Sea vegetables, also known as seaweeds, have been used in traditional Japanese cuisine for centuries. Among the various types of sea vegetables, nori and wakame are the two most popular. In this article, we’ll take a closer look at these two sea vegetables and compare them in terms of their nutritional benefits, texture and flavor differences, culinary uses, health benefits, and more.
What is Nori?
Nori is a type of dried seaweed that is commonly used in the production of sushi rolls. It is usually sold in thin, paper-like sheets that are dark green or black in color. Nori contains a variety of vitamins and minerals, including vitamins A and C, iron, and iodine. It is also a good source of protein and dietary fiber.
In addition to its nutritional benefits, nori has also been found to have potential health benefits. Studies have shown that nori may help to lower cholesterol levels and reduce the risk of heart disease. It may also have anti-inflammatory properties and could potentially help to prevent certain types of cancer.
While nori is most commonly associated with sushi, it can also be used in a variety of other dishes. It can be crumbled and used as a seasoning, added to soups and stews, or even used as a wrap for sandwiches or other foods. Nori is a versatile and nutritious ingredient that can add flavor and texture to a wide range of dishes.
What is Wakame?
Wakame is also a type of edible seaweed that is commonly used in Japanese cuisine. It is sold dried, and when rehydrated it opens up to a silky texture, light green color, and mild flavor. Wakame is known for its high content of vitamins and minerals, including calcium, iodine, and folate. In addition, it is believed to have antioxidant and anti-inflammatory properties.
Wakame is often used in miso soup, seaweed salad, and as a topping for rice bowls. It is also a popular ingredient in macrobiotic diets due to its nutritional value. Wakame is harvested in the cold waters of the Pacific Ocean and is considered a sustainable food source. It is low in calories and high in fiber, making it a great addition to a healthy diet.
Nutritional Benefits of Nori
Nori is a great source of iodine, a trace mineral that is essential for proper thyroid function. It also contains high amounts of vitamin A, which is important for maintaining healthy vision and immune function. Additionally, nori is a good source of vitamin C, which acts as an antioxidant and supports overall health. Nori is also low in calories, making it a great addition to any healthy diet.
Moreover, nori is rich in minerals such as calcium, iron, and magnesium, which are essential for maintaining strong bones, healthy blood, and proper muscle function. It also contains a high amount of protein, making it a great option for vegetarians and vegans looking to increase their protein intake. Nori is also known to have anti-inflammatory properties, which can help reduce the risk of chronic diseases such as heart disease and cancer.
Nutritional Benefits of Wakame
Wakame is known for being a rich source of calcium, an essential mineral that plays a crucial role in maintaining healthy bones and teeth. It also contains high amounts of iodine and folate, which are important for proper thyroid function and healthy fetal development during pregnancy.

Texture and Flavor Differences between Nori and Wakame
Nori has a crispy texture and savory umami flavor that complements sushi rolls and other Japanese dishes. On the other hand, wakame has a tender, silky texture and a more subtle flavor that works well in soups, salads, and stir-fries.
Additionally, nori is typically used in its dried form, while wakame is often sold fresh or rehydrated from its dried form. This difference in preparation can also affect the texture and flavor of the seaweed. Nori can become chewy when rehydrated, while wakame maintains its tender texture even when cooked.
Culinary Uses of Nori
Nori is most commonly used in the production of sushi rolls, where it is wrapped around various fillings such as rice, vegetables, and seafood. It can also be toasted and crumbled as a topping for salads, soups, and noodle dishes.
In addition to its traditional uses, nori can also be used as a seasoning for other dishes. It can be ground into a powder and sprinkled over popcorn or roasted vegetables for a savory, umami flavor. Nori can also be used to add depth to homemade broths and stocks, or mixed into dips and spreads for a unique twist on classic recipes.
Culinary Uses of Wakame
Wakame is often used in miso soup, where it adds a mild flavor and a chewy texture. It can also be used in salads, stir-fries, and as a garnish for seafood dishes.
Aside from its culinary uses, wakame is also known for its health benefits. It is a good source of vitamins and minerals, including iodine, calcium, and iron. It is also rich in antioxidants, which can help protect the body against damage from free radicals.
Wakame is also used in traditional medicine for its potential to lower blood pressure and cholesterol levels. Some studies have shown that it may also have anti-inflammatory and anti-cancer properties. However, more research is needed to fully understand the extent of its health benefits.
Which is More Popular in Japanese Cuisine – Nori or Wakame?
Both nori and wakame are widely used in Japanese cuisine, but nori is the more popular of the two. Nori is a key ingredient in the production of sushi, which is one of the most famous Japanese dishes around the world. However, wakame is also used in many traditional Japanese dishes such as miso soup and seaweed salad.
Despite nori being more popular, wakame has been gaining popularity in recent years due to its health benefits. Wakame is a good source of vitamins and minerals, including iodine, which is important for thyroid function. It also contains fucoxanthin, a compound that has been shown to have anti-obesity effects.
