Serving size, prep, and portion notes for agar-agar
Agar agar is the gelling fibre pulled from red seaweed and sold as E406, and it is one of the very few ingredients in this database that grades clean on every single trigger column: histamine, salicylate, oxalate, nickel, sulfite, glutamate, gluten, lactose, every FODMAP group, lectins and fermentability. That surprises people who avoid seaweed, because whole seaweed is a heavyweight for salicylates and free glutamate. Agar is not whole seaweed. It is a purified galactose polymer, stripped of the compounds that make kombu and nori a problem, and human enzymes cannot break it down at all, so it passes through as inert bulk.
Watch for
It is a bulk laxative before it is anything else. Agar swells to many times its volume in water, which is exactly why a teaspoon sets a whole pan of liquid, and why taking it dry or with too little fluid can lodge in the throat or the bowel. Always dissolve and boil it into the liquid rather than swallowing powder. / Recipe quantities are tiny, usually under one percent of the dish, so the fibre load from a set dessert is small. Trouble tends to come from agar sold as a slimming or constipation supplement, where the dose is far higher. / Low iodine protocols before thyroid scanning generally ask you to drop seaweed derivatives including agar, alginate and carrageenan. Purification is not the same as removal, so follow the protocol rather than reasoning from the ingredient list. / Not a substitute for gelatin one for one. Agar sets firmer and at room temperature, so cooks who swap by weight get a rubbery result and sometimes blame the ingredient for a texture problem rather than a ratio one.
