Nori Profile
Also known as- Porphyra spp, Nori Seaweed, and Pacific Seaweed.
Introduction
Nori is perhaps best known here in the U.S. as a wrap for sushi, but it has a long history of use in traditional Chinese Medicine (TCM). Porphyra is a red seaweed that grows off the coast of Japan, where seaweed has always been an important food source. Like most seaweeds, Nori is very high in mineral content which accounts for up to 40% of its dry mass. The most important of these micronutrients is iodine * a very small portion of Nori provides well over the adult recommended daily intake of iodine, which is vital for proper thyroid functioning. In TCM, Nori is used to promote healthy circulation and to combat thyroid problems.
Nori is also rich in carotenes, vitamin C and vitamin B12, which is seldom found in land plants. In Japan, herbal formulations containing Nori are used to treat ïsoft swellings' such as goiters, and lung conditions. At 28% protein, Nori has more protein than sunflower seeds and wheat germ, both promoted as good sources of protein for those who eat no animal products. Its nutty, sweet-salty flavor makes it a popular addition to soups and salads.

Summary
Like most seaweeds, Nori is high in important minerals and nutrients, particularly iodine. Among the conditions that may be eased by eating Nori regularly are goiter, low thyroid function, kidney disease, fatty cysts, painful urination, hypertension, nervous disorders, edema, warts and indigestion. Much of the beneficial effect comes from its diuretic effect and from the high mineral and iodine content. Nori may also help the body break down fatty foods and fried foods. Nori also has some antibiotic properties which may help the body to resist infection.
Precautions
Because of the iodine content in Nori, it is recommended that consumption be limited, particularly by those being treated for low thyroid function.
