaborates the nutritional and medicinal values of undaria pinnatifida through a large number of investigation results and experimental data, especially in the prevention and treatment of High blood pressure, adult diseases and other aspects of the special efficacy of the scientific discussion, and listed the scientific wakame consumption methods, is a collection of wakame basic knowledge, nutritional value, medicinal effects and its mechanism of introduction as one of the good book.

The Japanese have been consuming seaweed since B.C.E. This is amply confirmed by the excavation of the remains of shell mounds that have been unearthed. In addition, Wakame Shrine in Kitakyushu City and Sumiyoshi Shrine in Shimonoseki City, across the river from Kitakyushu City, still maintain the tradition that in the early morning of Spring Festival every year, the presiding officer of the shrine steps into the sea to hold a ceremony for harvesting wakame and enshrines the harvested wakame in front of the shrine to announce the beginning of the wakame harvesting season.

Mineral-containing human beings and animals, despite some differences, depend on the three main nutrients they take in from food, namely sugar, fat and protein, for their energy to survive. But is it true that these three nutrients alone are sufficient for human survival? In fact, animals cannot survive if they rely solely on these three nutrients. The reason is that in the body for the use of nutrients to carry out the process of life-sustaining activities, need to carry out a variety of chemical reactions, in order to make this chemical reaction can be carried out effectively, but also need a very small amount of special substances, that is, the participation of micronutrients, and these micronutrients mainly include vitamins and minerals.

As far as vitamins are concerned, since their discovery in 1912, their research utilization has made rapid progress in the first half of the 20th century. Symptoms of vitamin deficiencies and their mechanism of action in the body are well understood. However, in the study of minerals, even though they were discovered earlier than vitamins, there has not been much progress in their research due to the fact that they have not attracted much attention for a long time. In our daily life, what we know is only the relationship between iron and greed, iodine and thyroid dysfunction, calcium and bones and teeth and other knowledge, as for the role of various minerals, the specific human body in the end what minerals are needed, the number of a day how much is not very well understood. Through research, it has been found that there is a big difference between the mineral content in normal children and children with congenital anomalies, and it has also been found that a certain mineral can prevent arteriosclerosis, and the lack of which can lead to an increase in the incidence of breast cancer, which has made people pay attention to the importance of minerals. In other words, minerals form the skeleton of human life, and mineral deficiencies are an important cause of abnormalities and diseases in the human body. Under these circumstances, the United States, where research on mineral nutritional elements is much ahead of Japan, took the lead in proposing the concept of the human body's encouraged daily intake (RDA) of minerals. Americans are very much ahead of their time in their awareness of the fact that the occurrence of diseases is closely related to daily dietary life, and at the same time, they have a high level of research on cancer-preventing foods and vitamins. Therefore, as one of the important parts of the above research, just as the study of how much vitamin intake is actually needed in a day, a specific number has been proposed for minerals, which is the encouraged intake (RDA).

But in reality, micronutrient intake still shows a tendency to decrease, and anemia is a good example. According to the survey results, one out of every three women shows a tendency to anemia, most of which is iron-deficiency anemia, and insufficient intake of iron is the main cause of the disease. Eating less than the normal diet due to improved living standards, changes in the chemical composition of the food itself due to greenhouse cultivation, and the consumption of large quantities of processed products, such as convenience foods, are important reasons for the inadequate intake of minerals by modern people.

What kind of food should be consumed in daily life to ensure adequate intake of minerals? The first recommendation should be seaweed such as wakame. Seaweeds are often compared to "sea vegetables," and the biggest difference between them and plants on land is that their bodies absorb a lot of nutrients from seawater, and the ocean is the richest treasure trove of minerals. Therefore, with rich mineral nutrition cultivated wakame, for modern people is the most ideal source of mineral supplementation.

