Seaweed & microalgae

Nori, wakame, dulse, spirulina… the sea garden.

Why?: Their fibers (alginates, fucoidans, agars) exist in no land plant — a whole niche of bacteria feasts on them.
Tip: Start with nori and wakame, mild and easy; moderate doses to keep iodine intake reasonable.
Counting: Fresh, dried or rehydrated, as flakes or as sheets. Powdered microalgae (spirulina, chlorella) tick too, at food doses.
The app's landmark: A serving of about 10 g, every 3 days.
Molecules: Seaweed polysaccharides
