Great wakame flakes that taste no different than any traditional japanese wakame flakes. However, the Eden brand has lower levels or did not contain certain metals than many other popular brands, according to testing by naturalnews.com. Of those results the Eden brand did have slightly higher levels of Cadium than some brands, and the concentration is still considered in the low range. Its low to no, concentration of other metals makes it one of the safest overall wakame flakes I could find. Since my family eats this on a regular basis, I've switched over the wakame flakes from Eden brands.
