kelp is not only the ideal iodine supplement for pregnant women, but also a good food for promoting brain development.

, however, the content of arsenic in kelp is also high, reaching 35-50 mg / kg, which is caused by seawater pollution. Arsenic and arsenic compounds are all toxic, the most toxic is trivalent arsenic (such as arsenic), while the toxicity of trivalent arsenic is small, but it can still be converted into trivalent arsenic in human body. The WHO stipulates that the amount of arsenic allowed per day is 0.05 mg / kg. However, the arsenic content in dried kelp has greatly exceeded the above standards.
in order to ensure the safety of the edible seaweed, the edible seaweed can be soaked in sufficient water for 24 hours according to the characteristics of arsenic soluble in water. The water should be changed during the soaking process, and the effluent is dried and stored in the sun after 24 hours, in order to prevent arsenic poisoning.
