Humans have been eating seaweed for millennia. Many early communities lived close to the shore because the seas offered a constant and dependable food source. Neolithic communities in Britain for example clustered around coastal lands where rich and diverse foodstuffs were readily available. The west coast of Scotland is peppered with brochs and burial chambers from Neolithic times and earlier. The farmers of those times would certainly have supplemented their shellfish and seafood diets with some of the local seaweeds.
Seaweed health benefits and seaweed eating have been mainly explored by island and coastal peoples. Japanese culture has developed seaweed cuisine to a notable level. The flavours and textures add a subtle and exotic element to Japanese food which has made it increasingly popular in the west. They have perhaps exploited seaweed's culinary possibilities more than any other nation. Where most nations manage one or two seaweed types at most, the Japanese have five common types in regular use. In Japan people take seaweed eating seriously; as much as 4 kilograms is eaten per person per year !
Seaweeds are algae and they have unique health and nutritional properties. Algae use sunlight to photosynthesise food for themselves but they are far simpler in structure than most land plants.
Here are some of the main types of seaweed available in the west. The main health benefits are described with each type. You don't have to trek down to the sea; most of them should be available in a health food outlet somewhere in your neighbourhood. Failing that, you can buy some of them mail order.
LAVER or NORI
Laver or lava (Porphyra umilicali) is the word for a type of kelp much used by the Irish and the Welsh. In Wales it is still made into flat cakes called lava bread. Japanese Nori is a similar plant; there are several good variants available. The Welsh still eat their lava bread with cockles and sometimes with bacon. It is now mainly harvested in Scotland.
Nori is rich in iodine and iron and quite high in protein. It is also a good source of vitamin C, vitamin A, potassium, magnesiumand riboflavin(B2). Not only does it have all these nutritional riches, it is also a low-fat food !
Nori is a type of laver sold in the west. It's an important part of Japanese, Chinese and Korean cuisines and is now a multi-million dollar industry. Nori tends to be sold as flat sheets or flakes. It is also often toasted. If you have eaten sushi, chances are that you have eaten nori; it is often used for wrapping rolled pieces of sushi.
The Japanese and Chinese industries are still quite labour-intensive. Ways to modernise seaweed production have been sought but so far no really intensive system has been developed. The seaweed grows on racks or ropes over 45 days. However, the harvesting is increasingly mechanised and the finished nori is produced and packed in modern factories.
Japanese nori is grown in the Ise Bay region - a mountainous and well-forested coastal area where the sea waters are still relatively pure. Development is restricted in order to protect the seaweed quality and purity, (though there is an international airport and some built-up areas).
DULSE
Palmaria palmata, or dulse is reddish brown and is accounted a delicacy by many. It has doubtless been harvested for many, many a century but the earliest recording of it is 1400 years ago; St Columba and the monks of Iona ate it. Icelandic peoples also used it from early times. Now it is being cultivated and sold as a gourmet food. In Nova Scotia it is called Sea Parsleyand is sold fresh. The Irish call it "dilisk"or "dillisk"and you can buy it as a snack food in some pubs.
You can just harvest it yourself from rocks where it has dried in the sun. It grows in the inter-tidal regions, so it is relatively easy to access. If you are concerned about salt levels (sodium) you can soak it overnight in a mixture of milk and water.
You should always make sure that you harvest from uncontaminated areas of shoreline. Take advice from your local authorities and environmental experts if in any doubt. Unfortunately, many coastal areas are far from clean because many pollutants from petrochemicals to human waste.
Dulse is exceptionally nutritious, containing around 10 - 20% protein and a whole slew of vitamins and minerals, including magnesium, ironand beta carotene (which the body uses to manufacture vitamin A). It is now being farmed in Ireland and elsewhere for its health benefits and for making skin care and cosmetic products.
CARRAGEEN (CARRAGHEEN) or IRISH MOSS
Carrageen, or Irish moss, (Chondrus crispus) is widely used in all sorts of food products because it has emulsifying and gelling properties. It is used to thicken foods and produces a colourless jelly-like consistency, so it is used in lots of commercial desserts. It's also the vegetarian answer to gelatine.
It has lots of nutritional and health benefits, too. In Ireland it was traditionally rated as a cold and cough remedy. It is rich in retinoland minerals.
KELP or KOMBU
Kelp (Laminaria digitata)is found in many areas of the world. It is a brown seaweed with literally thousands of varieties. It is found in all sorts of commercial products, from toothpaste to fertiliser. As it is exceptionally rich in iodine, it used to be the main source for preventing goitre and treating thyroid conditions. It is still highly rated by naturopaths and nutritional therapists for that use.
