A recent news report suggests seaweed contains fibre that helps lose weight more effectively than obesity drugs*.
Ayurveda claims that seaweed is cleansing and mildly nutritive seaweed’s are balanced for most constitutions, only increasing vata in excess. They are the highest plant source of minerals and make a good addition to people who have been mainly eating a meat based diet. They generally help to eliminate toxic heavy metals and radiation from the tissues. They do not absorb toxins from the ocean readily – acting rather to transmute these pollutants.
They are useful to treat tumors, cysts, edema, and the thyroid. It is one of the best foods to clear the plasma and lymph nodes. Seaweed’s can make an important addition to weight loss programs and counteract high cholesterol and fat in the blood.
Ayurveda considers seaweed to be more tamasic due to it growing low in the ocean. Hence, it is not traditionally used as food. It is still valuable as a supplement or as a food for Ocean cultures. Seaweed is considered to reduce Pitta and Kapha and only increase Vata slightly.
