Organic raw kelp and dulse granules combined with sea salt is a Raw Food! We think you'll love the subtle taste and interesting look of Maine-made salt blended with our sea veggies. This blend contains enough of our iodine-rich kelp and dulse granules to provide 370 mcg of iodine per 1/4 teaspoon serving, which meets or exceeds the 150 microgram RDA for iodine. The book "Iodine, Why You Need It" by Dr. David Brownstein, says that most of us aren't getting enough iodine even if we eat lots of iodized salt. In fact, as a population iodine levels have dropped 50% in 30 years (according to a NAHNES data in 2000). The reasons are complex, but it's partly because many are turning from iodized table salt to sea salt and partly because some studies show the iodine in table salt may only be partly bio-available anyway. According to Dr. Brownstein, your thyroid as well as your entire endocrine system depends on iodine as an essential element.
