Seaweed as a nutrient for humans
There are many types of seaweed and at least 500 of these are edible. Seaweed is especially popular in Asia and it is now being used more and more in Europe for consumption in various products.
Because seaweed is grown sustainably, it does not need fresh water, soil or fossil fuels and so it lends itself very well as a food source. Seaweed also contains many vegetable proteins that do not affect the environment and can be processed well in products.
Dried seaweed is widely used as a seasoning. Because of the unique umami or salty taste that seaweed has, it can be used to give added flavor to many dishes.
Another application is that seaweed is processed in supplements, especially kelp supplements that boost health.
