Seaweed creating a vibrant ecosystem

Have you ever wondered how certain indigenous tribes maintain such good health? The answer mainly lies in their diets. They consume foods, which are now coming to be known as superfoods.


Superfood is a trend that is taking the internet by storm. It's a term referring to foods, that contain very minimal calories but offer a diverse range of nutritional benefits. After nuts and fruits, the one food that has been crowned as the next superfood is Seaweed. 


Tribes gathering seaweed


Even though it is gaining popularity now, seaweed has been the secret to the good health of several indigenous tribes, such as the Ainu of Japan, the Maori of New Zealand, Native American Tribes of the Pacific Northwest, Coastal Indigenous Peoples of Ireland and Scotland, Indigenous Peoples of Korea.



Are you wondering how the thing you have only consumed with Sushi can become a superfood? Here is how,


  • Seaweed is packed with lots of nutrients and minerals, which is very healthy for the body.

  • It is very rich in Vitamins like K, C A, and B

  • It contains minerals such as magnesium, calcium, iron, and iodine.

  • It can protect cell damage, due to the presence of antioxidants, carotenoids, and flavonoids.

  • Seaweed is a very good source of omega-3 fatty acids, which is beneficial for heart health.

  • It rectifies gut health and aids digestion, owing to the presence of a high quantity of fiber.


Types of seaweed

There are several types of seaweed. All with their own flavor profile and benefits-


  • Nori- This is the most common one. I am sure, all of you have heard about Nori. Especially those who love Sushi. Nori is high in vitamins A, C, and B12, Omega-3 fatty acids, and iodine. Once toasted, Nori becomes very crispy and can paired up well with a huge variety of dishes.

  • Dulse- This pretty-looking red-colored seaweed contains a high amount of potassium and iron. This seaweed can be eaten cooked or raw and adds an umami flavor when added to a dish. 


  • Arame- This seaweed is very high in calcium, iron, and iodine. When added to salads or stir-fried it adds a mild sweet taste and a soft texture. 


  • Spirulina- This mesmerizing-looking blue-green algae is packed with nutrients such as beta-carotene, B vitamins, and proteins. It is mainly sold in powdered form as a supplement for boosting immunity. It also has anti-inflammatory properties.

Seaweed smoothie recipe

I know, the main challenge we face to incorporate something in our diet, is how to turn that ingredient into something edible. Don’t worry!! I got you!! Here is a recipe for a delicious seaweed smoothie, that is not only going to make you feel nourished but will surely elevate your mood. And the best part? You can make it Vegan too. 


Seaweed farming is a very sustainable form of agriculture. It has numerous ecological benefits and very minimal environmental impact. Pioneers like Bren Smith (advocate for ocean regenerative farming, and the founder of GreenWave), Ocean Rainforest (leading European pioneer of large-scale seaweed cultivation), and many more, are working towards restoring the ecological balance of our oceans by advocating sustainable farming options such as seaweed cultivation.


This being said, for some taste pallets seaweed could be an acquired taste. However, if you want to enjoy all the nutritional benefits but avoid the taste, products such as powdered seaweed and capsules are available in the market. But always consult your doctor first before making seaweed a staple in your diet.
