Modern research shows that kelp contains carotene, B vitamins, and calcium, iron and other essential nutrients for the human body; kelp contains a variety of pharmacological effects Functional factors such as kelp starch (fucoidan), alginic acid ( fucoic acid), konbu polysaccharide, alginin, fucoidan, konbumin, and the like.

Kelp cannot be soaked for a long time: Do not soak for a long time before eating kelp. Generally, it should be immersed for about 6 hours. Because the immersion time is too long, nutrients in the kelp, such as water-soluble vitamins and inorganic salts, will also dissolve in water, and the nutritional value will decrease. If the kelp has no toughness after being soaked in water, it means that it has deteriorated and can no longer be eaten. Chinese medicine believes that those with kelp coldness and spleen and stomach deficiency should not eat.

Don t eat kelp as a staple food: Do not use kelp as a staple food for a long time. This will consume too much iodine and will affect your health. Furthermore, kelp contains a certain amount of arsenic, and excessive intake of arsenic can cause poisoning. Therefore, before eating kelp, it should be rinsed with water to dissolve arsenic in water.

Don t drink tea and fruit immediately after eating kelp: Don t drink tea immediately after eating kelp (tea contains tannic acid), and don t eat sour fruits immediately (acid fruits contain plant acids). Because kelp is rich in iron, these two foods will hinder the absorption of iron in the body.

Special people eat kelp carefully: Patients with hyperthyroidism should not eat kelp, because the iodine content in kelp is richer, which will aggravate the disease; pregnant women and nursing mothers should not eat kelp. This is because the iodine in the kelp can enter the fetus and infant with the blood circulation, causing thyroid dysfunction.
