Marine vegetables are seaweed, such as kelp, seaweed, moss strips, Undaria pinnatifida and Eucheuma. China is rich in seaweed resources, and about 100 species are of economic value. Seaweed contains essential protein, fat, carbohydrates, vitamins and minerals, and its nutritional value is much higher than that of terrestrial vegetables. Because algae convert various inorganic substances in the ocean into organic substances under photosynthesis, there are some compounds in algae that are not found in terrestrial vegetables.

One is to lower blood pressure. Alginic acid is contained in brown algae such as kelp, and experts have found that alginic acid has obvious antihypertensive effect. Some people use dried kelp roots to treat hypertension. Of the 158 people who received treatment, 86 were effective, and the blood lipid of the patients also decreased. Cholesterol decreased by 58% and triglyceride decreased by 50.3%. The sugar content in seaweed such as kelp and laver is as high as 30% ~ 57%. It is found that the sugar in seaweed not only provides energy, but also contains fucoidan, which is a unique mucus component of seaweed and not found in terrestrial vegetables. Fucoidan has the activity of heparin, which can prevent the agglutination of animal red blood cells and prevent the increase of blood pressure caused by the increase of blood viscosity.

The second is to prevent stroke, cerebral thrombosis and cerebral hemorrhage and reduce their mortality and disability rate. Eating seaweed will greatly reduce the incidence of stroke. Seaweed contains a certain amount of essential fatty acids such as linoleic acid and linolenic acid, many of which are eicosapentaenoic acid. Eicosapentaenoic acid is a highly unsaturated fatty acid, which can prevent thrombosis. According to laboratory analysis, almost all seaweeds contain eicosapentaenoic acid, some of which account for 15% ~ 20% of fatty acids. Fucoidan starch sulfate extracted from fucoidan (starch) has the effects of lowering cholesterol, inhibiting lipid accumulation and cerebrovascular sclerosis.

The third is to protect the heart. Seaweed is rich in selenium besides polysaccharides and fatty acids which have protective effects on cardiovascular system. German scientists found that selenium deficiency is one of the causes of cardiovascular diseases. From the investigation of patients, they found that the selenium content in patients with coronary atherosclerosis and myocardial infarction is much lower than that in healthy people, and the number of people living in low-selenium areas who died of heart disease is three times higher than that living in selenium-rich areas. American scientists found that the number of people who died of heart disease in Colorado, which has the habit of eating selenium-containing seaweed, is only 1/5 of that in Washington State.

The fourth is anti-tumor. Middle-aged and elderly people who often eat laver rarely suffer from cancer. Japanese scientists have confirmed that kelp and brown algae in Japan's offshore waters have the effect of inhibiting tumors. The low incidence of breast cancer among Japanese women is related to their habit of eating seaweed. Some people use 10 species of edible algae from the Sea of Japan for anti-tumor experiments. The results show that six kinds of edible algae have anti-leukemia effect, and the main anti-tumor component is alginate. Seaweed also contains more water-soluble cellulose, which plays an obvious role in preventing constipation, thus reducing the excessive accumulation of harmful substances in the human body. Eating seaweed is an alkaline food. Eating alkaline food often helps to improve the acidic constitution of modern people and enhance their immune function. These can greatly enhance the anti-cancer ability of the human body. Selenium rich in seaweed can also block the metabolism of cancer cells and inhibit the division and growth of cancer cells.

The influence of "marine vegetables" on human health is not only these, but also has a good preventive and therapeutic effect on many patients who often occur in modern people. In view of its special function and abundant seaweed resources in China, we might as well put more "marine vegetables" on our table.
