In addition to vitamins and trace elements, kelp also contains a lot of dietary fiber, especially soluble fiber. Dietary fiber refers to plant components that are not decomposed by digestive tract enzymes. It can play a role in human body through a variety of specific mechanisms, mainly including water absorption and swelling, increasing satiety, accelerating gastric emptying, lowering pH value of intestinal cavity, promoting bile acid metabolism, and lowering blood cholesterol.
Extended data:
You can't take kelp as the staple food for a long time, so you will consume too much iodine and have an impact on your health. Moreover, kelp contains a certain amount of arsenic, and excessive intake of arsenic will cause poisoning. Therefore, before eating kelp, wash it with water and let arsenic dissolve in water.
Don't soak kelp for a long time before eating, because the soaking time is too long, the nutrients in kelp, such as water-soluble vitamins and inorganic salts, will also dissolve in water, and the nutritional value will be reduced. If kelp is as tough as boiled after soaking in water, it means it has gone bad and can't be eaten any more. Traditional Chinese medicine believes that kelp is cold, and people with spleen and stomach deficiency are forbidden to eat.
Don't drink tea or eat sour fruit immediately after eating kelp, because kelp is rich in iron, and the above two foods will hinder the absorption of iron in the body.
