I have a recommended read for those who are interested in the health benefits of seaweed, which you can find here. I became interested in seaweed once we stopped using iodized table salt and switched to unprocessed pink salt, which I buy here and here.
It's amazing all the health benefits that can be derived from seaweed. It's a very inexpensive way to provide trace minerals and many wonderful health benefits for yourself and your family. Just be sure that the seaweed you buy is from a clean water source. I personally would avoid buying any from Japan at this time due to the nuclear spill that happened during the earthquake earlier this year. Be sure to read the section in Valerie's book about how much seaweed to take and what kinds to take before you buy your supply, as you do want to be careful not to eat too much seaweed.
I bought our seaweed from Mountain Rose Herbs and have stored it in a jars in my pantry. I alternate the types that we use. If I cannot hide the taste in food, then I put it in capsules for my husband, which is easy to do and a lot cheaper than buying it already encapsulated. Mountain Rose Herbs sells a capsule machine that is very inexpensive.