Another difference between nori and wakame is their texture. Nori is thin and crispy, while wakame is soft and chewy. This difference in texture makes them suitable for different dishes. Nori is perfect for wrapping around sushi rice, while wakame is great for adding to soups and salads.
How to Cook with Nori and Wakame?
Nori and wakame can be rehydrated by soaking them in water for a few minutes before using them in recipes. Nori can be used as a wrap, while wakame can be added directly to soups and stir-fries. Both of these sea vegetables can also be toasted for extra flavor and crunch.
Aside from being delicious, nori and wakame are also packed with nutrients. Nori is a great source of iodine, which is important for thyroid health, while wakame is rich in calcium and magnesium, which are essential for strong bones and teeth. Additionally, both of these sea vegetables contain antioxidants that can help protect against cell damage and reduce the risk of chronic diseases.
If you’re looking for new ways to incorporate nori and wakame into your diet, try using them in sushi rolls, salads, or even as a topping for avocado toast. You can also experiment with different seasonings and spices to enhance their natural flavors. With their versatility and health benefits, nori and wakame are a great addition to any meal.
How to Store Nori and Wakame?
Nori and wakame should be stored in an airtight container in a cool, dark place, away from direct sunlight and moisture. It’s important to use them within a few months of purchase, as they can lose their flavor and nutritional value over time.
When storing nori and wakame, it’s also important to keep them away from strong odors, as they can easily absorb them. This means that they should not be stored near spices, onions, or other strong-smelling foods.
If you have purchased nori or wakame in bulk, it’s a good idea to divide them into smaller portions before storing them. This will help to prevent air and moisture from getting into the container and affecting the quality of the seaweed.
Health Benefits of Consuming Nori and Wakame
Sea vegetables like nori and wakame are loaded with essential vitamins, minerals, and antioxidants that can help protect against various diseases and promote overall health. Some studies have shown that consuming these sea vegetables may help lower blood pressure, cholesterol levels, and even reduce the risk of certain types of cancer. In addition, they are low in calories and high in fiber, making them a great addition to any diet.
Furthermore, nori and wakame are excellent sources of iodine, a mineral that is essential for proper thyroid function. The thyroid gland uses iodine to produce hormones that regulate metabolism, growth, and development. A deficiency in iodine can lead to thyroid problems, such as hypothyroidism or goiter. Consuming nori and wakame regularly can help ensure that your body gets enough iodine to maintain a healthy thyroid function.
Side Effects of Consuming Nori and Wakame
While nori and wakame are generally considered safe to eat, consuming excessive amounts of seaweed can lead to potential health risks due to high levels of iodine. It’s recommended to consume no more than a few sheets of nori or a small amount of wakame per day to avoid any adverse effects.
Additionally, some individuals may be allergic to seaweed and should avoid consuming it altogether. Symptoms of an allergic reaction can include itching, swelling, and difficulty breathing. If you experience any of these symptoms after consuming seaweed, seek medical attention immediately.
Which is Better for Sushi – Nori or Wakame?
Nori is the best option for making sushi, as it has a crispy texture and strong enough to hold the roll together. In contrast, wakame is too tender and not strong enough to wrap around the fillings in sushi rolls.
However, wakame is a great option for adding flavor and texture to sushi dishes. It is often used as a garnish or mixed into sushi rice to add a subtle umami taste. Wakame is also a good source of vitamins and minerals, including calcium, iron, and iodine, making it a healthy addition to any sushi dish.
Environmental Impact of Harvesting Nori and Wakame
Nori and wakame are sustainably harvested from the sea, making them a more environmentally friendly food choice compared to other meat and seafood alternatives. However, like any agricultural industry, it is crucial to ensure that the harvest is done in a sustainable manner to protect the ocean ecosystem and the future supply of these nutritious sea vegetables.
In conclusion, both nori and wakame offer a wide range of nutritional benefits and culinary uses. While nori is more popular in Japanese cuisine and better suited for sushi-making, wakame is known for its tender texture and subtle flavor that works well in a variety of dishes. When consumed in moderation, both nori and wakame can be a healthy and sustainable addition to a well-balanced diet.
One of the major environmental impacts of harvesting nori and wakame is the potential disruption of the natural habitat of marine organisms. The harvesting process can damage the seafloor and affect the growth and reproduction of other marine species. To minimize this impact, some seaweed farms use a method called “floating culture,” which involves growing the seaweed on ropes or nets suspended in the water, rather than harvesting it from the seafloor.
Another important consideration is the use of chemicals and fertilizers in seaweed farming. While some farms use organic methods, others may rely on synthetic fertilizers and pesticides, which can have negative effects on the environment and human health. It is important for consumers to choose seaweed products that are sustainably and responsibly produced, and to support companies that prioritize environmental stewardship.
