The origin and much of Wakame seaweed’s history is discovered in Asia, specifically in Japan. Belonging to cold temperate coastal areas of Japan, Korea, and China, in current years wakame has become developed in temperate regions all over the world, including New Zealand, the United States, Belgium, France, Great Britain, Spain, Italy, Argentina, Australia and Mexico.

How is Wakame Farmed?

Wakame cultivation was first studied at Dalian, northeast China, by Japanese scholar Youshiro Ohtsuki who patented cultivation methods in 1943. Considering that the mid-1960s wakame seaweed has been thoroughly farmed there at a commercial level, however it can likewise be collected from the wild. In the Republic of Korea, growing of wakame began in 1964, and was largely established, promoted and industrialised throughout the 1970s, at that phase accounting for 30% of seaweed farming production in 2013.

In China, comprehensive production started in the mid-1980s, mainly in two northern provinces which have actually because ended up being the main wakame producers worldwide. Intake of this macroalgae as a seafood is divided in two categories; the processed midribs are taken in inside China, while the sporophylls and blades are primarily exported to Japan and other Asian nations.

In 1983, wakame farming was intentionally introduced into the North Atlantic in the coastal locations of Brittany and initially cultivated at 3 websites. Wakame growing is also being established in Northwest Spain.

Coming closer to house, in 2010, the New Zealand federal government authorized business harvest and farming of wakame under certain conditions– basically, that it be collected from a man-made structure. There is still much work to be performed in this space as a few of the New Zealand regulations are dated and complicated. The more we learn about wakame, the easier this should become.

Wakame as an ‘Intrusive Types’– aka a ‘weed’!

Interestingly, wakame has been regarded as a poisonous intrusive seaweed in nations aside from those where it is considered to be native. It is believed that wakame was first presented to foreign waters through the ballast water of freight ships from Asia, as the spores (gametophytes) included in the water can make it through long-distance journeys.

In New Zealand, wakame remained in fact declared an undesirable organism in 2000 under the Biosecurity Act 1993. It was first found in Wellington Harbour in 1987 and it is thought it likely shown up in our water as hull fouling on shipping or fishing vessels from Asia. Wakame is now discovered throughout our marine environment in New Zealand, from Stewart Island to as far north as Karikari Peninsula. Although it is an intrusive seaweed, in 2012 the government allowed for the farming of wakame in Wellington, Marlborough and Banks Peninsula.

Wakame spreads in two ways: naturally, through the millions of microscopic spores released by each fertile organism, and through human activities, the majority of commonly via the hull of shipping vessels or marine farming devices. It is a highly successful and fertile species, which makes it a major intruder. However, its impacts are not well understood and can differ depending upon the place.

Is Wakame a Friend or Enemy?

So as we learn about wakame, do we see it as a pal or opponent? The downside of wakame is that it is intrusive and can change the structure of environments, particularly in locations where native seaweeds are absent. By forming a dense canopy, it shades the sub-canopy, and can affect the development of slower-growing native seaweed types. For example, in New Zealand the native coralline algae which are necessary for paua (edible marine snail) settlement were partly displaced by wakame, leading to decreased paua quantities.

Furthermore, this invasive seaweed can affect not just the biodiversity of flora, however also the fauna communities which are based upon these phytogroups. Wakame can grow on reefs which use havens for fish, and slowly result in environment loss of fishes that dwell on the reefs. Research studies carried out in the Nuevo Gulf showed that the elimination of wakame from attacked sites led to a boost in the biodiversity at those places.

Research study shows that the wakame seaweed or sea vegetable has the potential to end up being an issue for marine farms due to the fact that it increases labour and harvesting expenses, due to fish cages, oyster racks, scallop bags and mussel ropes ending up being covered. This growth can also restrict water flow through cages.

On the flip side, Pacific Harvest is proud to use a clean, ethically harvested wild wakame, which is densely healthy and beneficial for health. The responsible harvesting and proper drying of wakame, and subsequent use of it as a surprisingly useful cooking area pantry staple, suggests we rid our oceans of a ‘pest’, lower expenses of obliteration, and add to a circular economy.

Wakame vs. Nori (Plus Other Seaweed)

Prior to we begin comparing some common seaweeds, let’s answer this concern: Is seaweed a vegetable?

Technically, seaweed is a kind of algae, however seaweeds are often described as “sea vegetables” and often treated as vegetables for culinary functions.

