Brittany and specially the North coast is known for its high concentration in algae. They are famous abroad, above all in Japan, big algae consumers.




Roscoff, a small city on the littoral is pretty well endowed : 800 species out of 1500 compiled in Brittany in 2000. Probably others must have been discovered.

The location of Roscoff explains why it has such a wide variety of algaes : the Gulf Stream allows a water temperature that doesn’t change a lot. The Stream gives a good waterquality.

Now, look at the shore and at the algae lying on the sand. You’ll see 3 colors : green, red and brown.



Each color is on a specific place on the shore. The brown ones are under the sea, then you have the red ones and the green algae are the closest to the earth.

Here in Brittany we have had lots of problems with the green ones. Thanks or because of fertilizers and nitrates from our pigs breeding, they were too many. It used to be a real annoyance. It's getting better but before on some beaches you could not walk or swim because they were doing a really too thick cover on the littoral.

For a really long time, seaweeds were used as fertilizers by farmers.



If Japanese eat them for a long, long time, we are just starting to be interested in them.
We do use it as gelling agents : when you buy an applepie in a shop and you are amazed by the nice shaped apple segments, well don’t think too much : the compote has been mixed with algae to make those nice perfect pieces of fruits.

Algae are also used as dietary supplements. They are full of vitamins, minerals, calcium, proteins… Sprinkle them on your salad.

In thalassotherapy centers they are used to help your body to recover… Your wrinkles will dicrease, your orange peel disappear, your hair will be beautiful … Used in cosmetics, we make lots of products with algae extracts : from anti-aging creams to oil to fight cellulite, skin care products or algae shampoo… They are everywhere. And to use them, you need to mix them as algae can’t be dissolved in water !!!
