Science and Research

Seaweed Health Benefits:
Seaweeds are known to contain huge amounts of iodine, much higher than the minimal amount required by the body. The body needs a recommended daily amount of around 150 µg of iodine while only one gram of dried brown algae (a type of seaweed) can contain 550-7000 µg of iodine while nori (the seaweed used in sushi) contains 100 – 300 µg of iodine.
Upper respiratory tract:
Due to the high salt and iodine content, seaweeds disperse phlegm effectively and reduce small nodules, called goitre, that are formed due to iodine deficiency. They also act as a diuretic and reduce inflammatory conditions.
Seaweeds are primarily made up of dietary fibers like agar, carrageenans and alginate. These fibers are not digested by the body and increase the feeling of satiety and decrease hunger pangs. Recently, they are being used as slimming agents and weight control pills.
