bring down the blood pressure
Alginate in kelp belongs to potassium salt, which can remove excess sodium ions and adjust the balance of sodium and potassium. The sodium content in arteriole wall decreases, and the reactivity of smooth muscle to norepinephrine and other pressor substances weakens, which leads to the decrease of blood pressure. Laminaria japonica also contains laminin and histamine, which are effective antihypertensive components. Kelp also contains fucoidan and kelp polysaccharide, which has heparin-like activity and can prevent blood pressure increase and vascular embolism caused by blood viscosity.
Lowering blood lipid
Iodine in kelp can compensate hypothyroidism and prevent cholesterol accumulation and atherosclerosis in the body.
Kelp contains sulfated polysaccharides, which can enhance the activity of fatty acids in blood and reduce the concentration of blood lipids.
Sodium alginate contained in kelp can promote the excretion of bile acid from intestine, accelerate the conversion of cholesterol to bile acid, and reduce the concentration of cholesterol in blood.
Trace elements in kelp can also make the accumulation of fat in human body tend to subcutaneous and muscle tissues, and rarely accumulate in heart, blood vessels and mesentery. Therefore, eating kelp regularly can prevent cardiovascular diseases and lose weight.
Contains strong anticancer substances.
Kelp extract has obvious inhibitory effect on cancer cells and can prevent breast cancer. Kelp is also rich in polysaccharide dietary fiber, which can promote intestinal peristalsis and increase digestive gland secretion. It can not only help digestion and prevent constipation, but also reduce the retention and absorption of harmful substances in the intestine, which is conducive to the prevention of intestinal cancer.
Protect gastrointestinal tract and prevent enteritis.
Kelp polysaccharide contained in kelp, Undaria pinnatifida and other seaweeds is a kind of low molecular β-glucan, which can increase the number of lactic acid bacteria in the intestine and prevent ulcerative colitis. Lactic acid bacteria can also induce the differentiation of regulatory T cells that inhibit inflammation, increase the number of immune cells that inhibit inflammation, and have the function of preventing enteritis.
After eating kelp, alginic acid can form a gel protective film on the stomach wall, which has a good protective effect on gastrointestinal mucosa and can accelerate wound healing.
Inverse peristalsis
Sodium alginate and calcium salt in kelp are made into hemostatic agent according to a certain proportion, which has excellent hemostatic effect and can be widely used in various hemorrhagic diseases of human body.
Prolong life
Compared with the elderly who don't eat kelp, the average morbidity of the elderly who eat kelp for many years is 5% ~ 8% lower, and their average life expectancy is 4 ~ 8 years. Japanese monks have always lived a long life, and many people think that one of the important reasons is that they often eat kelp and burn tofu.
