Learn All About Brown Seaweeds

kelp benefits
Kelp – an incredible brown seaweed

Seaweeds are classified as algae although they are often referred to as ‘plants from the sea’.  Brown Seaweeds constitute a major group of all the seaweeds and are rarely found in freshwater. 

All seaweeds photosynthesise, just as land plants do. However they do not produce flowers or have roots or systems for transporting water and nutrients. They all contain the light harvesting pigment chlorophyll which is synthesised and stored in the seaweed’s cells. Seaweeds also contain other pigments which are used to capture light for photosynthesis or to protect against harmful ultraviolet radiation. The pigments present in seaweeds are used to help classify them into three broad colour groups – red, green and brown.

Read on to learn more about brown seaweeds and why you should consider adding them to your diet!

What are Brown Seaweeds?

Brown seaweeds are brown because they have high concentrations of carotenoids such as yellowish-brown fucoxanthin.  This group includes some of the largest sea plants, some of them part of large under-water forests. There are about 160 species of brown seaweeds in New Zealand, and worldwide approximately 1,500-2,000 species.  Some brown seaweeds like Giant Kelp, can grow up to 60m tall!

Although grouped as ‘brown’, their colour may vary between hues of brown, orange and red. The most popular edible species of brown seaweed are: Kelp / Kombu, Wakame, & Sea Spaghetti.

What Nutrients and Minerals Do Brown Seaweeds Offer*?

Brown seaweeds are known for their high iodine content, but they contain high concentrations of minerals and trace elements, especially calcium, magnesium, potassium and zinc. They also contain Omega 3 & 6 fatty acids in a favourable ratio (1/2).

Brown seaweeds also contain other substances which may be key to resolving degenerative diseases including alginates (detox radiations and heavy metals), fucoidan (associated with cancer prevention and infections), Laminarin (cardio vascular health) and lignans (oestrogen related illness).

What are the Health Benefits of Brown Seaweeds?

As above, there are a number of areas where brown seaweeds have been researched and its found they have potential to have a remarkable impact on a range of health ailments.

The key value in eating brown seaweeds regularly (in carefully monitored quantities due to their naturally occuring high iodine level) includes a number of benefits for optimal health:

  1. Nourishing the thyroid gland & brain
  2. Balancing hormones
  3. Improving metabolism & facilitating weight loss
  4. Removing radioactivity, heavy metals & environmental toxins from the body
  5. Naturally inhibiting cancer cell growth
  6. Soothing the skin and the digestive tract
  7. supporting bone & joint health

There is ongoing research to explore how brown seaweeds may be critical to solving a range of degenerative diseases,  inhibit the growth of cance cells and even weight loss.  

How to use Brown Seaweeds in Your Cooking and Baking

Each brown seaweed has a unique flavour profile. Experiment with different seaweeds in your cooking to see which flavours you prefer.  Click here for the brown seaweeds we offer – Kelp, Kombu, Wakame and Sea Spaghetti.

Here are some ideas to get started with adding a little brown seaweed to everyday meals:

  • Drink miso soup with Wakame regularly.
  • Use Sea Spaghetti instead of noodles in soups or as an ingredient in winter salads
  • Sprinkle Kelp instead of salt on food; it tastes salty & provides a better balance of minerals. Just start with kelp salt which is a naturally iodised salt to easily replace the processed table salt and improve your iodine levels with no thought at all. Use our award winning seasoned kelp range (available in chilli, garlic or lemon) as a marinade or rub.
  • Use Kombu when cooking beans & pulses – it aids digestion & reduces cooking time, tenderising.
  • Make seaweed stock with Kombu: it is quick, easy, healthy & delicious
