seaweed and health

It began around 2013. When the international press started speaking with much enthusiasm about the anticipated health benefits of adding seaweed to our diets. Now, years later, every day one can find new articles in the media on the broader topic of seaweed and health. It's referred to as "superfood" and "new proteins" or "the green gold," even the "solution to predicted food shortages." Some scientific projects are even researching the medicinal benefits of some seaweeds.

For it to be healthy, seaweed must come from unpolluted seawater. The reason it is continually touted as "good for you" is because it not only contains interesting levels of minerals, vitamins and proteins found in our more traditional foods - seaweeds, predominantly the brown macro algae, contain something unique. Fucoidans, alginates and laminarins. These three don't exist in land based produce. And precisely those compounds offer very interesting health benefits. It would be too much to lists all of it here, but you can find a wealth of information on the internet, starting with Wikipedia.

Another reason seaweed gets the attention of health-conscious parties, is its role in reducing sodium intake. Many seaweeds, but specifically our Royal Kombu, contains far more potassium than sodium. But the list goes on. Royal Kombu contains high levels of calcium, iron, and iodine (important when you're pregnant). And then we have a long list of healthy compounds found in small quantities, referred to as "trace elements." Here two article about a number of scientific studies into Royal Kombu and more broadly Brown Macro Algae:

super combination

We dry our seaweed under 45 degrees Celsius, so that all nutritional values stay intact. It is commonly accepted that a combination of seaweeds in your diet, like a mix of brown seaweed and green seaweed, makes for a nutritional addition to our diets. These two types each have a unique nutrient profile, which makes them work so well in combination.

Laboratory testing shows us exactly what is present/absent in our cultivated seaweed. They contain an impressive list of minerals, vitamins and proteins (amino acids). But we would like to know more about the effects of eating seaweed. For example, what are the health benefits over time? This requires scientific research, in which countries like the US and UK are now taking the lead. To stimulate this type of independent research, Zeewaar offers its sustainably cultivated seaweed as well as seaweed farm access to any scientific party planning to study the health benefits of seaweed.


  1. whether any particular seaweed is healthy or not, depends foremost on the location it comes from because seaweed absorbs almost everything present in the water it lives in. The Eastern Scheldt, where Zeewaar has its farm, is a national park (Natura 2000) that is protected against industrial and farming pollution. For that reason, this is where our premium quality oysters, mussels, lobsters and shrimp come from. The water quality is monitored by the Dutch government.
  2. We use independent labs to test our seaweeds on the nutritional values, as well as the presence of heavy metals, PCB's, dioxins, and micro biology testing.
  3. All seaweed types contain proteins, and that has attracted worldwide attention. Studies have shown that proteins in Macro Algae are easily digestible by the human body. This is not the case for all protein sources out there, so this is a big win for us all. Any protein source provides potential to help feed the growing worldwide population in the near future. Keep in mind that the quantities of protein differ per seaweed type and per season.
