Edible seaweed

Edible seaweeds are seaweeds that can be eaten and used for culinary purposes.[1] They typically contain high amounts of fiber.[2][3] They may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae.[2] Seaweeds are also harvested or cultivated for the extraction of polysaccharides[4] such as alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food additives.[5] The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids.[6]

Seaweed as food is particularly popular in East Asia.

Most edible seaweeds are marine algae, a group containing few toxic (though some deadly) species, while freshwater algae are mostly toxic.
