Kelp is not suitable for everyone. Pay attention to the following three taboos: people with spleen and stomach deficiency and patients with hyperthyroidism cannot eat kelp, because the iodine content in kelp is relatively high, which will aggravate the disease; Pregnant women and nursing mothers should not eat more kelp, because the iodine contained in kelp will enter the body of the fetus (baby) with blood circulation or milk, causing thyroid dysfunction of the fetus (baby); Do not drink tea immediately after eating kelp, because drinking tea or eating sour food will affect the absorption of iron from kelp.