What eats seaweed? In addition to people, seaweed (in its natural environment) is commonly consumed by sea urchins, sea snails and plant-eating fish, such as the rabbit fish and parrot fish.

There are three main ranges of seaweed frequently utilized as food: wakame, nori and kombu seaweed. However, these are definitely not the only edible seaweeds.

Other consumable options, consist of

  • kelp (offered as fresh or dried kelp, as a supplement or in kelp powder kind)
  • ogo seaweed (generally used in dried kind for poke dishes)
  • dulse seaweed (frequently utilized as fresh, raw dulse or dulse flakes)

While wakame is eaten fresh or dried, nori is generally readily available in dried form. What is nori? It’s the most common papery seaweed covering for sushi rolls, and unlike wakame, it is never ever soaked prior to serving.

Nori is best eaten wrapped around other items (like sushi) or toasted.

Kombu belongs to the kelp household, and like wakame, it’s a brown seaweed. Kombu is frequently used to make dashi, a flavorful broth traditional to Japan and used to make miso soup.

Kombu and wakame have many overlapping health benefits and a comparable taste profile, however wakame is a little sweeter. Both kombu and wakame are commonly utilized in seaweed salads and soups.

Kelp belongs to the brown algae class (Phaeophyceae), and kombu is a specific range of kelp that’s very typical in Japanese, Chinese and Korean food. It can be utilized in salads, soups and smoothies, and there’s likewise kelp sushi.

Just like “land vegetables,” sea vegetables likewise have unique private health advantages in addition to numerous overlapping advantages. In general, wakame, nori, kombu and kelp are all definitely different yet share similarities in their taste profiles, uses and potential health advantages. [6]

Where to Purchase Wakame

Many Asian markets will have wakame, but other grocery stores might have wakame in the worldwide aisle, or in a section devoted to sushi, where the sushi rice, soy sauce, and nori are equipped. Another option is to discover it online. Wakame is most typically discovered in small bags in its dried form, however the dry salt-preserved kind will remain in the refrigerated area, most likely in an Asian market rather than the common supermarket. [7]

Side Effects of Seaweed

The seaweed advantages and side effects go together. An advantage to a single person may be an adverse effects to another.

The high-fiber material in seaweed can assist food digestion, but it can likewise cause digestion pain. Each gram of fiber adds up, and numerous portions of seaweed daily can easily push you over the advised daily allowance of fiber. Excessive fiber can cause bloating, gas and irregularity.

Individuals with health problems related to the thyroid needs to be specifically careful of overconsuming seaweed because of its high iodine material. According to a March 2014 research study published in Nature Reviews Endocrinology, excess iodine consumption does not have significant repercussions in the average person. Nevertheless, individuals with particular threat elements connected to thyroid diseases– such as hypothyroidism and hyperthyroidism– may discover that too much iodine can affect their thyroid function and thyroid medications.

One adverse effects of consuming seaweed is connected to the environment rather than the real food. The majority of the world’s seaweed is grown in China, but Korea and Japan are also major manufacturers of seaweed. There is concern that seaweed grown on Japanese coasts is polluted by radioactivity arising from the Fukushima nuclear mishap in 2011. A January 2014 research study released in the Journal of Plant Research study discovered polluted samples of algae. However, researchers do not recommend restricting your seaweed consumption due to potential radioactive exposure.

Another negative effects related to the environment is heavy metal exposure. According to a February 2018 study published in Scientific Reports, red seaweed contains considerably higher levels of copper, nickel and other metals compared to brown seaweed. Though researchers discovered heavy metals like lead and mercury, they report the threat level is low. However, they suggest the routine security of metals in seaweed.

When it pertains to seaweed and seafood, checking the source of your products will assist prevent contamination. The health dangers are low, but getting to know where your food originates from becomes part of being an informed, health-conscious customer. [8]


The right amount of wakame consumption may vary from one person to another. For the best guidance, you need to seek advice from a nutritional expert, a dietitian or another health specialist.

Usually, many people who regularly consume wakame consume percentages at a time, especially if the wakame is mixed in a soup or in sushi rolls. Be cautious not to eat excessive wakame, as it may lead to negative effects, as mentioned above. [9]

The Bottom Line

Wakame is an extremely nutritious, edible seaweed that can add a variety of minerals and vitamins to your diet for a low number of calories.
