Nori seaweed, scientific name Porphyra umbilicalis, is one of the most famous red algae in the world. It is indeed one of the ingredients of sushi, the typical Japanese dish based on rice, fish or vegetables. But nori seaweed is appreciated not only for its culinary use, it has also important healthy properties. First of all, nori seaweed is an important source of proteins, all highly digestible (Cian et al, Mar Drugs, Aug 2015). Moreover, this amazing seaweed also contains iodine, but to a lesser extent than other seaweeds, vitamin B12, and therefore can be integrated in the diet of vegetarians and vegans where often a vitamin B12 deficiency may be observed. Nori brings also vitamins A and C, iron and the precious fatty acids omega 3, that are not altered as a consequence of the processing of the seaweed such as drying and roasting (Watanabe et al, Nutrients, May 2014 - Watanabe et al, J Agric Food Chem, Jun 1999 - Masuda et al, Biosci Biotechnol Biochem, Oct 2015 - USDA Database). Finally, on the basis of scientific studies, the nori seaweed has been demonstrated to be able to counteract high levels of cholesterol (Bicanegra et al, Br J Nutr, Feb 2008). When you buy nori seaweed it may be in the form of sheets, you can use them to prepare a delicious vegetarian sushi, you can find the recipe in the Healthy Recipes section of the app, or you can cut the seaweed into pieces and add it to vegetables and salads, it will give flavor, healthy properties and will replace the salt.
