Benefits of sodium alginate dietary fiber to human body

　　Food fiber is a macromolecule with polysaccharide structure, which is the main component of seaweed cell wall and also distributed in the intercellular space. Red algae and brown algae are rich and varied in dietary fiber, and most of them are water-soluble.

　　The content and structure of fiber vary with the species of algae. The fiber composition of green algae is almost the same as that of terrestrial plants, mainly cellulose, but the red algae is watercress, carrageenan and cloth paste, and the brown algae is alginic acid, fucoidan and kelp sugar. Generally, the fiber content of seaweed is about 30 ~ 65% of the dry weight, which is much higher than the average content of beans, grains, vegetables and fruits.

　　What is the use of dietary fiber in human health care? Taking animal experiments as an example, adding alginic acid to feed can improve the symptoms of hyperlipidemia in mice and inhibit the increase of blood cholesterol content; Carrageenan and watercress can combine with cholesterol and regulate blood sugar.

　　Therefore, moderately increasing the intake of seaweed fiber can reduce blood pressure, blood cholesterol and blood sugar, which is helpful to the normal law of heart and blood vessels and prevent cancer.

　　In addition, seaweed food fiber expands after it enters the human gastrointestinal tract because of absorbing water, which is easy to cause satiety, avoid obesity caused by excessive food intake, and achieve weight loss and health care effects. In human body, dietary fiber can help digestion and promote waste excretion, avoid the growth of harmful bacteria in the body, and has the function of intestine regulation.
