“…Hunt and Eales (1979) found that 84% of plasma iodine in rainbow trout came from water, 16% from the diet, and less than 1% from thyroid hormone degradation. Iodine content of marine fish is typically higher than that of freshwater fish and has been reported to vary from 50 to 560 mg/100 g meat (Eckhoff & Maage, 1997). AF muscle contained higher saturated fatty acids (palmitic and stearic acid) and LA content than did RH muscle (Po0.05, Table 1).…”

“…Iodine content of AF and RH mince was 12.6770.3 mg/100 g and 12.8370.1 mg/100 g, respectively. Eckhoff and Maage (1997) found that iodine content of catfish flesh in the East and West Greenland was 7.8 mg/100 g meat. Some variations in iodine content were influenced by age, diet, and habitat of fish.…”

“…Globally, 740 million people suffer from iodine deficiency, including up to 300 million with goiter and 20 million with brain damage from maternal iodine deficiency during pregnancy (Mu¨ller & Krawinkel, 2005). Iodine content of freshwater fish fillet was about 37.5 mg/100 g meat, which was about 5-10 times lower than that of marine fish (Eckhoff & Maage, 1997;Haldimann, Alt, Blanc, & Blondeau, 2005). Nutritional quality of processed food made from freshwater fish could be improved with the fortification of iodine.…”

“…Although iodine deficiency and use of polluted drinking water could be considered as causative factors of endemic goitre in these villages, consumption of cassava may be an additional factor producing important epidemiological variations. Cassava is widely cultivated and consumed on a large scale in villages of Lotte and Kodowono (16). However, boiling cassava roots is less effective in detoxifying the roots as compared to fermentation process.…”

Objective: To determine the magnitude of goitre in school children and measure indicators of iodine deficiency including the most commonly consumed staple foods. Design: A cross-sectional study. Setting: Ten villages from four administrative regions of Ethiopia. Subjects: A total of 2485 randomly selected elementary school children were examined for clinical signs of goitre. Indicators of iodine deficiency disorders (IDD) assessed were urinary iodine excretion (UIE) rate, iodine concentration in water, the commonly consumed individual foods of plant origin and milk, and bacterial contamination of drinking water. Results: The gross prevalence (mean of male and female values) among school children was 53.3%. The prevalence was higher in females (56.1%) than in males (50.8%). The highest prevalence (82 and 91%, respectively) were observed in the villages of Lotte and Kodowono and the lowest (31%) in the village of Abossara. Of the urinary measurements, 70% of the samples showed moderate and 30% mild iodine deficiency. Levels of iodine in water and individual food samples were low in general. Breast milk iodine content was similarly low and related to the maternal daily iodine intake which may affect the nutritional status of the nursing infant. The study also provides further evidence that coliforms and E. coli isolated from drinking water contribute to the high incidence of endemic goitre other than iodine deficiency. Conclusion: It is difficult to obtain a sufficient iodine intake in the survey villages as the individual foods are very low in the element. However, IDD can be prevented by ensuring normal iodine nutrition through instituting ways that avail iodinated salt to the survey population.

“…Iodine is an important micronutrient element and is required for the synthesis of thyroid hormones, thyroxine and triiodothyronine, which are iodinated molecules of the amino acid tyrosine. Seawater fish and other marine foods are frequently regarded as the most important natural source of dietary iodine, but there is little knowledge about freshwater fish (Eckhoff and Maage 1997;Belitz et al 2001). The daily intake of iodine recommended by the National Research Council of the US National Academy of Sciences in 1989 was 40 mg/day for young infants (age 0Á6 months), 50 mg/day for older infants (age 6Á12 months), 60Á100 mg/day for children (age 1Á10 years), and 150 mg/day for adolescents and adults (National Research Council 1989).…”

Two bivalve's species (Chamelea gallina and Donax trunculus) were investigated in terms of proximate and mineral compositions (sodium, potassium, magnesium, calcium, iodine and selenium) throughout the year. The concentrations of minerals were determined using inductively coupled plasma mass spectrometry. Ranges of moisture, protein, fat, ash and carbohydrate contents were 82.70-86.57%, 6.86-8.99%, 0.58-1.20%, 2.44-2.95% and 2.70-4.50% for C. gallina, and were 81.09-85.55%, 8.13-10.61%, 0.69-1.33%, 3.19-4.06% and 2.31-3.18% for D. trunculus, respectively. The highest sodium, potassium, magnesium, calcium, iodine and selenium contents for two species were found in the summer, followed by spring, autumn and winter. The concentrations of metals in two tissues exceeded the acceptable levels for a food source for human consumption.
