Immunity is the body's own defense mechanism, and its function is to identify "self" and "alien" and exclude foreign bodies from foreign invasion, thus maintaining the balance and stability of the body's internal environment. When viruses, bacteria and other harmful substances enter the body, the human immune system will monitor, defend and adjust various functions, and establish a "defense line" to kill or inhibit pathogens and defend our bodies.
The physiological law of biological organism shows that with the increase of age, the immune function of human body is declining, and the incidence of infectious diseases and tumors is greatly increased. Besides innate immunity, immunity can also be obtained. This acquired immunity is called adaptive immunity, also called specific immunity or acquired immunity. Adaptive immunity can be improved through reasonable diet, exercise, sleep and emotional control. Among them, diet is one of the most important factors, because some nutrients in food can stimulate the immune system and enhance the immunity of the body.
With the development of science and technology, people's research on marine biological resources has been deepened, and the bioactive substances and biological functions of seaweed have been widely studied, among which fucoidan, especially fucoidan, has become a hot research topic in the world. Fucoidan sulfate is a sulfate-containing polysaccharide from brown algae. A large number of studies published so far show that fucoidan can activate our immune system.
In 2006, Professor Nakano Takahisa of Kitsato University discovered that fucoidan can enhance human immunity and specifically kill cancer cells by using patients' own immune system. Fucoidan can be recognized by immune cells after entering the intestine, producing signals to activate the immune system and activating NK cells, B cells and T cells. (Plant Medicine, July 2, 2006, 14 15. )。 In 2008, Professor Hong-Gujoo of Jeju National University in South Korea confirmed the immunostimulating effect of fucoidan on bone marrow-derived dendritic cells. Fucoidan has a strong activating effect on dendritic cells, which can enhance dendritic cells to secrete more cytokines, such as interleukin-12, tumor necrosis factor-α and so on. At the same time, the expression of dendritic cell surface activating molecule (CD54\CD86) also increased significantly (Immunology Letters, 2008, 1 15, 138- 143). ). In the same year, the research team of Professor Qu Xun from Qilu Hospital of Shandong University found that fucoidan can stimulate the maturation of human monocyte dendritic cells and promote monocyte dendritic cells to secrete a large number of cytokines interleukin-12 and tumor necrosis factor-α, which proved that fucoidan has a strong immune activation function (International Immunopharmacology, 2008, 8:1754-/kloc-0
As a health care aid for healthy people, it is recommended to take 0.5~ 1g fucoidan every day. If it is a patient, it is recommended that the total daily intake be 3~4g. Because of the accumulation of heavy metals in seaweed and the low content of fucoidan, it is not recommended that people obtain fucoidan by eating seaweed. It is more convenient, safer and more worry-free to take the extracted and purified fucoidan directly.
Yueming seaweed group was established in 1968, and has been deeply involved in the research and development of high-value seaweed active substances, with a number of patented technologies of fucoidan. As an enterprise approved to produce fucoidan food, Yueming Haizao Group has a fucoidan production line with an annual output of 65,438+00 tons. The fucoidan produced by this method has better flavor and taste, and the fucoidan content (purity) is higher, so it can be used in functional food, health food and other fields. At present, Yueming Seaweed Group has a variety of fucoidan products, which are committed to "disease prevention", giving play to the "homology of medicine and food" effect of fucoidan and protecting health.
