Seaweeds like kelp can protect us from a wide range of
toxic elements in the environment, including radiation by-products, converting
them into harmless salts that our bodies can eliminate. Natural iodine in
seaweeds can reduce by almost 80% radioactive iodine-131 that
is absorbed by the thyroid. Seaweeds are so effective that even the
former U.S. Atomic Energy Commission recommended that people consume
two to three ounces of seaweeds a week (or 2 tbsp. of algin supplements a day)
for protection against radiation poisoning.
