Four Attentions to Kelp Eating

01. Kelp should not be immersed for a long time before eating. Generally speaking, soak for about 6 hours, because soaking time is too long, nutrients in kelp, such as water-soluble vitamins, inorganic salts, will also dissolve in water, nutritional value will be reduced. If kelp is as tough as boiled after soaking in water, it means it has deteriorated and can no longer be eaten. Chinese medicine believes that kelp cold, spleen and stomach deficiency cold people avoid eating.
02. Don't eat kelp as staple food. Kelp can't be used as staple food for a long time. This will lead to excessive iodine intake, which will also have an impact on health. In addition, kelp contains a certain amount of arsenic. Too much arsenic intake can cause poisoning. Therefore, before eating kelp, it should be rinsed with water to dissolve arsenic in water.
03. Don't drink tea immediately after eating kelp. Don't drink tea immediately after eating fruit. Don't drink tea immediately after eating kelp (tea contains tannic acid), and don't eat sour and astringent fruit immediately (sour and astringent fruit contains phytic acid). Because kelp is rich in iron, the above two foods will hinder the absorption of iron in the body.
04. Special people should eat kelp cautiously. Patients with hyperthyroidism should not eat kelp, because the iodine content in kelp is rich, it will aggravate the condition. Pregnant women and lactating mothers should not eat kelp more. This is because iodine in kelp can enter the fetus and infant with blood circulation, causing thyroid dysfunction.
