Seaweeds from clean habitats
In the Delitas products the selection of algae has been done with great care. From Europe we import organic algae from Galicia, (Spain) and from Ireland. Also the selection of certified and fully labeled algae from Japan makes the risk of toxicity from heavy metals (usually hijiki algae) controlled within safe limits.
Because algae are among the healthiest foods in the world, because of the incredibly rich mineral content, fiber and other unique health benefits, the risks of toxicity can be prevented through the purchase of certified items.
It is known that in waters contaminated by heavy metallic elements – including arsenic, lead and cadmium – algae (like all marine organisms) can act as a sponge that absorbs these undesirable impurities. Some marine biologists actually use algae as a “bio-control” species to determine the levels of heavy metals in water bodies.
Among all the heavy metals found in seawater, the male appears to be more problematic when it comes to the risk of seaweed toxicity. Almost all algae contain traces of arsenic. Seal species containing arsenic are arame, hijiki, kombu, nori and others. However, among all types of these sea algae, other sea vegetables, hijiki stands out as a particularly high risk.
Over the period 2000-2005, governments in countries such as England, New Zealand and Canada issued public health recommendations and advised against the consumption of hijiki algae unless there is sufficient information to contain very low levels of this inorganic element arsenic). But if it is available in the form of certified and cultivated organic hijiki, then there is no danger. Such a product always indicates on its packaging the laboratory tests and in particular shows the safe limits that this ingredient contains in the algae.
Even the levels of arsenic found in other species of seaweed growing on the high seas were relatively small. The US Environmental Protection Agency (EPA) has set a reference dose (RFD) for the male, taking 0.3 micrograms per kilogram of body weight per day. For a person weighing 70 pounds, this amount is translated into 21 micrograms of arsenic. In seaweed research, dietary supplements containing dried algae (and which are best studied by fresh algae) give us data that we use when trying to assess the risk of male by seaweed. In many research studies, the amount of arsenic contained in a tablespoon (10 grams) of seaweed has an average of about 4-5 micrograms, or about 20-25% of RFD. While the intake of this level of male is well below the EPA limit for daily oral intake, there may be people who wish to avoid it. In this case the only guarantee to avoid exposure to this quantity is to use algae certified to indicate on its packaging that it does not contain arsenic.
Most certified items are purchased in dry form from major foreign companies and their reconstitution takes place in the production environment of the finished product. The company’s HACCP Quality System monitors and records all information that minimizes the risks involved.
