Nori (海苔) is the Japanese name for edible seaweed (a "sea vegetable") species of the red algae genus Pyropia, including P. yezoensis and P. tenera. ALL of our Nori Sheets, Flakes, and Powder are all made from Porphyra Yezoensis and only the top 15 to 20 percent of Harvest makes our grade for item production. Modern cultivation of Porphyra did not occur until the 1960's, as a result of the discovery of the Conchocelis phase. 10.3322/canjclin.49.3.138, Shimizu H, Ross RK, Bernstein L, Yatani R, Henderson BE, Mack TM: Cancers of the prostate and breast among Japanese and white immigrants in Los Angeles County.

(김), also romanized as kim, is the Korean name for edible seaweed species in the genera Pyropia and Porphyra, including P. tenera, P. yezoensis, P. suborbiculata, P. pseudolinearis, P. dentata, and P. seriata. The biology of Pyropia, although complicated, is well understood, and this knowledge is used to control the production process. Murata M, Nakazoe J: Production and use of marine algae in Japan. The effects of Porphyra tenera extracts on the immune system are largely unknown. Consumption of kombu per Japanese household dropped further to 450 g in 2006 (elders ate up to four times more than those under the age of 29) [19]. Latin names: Nori (a type of red algae) Porphyra yezoensis and Porphyra tenera Kombu (a type of brown algae) Saccharina japonica or Laminaria japonica Dulse (a type of red algae) Palmaria palmata Wakame Undaria pinnatifida Hijiki (a type of brown sea vegetable) Sargassum fusiforme What is Seaweed? Endocrinol Jpn 1988, 35: 391–398. The three most popular seaweed products in Japan are nori (Porphyra), wakame (Undaria) and kombu (Laminaria). Processing of raw product is mostly accomplished by highly automated machines that accurately duplicate traditional manual processing steps, but with much improved efficiency and consistency. Below is the average iodine content of three different dried seaweeds (8): Kelp is one of the best sources of iodine. In 1999 the age-adjusted breast cancer mortality rate was three times higher in the US than in Japan [42]. lavers (nori) were determined by both Lactobacillus leichmannii ATCC 7830 microbiological and intrinsic factor chemiluminescence methods. In the 21st century, the Japanese nori industry faces a new decline due to increased competition from seaweed producers in China and Korea and domestic sales tax hikes. The industry was rescued by knowledge deriving from the work of British phycologist Kathleen Mary Drew-Baker, who had been researching the organism Porphyria umbilicalis, which grew in the seas around Wales and was harvested for food (bara lafwr or bara lawr), as in Japan. Edited by: Wilson JD, Foster DW, Kronenberg HM, Larson P. Philadelphia: W.B. Based on previous estimates and records, dried seaweed consumption of 4-7 g/day [17, 22, 30, 31] results in iodine intakes between 79 and 139 μg/day from nori and wakame when calculated using dried iodine contents of 16 and 42 μg/g respectively [18]. Daily iodine intake of the Japanese based on 24-hour diet samples generally does not exceed 3,000 μg (3 mg). to determine iodine content, revealing a minimum concentration of 660 μg/L (0.66 mg/L) and a maximum concentration of 31,000 μg/L (31 mg/L) [16]. Japanese iodine intake exceeds that of most other countries, primarily due to substantial seaweed consumption. Seaweeds have the unique ability to concentrate iodine from the ocean, with certain types of brown seaweed accumulating over 30,000 times the iodine concentration of seawater [9]. Seaweed grows on the floating netsand farmers (seaweed farmers) work on these plantations from their boats.

TZ acquired and compiled data shown in this study, interpreted data, and provided intellectual content. 2016, 36, 669–682. That said, the heavy metal content in seaweed is usually below the maximum concentration allowances in most countries (55). 10.1089/105072503322238827, Greer MA, Astwood EB: The antithyroid effect of certain foods in man as determined with radioactive iodine.

In 2002 the age-adjusted rate of prostate cancer in Japan was 12.6 per 100,000, while the US rate was almost ten times as high [44]. The algae are produced on the sea farms. In this reaction, iodine acts as both an iodinating reagent and a Lewis acid catalyst. [3] In Utsubo Monogatari, written around 987, nori was recognized as a common food. Nori ‘sheet’ form was first created in the early 18th … Sci Total Environ 1997, 204: 215–221. and purple (Porphyra sp.) J Radioanal Nucl Chem 2004, 259: 505–509. It’s the main carotenoid found in brown algae, such as wakame, and it has 13.5 times the antioxidant capacity as vitamin E (21). Today, nori (Porphyra spp., eg, Porphyra tenera, Porphyra pseudolinearis, and Porphyra yezoensis) is one of the most ubiquitous of the seaweeds used for human consumption in East Asia.According to the … Correspondence to This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/2.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The difference between wet and dry weight, along with the type of seaweeds being consumed, can result in extreme overestimation (more likely) or underestimation (less likely) of Japanese iodine intake.

Several grades of nori are available in the United States. In China and Japan, there are 7 main species used in commercial cultivation (Porphyra yezoensis, Porphyra tenera, Porphyra haitanensis, Porphyra pseudolinearis, Porphyra kunideai, Porphyra arasaki, and Porphyra seriata). Certain species of seaweed can concentrate bromine, a halide similar to iodine with no known physiological function, at very high levels [58, 59]. Kathleen Baker was hailed as the "Mother of the Sea" in Japan and a statue erected in her memory; she is still revered as the savior of the Japanese nori industry. Nori (laver, Porphyra yezoensis or Porphyra tenera) is red seaweed,mainly produced in Japan, China and Korea. ... especially iodine -in all seaweeds. Br J Cancer 1991, 63: 963–966. Porphyra is a coldwater seaweed that grows in cold, shallow seawater.More specifically, it belongs to red algae phylum of laver species (from which comes laverbread), comprising approximately 70 species. 10.1089/thy.2004.14.836, Nagataki S: The average of dietary iodine intake due to the ingestion of seaweeds is 1.2 mg/day in Japan. 10.1089/thy.2006.0209, Miyai K, Tokushige T, Kondo M, Iodine Research Group: Suppression of thyroid function during ingestion of seaweed "Kombu" (Laminaria japonoca) in normal Japanese adults.

Interpreting information to determine Japanese seaweed consumption and resulting iodine intake is a difficult task, and with ever changing diets, a close estimate is all that can be made.
