Salt, spice, seasoning – easy ways to eat seaweed

Updated: Jan 30, 2023



With an impressive variety of health benefits, seaweed salt and seasoning mixes are an easy first step to introduce seaweed into your diet.


Seaweeds offer an impressive variety of micro and macronutrients that are hard to go past. Nutritionist Sarah Leung, the founder of Alg Seaweed, says these include vitamins B12, C, A and K, as well as iodine, iron, calcium, magnesium and antioxidants, although this does vary from species to species. Seaweeds also have dietary fibre, protein and omega-3 fatty acids.


Iodine is of particular importance, she says, as many Western-style diets are deficient in this crucial micronutrient. Iodine, found in higher concentrations in brown seaweeds, is an essential micronutrient crucial for thyroid health, brain development and children’s growth.


Sprinkling a little seaweed seasoning on your food is one way to effortlessly boost your iodine intake, particularly where brown species such as kelps and wakame are used.


Seaweed adds depth of flavour to your meals, providing umami – which is one of the five taste elements that build our perception of flavour, along with sweet, salty, bitter and sour. Many seaweeds are high in the chemical compound glutamate, although it varies from species to species.


Glutamate is the basis of umami. In fact, the Smithsonian Magazine in the US reports that monosodium glutamate (MSG) was created in Japan as a commercial additive to mimic the flavour-boosting power of seaweeds. Seaweeds are a traditional part of many Asian cuisines, but your favourite Australian dish will also benefit from the addition of a little natural flavour enhancement, from scrambled eggs to steak and chips, soups and a hearty winter casserole.


More flavour, less salt


Seaweed provides a boost to everything from traditional Asian cuisine to Australian favourites.


One of the key benefits of using a salt seaweed mix is that the extra umami allows you to use less salt – sodium chloride – for the same flavour hit, according to marine scientist and founder of PhycoHealth, Dr Pia Winberg.


Pia says Australians consume up to twice the recommended daily allowance of five grams of salt. Most of the excess comes from processed foods such as sausages, preserved meats, snacks and ready-to-eat meals, where it’s used as both a flavour enhancer and a preservative.


Health issues related to too much salt consumption include water retention and high blood pressure. It has also been linked to an increased risk of heart disease and stomach cancer.


If you’re trying to cut back on the sodium, seaweed can help without sacrificing flavour. Or maybe you’re just keen to see what even a sprinkle of seaweed can do for your health and the flavour of your food. (#seaweedeveryday)

Asian spice blends such as Shichimi Togarashi commonly include seaweed.

Pure seaweed


Pure seaweed is also available as an ingredient that you can use in your own salt and spice blends, or simply for its own sake. You can make your own ground seaweed by blitzing dried seaweed to a powder in a blender. Dried seaweeds are readily available from Asian grocers, along with a range of seaweed spice mixes. But pre-prepared products offer greater convenience and quality control, so consider supporting Australian-grown ingredients and businesses with some of the following, or those listed above


• Golden Kelp Powder, Golden Kelp Granules and Smoked Golden Kelp GranulesSea Health Products

These are all produced from golden kelp harvested from the NSW coastline.

• Tasmania Wakame Alg Seaweed

This product is made from wakame, a brown seaweed hand-harvested by divers in Tasmania.


• Raw Tasmanian Kelp MealMindful Foods

The kelp species isn’t specified for this product, but the retailer notes it is high in iodine, as many kelps are. This one has 180 micrograms per teaspoon – which is more than the average recommended daily intake of 150 micrograms, so a little will go a long way.


A note on iodine

Brown seaweeds and kelps such as kombu found in Asian grocers can be exceptionally high in iodine. Red and green seaweeds have much lower iodine levels. While iodine is an essential micronutrient, too much can be toxic. It's an issue that the Australian seaweed industry is highly aware of and producers are careful to control.


Pia Winberg explains: "You only need about a teaspoon of iodine for your whole life, but it is essential for the whole journey." Sarah Leung likewise urges caution on the use of brown seaweeds and highlights the need to check the iodine content to ensure you don't exceed the upper limit for daily consumption, which is 1100 micrograms.
