Exploring the world of edible seaweed can be a transformative journey for your health and beauty. From a refreshing seaweed salad to a garnish on your favourite dish, seaweed is more than just an oceanic plant. It’s also a powerhouse of nutrients and flavours. Let’s delve into the specifics of hijiki vs ogo seaweed, and how they can enhance your plant-based (or plant-friendly) diet.

Understanding Hijiki

Hijiki seaweed, also known as Tot (in Korean) is widely consumed in Korea, Japan, and China.

Hijiki stands out in the many types of Japanese seaweed, known for its green-tinted dark brown strands. Unlike the broad leaves of other varieties of seaweed, hijiki is visually distinctive. It looks almost like tiny, stringy bits of tea and is often found as dried seaweeds in stores. Therefore it requires a soak in water before it can be transformed into a delicious part of your meal.

When it comes to culinary uses, this type of seaweed is versatile. It adds a unique flavour and texture to a seaweed salad, stir-fries, and even rice bowls. In Japanese cuisine, it’s a key ingredient in many dishes, offering a satisfying crunch and an earthy, slightly sweet flavour that is distinctly different from other seaweeds

Nutritionally, hijiki is a powerhouse, packed with dietary fibre, vitamins, and minerals, making it an invaluable addition to a health-conscious diet.

Is Hijiki Seaweed Safe to Eat?

While popular, there are concerns regarding the arsenic content of seaweed. When it comes to hijiki, even though this plant is a nutritious food source, some studies have pointed out that it tends to absorb much more arsenic compared to other fresh seaweed, and much more than rice which is already regarded with concern when it comes to arsenic.

There is also a growing global stance on hijiki’s safety. In a significant move back in 2001, the Canadian government advised the public against eating hijiki. This cautionary stance was soon echoed by the UK, the rest of Europe, Australia, New Zealand, and China, with these regions advising against its consumption and even going as far as banning imports and sales of hijiki. 

Interestingly, in Japan, where hijiki is not only consumed but also cultivated as an industry, the advice given is one of moderation rather than outright avoidance. This varied global response to hijiki highlights the importance of being informed and cautious about the foods we choose to include in our diets.

How Do You Remove Arsenic from Hijiki?

It’s generally advised to soak and rinse hijiki thoroughly in cold water before cooking, which can help reduce any potential arsenic content.

What Does Hijiki Seaweed Taste Like? 

This unique seaweed has an earthy, slightly nutty flavour, which is why it’s a popular choice in various Asian dishes. Its unique taste and texture make it a favourite in Japanese cuisine, particularly in seaweed salads and as a flavourful addition to side dishes.

Is Hijiki Seaweed Healthy? 

Absolutely. It’s a fantastic source of dietary fibre and essential minerals, contributing to a balanced diet. However, when considering the arsenic in it (absorbed from seawater), you may decide that it’s not a healthy choice for you. 

Exploring Ogo Seaweed

Ogo seaweed, a form of red algae, stands out with its unique culinary and nutritional profile. Known for its thin, wiry strands, ogo is a popular ingredient in Hawaiian cuisine and is widely appreciated for its versatility in various dishes. Unlike kelp, which is a type of brown algae, ogo falls under the category of red algae and is often used in a fresh form, particularly in salads and as a garnish.

Ogo seaweed offers a light, slightly briny flavour, making it a delightful addition to dishes where a subtle taste of the sea is desired. Its texture and taste make it a favourite in dishes like poke bowls, where it complements the flavours of fresh fish and other ingredients.

In addition to its culinary uses, ogo seaweed is also known for its nutritional benefits. As a type of red algae, it is a good source of vitamins, minerals, and has a unique nutritional composition that adds value to a balanced diet. Whether used in traditional Hawaiian dishes or as a creative addition to salads and seafood dishes, ogo seaweed brings a touch of the ocean’s bounty to the table, offering both health benefits and delightful flavours.

The Seaweed Wellness Boost 

Why Do I Feel Better After Eating Seaweed? 

The answer lies in the rich array of nutrients these seaweeds provide. They are packed with vitamins, minerals, and dietary fibre, which are known to improve digestion, regulate blood sugar levels, and aid in weight loss. These nutrients, combined with the unique compounds found in seaweeds, contribute to an overall feeling of well-being.

However, not everyone can or should indulge in these oceanic treasures. 

Who Should Avoid Eating Seaweed? 

Those with thyroid conditions or sensitivities to high amounts of iodine should be cautious. Seaweeds, especially certain types of kelp, can contain significant levels of iodine, which might affect thyroid function.

Why Can’t You Eat Seaweed Everyday? 

Consuming seaweed in large quantities daily could lead to an excess intake of iodine and potentially heavy metals, which might pose health risks.

Despite these considerations, the occasional inclusion of seaweed in your diet can be highly beneficial. The key is to enjoy it in moderation and be mindful of the type and amounts of iodine and other nutrients it contains. As with any food, balance is crucial for reaping the maximum health benefits.

Incorporating Hijiki and Ogo into Your Diet

Integrating hijiki and ogo into your daily meals offers a delightful fusion of umami flavour and nutrition. These seaweeds are staple ingredients in several Asian countries but are also gaining popularity in the western world for their health benefits. Known for being high in dietary fibres, vitamins, and minerals, and low in dietary fat, they are an excellent alternative to animal-based proteins. 

The protein content in green seaweeds can be 10 – 25% of its dry weight. For red seaweeds like ogo, it can rise to as high as 47%.

A seaweed salad is a great starting point to enjoy these nutrient-rich seaweeds. The earthy flavour of hijiki also complements rice dishes and noodle dishes. This offers both a unique taste and a significant nutritional boost. Their unique ability to adapt to different recipes makes them both versatile ingredients in any kitchen.

Miso soup

If you’re new to cooking with seaweed, start by adding small quantities to familiar dishes. Hijiki can be a great addition to miso soup or mixed with soy sauce and sesame oil for a simple, flavourful dressing. 

Ogo, on the other hand, can add a splash of color and a hint of the sea to your sushi rolls and noodle dishes. Its transformation from a red seaweed to a bright green color when cooked makes it not only a tasty but also an attractive addition to any plate.

Incorporating these options, whether as dried or fresh seaweed, is about embracing their nutritional power. Their high protein content, coupled with a rich array of vitamins and minerals, makes them an attractive food choice. Even more so for those exploring plant-based diets. Whether you’re dining in a Japanese restaurant or cooking at home, hijiki and ogo offer a world of culinary possibilities. Both in Asian cultures and the western countries.
