Will Eating Sea Kelp Save Us From Radiation?
People are flocking to local health-food markets such as Mother's and Whole Foods for sea kelp--both in tablet form and actual food form (including nori seaweed sheets, dulse seaweed flakes and whole wakame seaweed)--as it contains iodine, believed to fend off radiation poisoning.
At Mother's Market in Laguna Woods, nutritionist Ren Moore says sea-kelp products have been "flying off the shelves," particularly last week when it was forecast that a plume of radiation was heading this way. She says the products are "definitely safe," as iodine is "very cleansing and can help push out heavy metals that may be in the system."
Though other experts say iodine must be taken in extremely high doses to be effective, according to West Hollywood Patch, sea-kelp tablets average 150 micrograms of iodine, the USDA recommended daily dose. Patch notes that other foods that contain iodine in healthy amounts include yogurt, cow's milk, eggs, strawberries, mozzarella cheese, fish and shellfish.
Some of those in fear have instead grabbed the hard stuff--potassium iodine pills, which are also available at some health-food markets and contain thousands of times more iodine than sea kelp. But experts have warned against doing so, as the side effects can potentially include life-threatening allergic reactions and damage to the thyroid gland.
So there's the tough answer. Sea kelp probably doesn't have have enough iodine to be effective, but consuming a higher amount of iodine may be unsafe.
More important to remember is that we don't have to worry about this right now. Or, hopefully, ever.