When it comes to the anti-cancer effects of wakame, I would like to emphasize the anti-cancer effects of Vitamin A here. We have known for a long time that if you are deficient in vitamin A, you are prone to night blindness. For example, when we first enter a movie theater, initially because of the darkness can not see anything, but after a while, the eyes will gradually adapt to be able to find a seat, which in physiology is called light and dark compliance. Vitamin A is indispensable for this light/dark adaptation. Vitamin A has been emphasized as a vitamin with anti-cancer properties. Until now, we only knew that vitamin A is indispensable for the normal division and maturation of skin and mucous membrane cells. If you are deficient in vitamin A, your skin will become as rough and ugly as shark skin. This is due to the abnormal phenomenon that occurs when the cells divided in the stroma layer of the skin gradually mature and age, and are transformed into the stratum corneum that covers the skin surface (also called keratinization of the skin). Experiments have shown that vitamin A not only maintains the normal division of cells, but also has the function of transforming the pre-cancerous state of cells into a normal state, which has attracted a great deal of attention. However, it is regrettable that the human body and can not be utilized in large quantities of vitamin A, because vitamin A belongs to the fat-soluble vitamins, only soluble in fats and oils, insoluble in water, and therefore can not be like other water-soluble vitamins that can be excreted with the urine, but the accumulation of the human body. If ingested in large quantities every day, it is easy to suffer from cerebral hyperpressurization, showing headaches, nausea, vomiting and other after-effects. In order to effectively utilize the benefits of vitamin A and to reduce its side effects, research on improved forms of vitamin A is being conducted in a variety of ways, but has not yet been successful. Therefore, in order to effectively utilize the anticancer effects of vitamin A, the best way at present is to make up for its deficiencies by using food, such as consuming an appropriate amount of animal liver, eel and other vitamin A-rich foods. However, such animal foods are more difficult to eat, and daily consumption of large quantities does not completely exclude the possibility of suffering from vitamin A sequelae. One of the best methods available is to get plenty of carotenoids from vegetables on a daily basis. Carotene is also known as a factory for the production of vitamin A. Once in the body, carotene is immediately broken down and 1/3 of it is converted to vitamin A. Although the conversion rate of vitamin A may be slightly lower, there is no need to worry about the after-effects of excessive intake of vitamin A. In addition, some experts have reported the possibility of postvitaminosis A syndrome in animal foods, as well as in animal products. In addition, some experts have reported that carotenoids not only break down to form vitamin A to prevent cancer, but also have a good effect on preventing cancer itself. It is well known that carotenoids are usually found in large quantities in green and yellow vegetables such as spinach, but the content of carotenoids in wakame is also quite high. It is determined that the content of carotene in every 100 grams of raw spinach is 3100 mg, while the content of carotene in every 100 grams of raw wakame is 1400 mg, and the content of carotene in 100 grams of dried wakame is as high as 3300 mg, which is by no means inferior to that of spinach. Therefore, wakame can get enough carotenoids when eaten together with yellow-green vegetables. In addition, carotenoids are in the same group as vitamin A, which is soluble in fats and oils, so if wakame is eaten with fats and oils, the absorption rate can be increased by almost three times. The utilization of carotenoids is greatly enhanced when wakame salad is topped with salad oil and dressing or lightly sautéed in oil.

Food fiber has the special function of adsorbing cholesterol and removing it from the body, and it will be further strengthened if beans, vegetables, and mushrooms, which are rich in plant fiber, are mixed together and consumed. Soybeans contain a lot of proteins that can strengthen blood vessels, but these proteins can prevent the effective absorption of iodine, which is a necessary raw material for the synthesis of thyroid hormones. Therefore, if you consume wakame, which is rich in iodine, you will receive a good iodine supplementation effect.

In addition, some of the body color blue fish body, containing unsaturated fatty acids to prevent thrombosis, seawater in the body of fish and shellfish contain a large number of minerals and reduce blood pressure effective substances. If these fish and shellfish and wakame are consumed together, the medicinal effect of wakame can be greatly improved.
