Seaweeds iodine content

Seaweed is a primary source of iodine, and in some seaweed, iodine content exceeds its dietary minimum requirement (150 pg/day). The highest iodine content is found in brown algae (1500-8000 ppm), and in most instances, red and green algae have lower contents. Iodine amount in the seaweed remains comparatively high than that in the land plants. Since animal- and plant-derived foods are very low in iodine, seaweeds can be considered as the best inexpensive food to fulfill the iodine requirement of human. [Pg.21]

Iodine is mainly found in marine material. Salt water fish, shellfish, and seaweed are food sources with the highest natural iodine content. Seaweed has a very high iodine content one bowl of soup made by tangle, which is a common soup... [Pg.333]

The iodine intake of vegans participating in the Rauma investigation was extremely low, despite the consumption of seaweed, although the levels of serum T4 and TSH were within the normal range (Table 45.4), indicating normal thyroid function, and the urinary iodine excretion level was high (Table 45.5). The difference in dietary iodine intake and biochemical measurements was attributed to the use of seaweed and seaweed products with unknown iodine content. [Pg.434]

Notes Concentrations of iodine vary wideiy among seaweed species, with brown aigae showing the highest iodine ieveis. in addition, iodine content in seaweeds underiies geographic and seasonai variations. [Pg.899]

Sources. The iodine content of most foods depends on the iodine content of the soil in which it was raised. Seafood is rich in iodine because marine animals can concentrate the iodine from seawater. Certain types of seaweed (e.g., Undaria pinnatifida or wakame) are also very rich in iodine. Processed foods may contain slightly higher levels of iodine due to the addition of iodized salt or food additives, such as calcium iodate and potassium iodate. ... [Pg.268]

Edible seaweed products have become popular in the food industry, especially in Japan. Elements of 15 seaweed samples collected on the coasts of British Columbia (Canada), Japan, and Norway were analyzed, and the radioactivity were measured. The iodine content of algae was found to vary widely, with the highest concentrations in wakame from Japan. The analysis shows little activity above background only traces of Cs were found in a product from Norway, and traces of Ra were found in a product from Japan. Arsenic levels are found to be elevated (van Netten et al., 2000). [Pg.2519]

Iodine occurs in traces in most foods and is present mainly as inorganic iodide, in which form it is absorbed from the digestive tract.The richest sources of this element are foods of marine origin, and values as high as 6 g/kg DM have been reported for some seaweeds fishmeal is also a rich source of iodine. The iodine content of land plants is related to the amount of iodine present in the soil, and consequently wide variations occur in similar crops grown in different areas. [Pg.128]

Iodine-containing seaweed is widely consumed in Japan, and to a lesser extent in other industrialized countries. The iodine content differs considerably among kelp species. In Hokkaido daily ingestion of over 100 mg iodine as kelp has been reported (11). Iodine in the Japanese diet can vary widely from day to day depending on the inclusion of kelp. [Pg.23]
