BY Penelope Judson 2018-06-09If you are concerned about the toxic arsenic contained in the kelp, you can soak it in clean water for six hours before buying it. You can change the water several times during the soaking process. After long-term immersion in kelp, there is a certain loss of nutrients, but it will not cause too much impact on its nutritional value.6