Kelp use has a long history. It was known in China by the eighth century and has long been a popular snack food and culinary ingredient in Japan. During the Highland Clearances in Scotland it was one of the industries which crofters turned to when they were evicted from their lands. Kelp was burnt to produce soda ash. (The later economic failure of the kelp industry was responsible for many families coming to seek a new life in North America).
As it also has binding and stabilising properties kelp is used in many commercial applications. However, it's a really great natural health food. It is sold in health food shops very often as Kombu (the Japanese name). The Chinese make a traditional soup stock called "dashi" from it.
Japanese kombu is usually Laminaria japonica.It is now extensively farmed around Hokkaido and in China in the Yellow Sea area. Arame, another Japanese seaweed is also a type of kelp.
Kelp or Kombu is a great source of iron, magnesiumand folate (vitamin B9).
WAKAME
Wakame (Undaria pinnatifida) is a type of kelp. It's a tasty and valuable seaweed which can be added into soups and stews. Wakame is mainly produced in Japan and the far east though there are now wakame producers in France (Brittany). It is regarded as a serious pest in New Zealand because it is invading coastal waters.
Recent research shows it to have anti-obesityproperties and to be very high in EPA, an essential fatty acid.
Wakame is a green seaweed with a slippery consistency and an almost sweet taste. It has a thick band of fibre in the centre which can be easily cut out to give a more palatable effect.
If you make soup with it you could be forgiven for thinking you were eating fish soup. It can easily be added in small amounts to lots of cooked dishes such as stir-fries and stews. It's also delicious as a side dish. The Japanese use it as part of miso soup.
Seaweed is available in most health food shops, including Holland & Barrett in the UK. You can also often buy seaweed in Chinese grocery stores. Some varieties are available on-line from Amazon, including Nori
.
There are several seaweed producers now in Ireland, Scotland and Brittany for example, which may supply local outlets.
If you buy your local (or near-local) seaweed you are helping sustain local industries and keeping the carbon footprint of your seaweed-eating within reasonable limits. Packed, dried seaweed is quite lightweight. Nevertheless, it is an enormous export industry in the far east particularly. If you live in the west, it would make sense to eat your local seaweeds in the main in order to help reduce the environmental costs of shipping.
The taste is fantastic and it adds another dimension to your cuisine. Seaweeds are full of valuable nutrients. (I know I felt almost immediately a lot healthier once I started eating them!)
Many seaweed harvesting companies use traditional methods. They also need pristine seas in order that their products are not contaminated by pollutants. Supporting these industries therefore, helps indirectly in the quest for a cleaner, less polluted planet.
There's no doubt that the many seaweed health benefits make it an excellent item to include in your diet - and it may well be a green thing to do, too. This is a cheap and natural health food which is available to almost everyone. It's certainly worth getting some seaweed health benefits into your life! Buy your seaweed from reputable sources, where possible and help sustain good environmental practices.

From the host's desk
Among all the seaweeds, my personal choice is the 'Guso' seaweed (see picture above) which is harvested from the shallow cyrstal-clear water around the many islands around the Philippines coast. Annually, several thousand metric tonnes are exported in their dried form to all parts of the world.
Today, because of strong recommendations from friends and relatives, these seaweeds are more frequently consumed. Many have found it helpful and effective in dealing with the following health conditions, namely :
a) reducing high cholestrol level remarkably;
b) lowering hypertension for many end-users;
c) controlling of hyperglycemia level (diabetes patients);
d) detoxification for the whole digestive and intestinal systems;
e) improving skin complexion tremendously, especially for the ladies.
For item (e), just grab a handful of the said seaweed and place them into a small bowl. Pour a certain amount of hot water and let the seaweed melted off and dissolved into the water. Leave the water to cool down and them wipe them evenly on your face.
Please Note
Do not throw away the water that is used to rinse the dried seaweed (which is usually slimy too). They are very beneficial to your potted flower plants, or fruit trees (grown in your backyard). Mine have grown to more healthy and blooming nicely after using such water, to water them.
The best way to consume such seaweed for optimum effect is to eat them raw, in the form of salad dishes. The choices are up to each individuals.
I used to grab a handful of them (bought freshly from the market, or after rinsing the dry ones in water, for about 2 - 3 hours) and place them in a bowl.
Add in slices of tomatoes, grapes or green apple, a tablespoon or 2 of apple cider vinegar and extra virgin oil. Some would like to sprinkle some sesame seeds to add flavours, or slices of onions. This side dish can be prepared on your table everyday. The children will love them too.
Try them today and you will enjoy the endless benefits from it for your whole family. Otherwise, you can also get some recipies from the sellers to guide you.
