Iodine status of food and drinking water of a sub-Himalayan zone of India

Abstract

Iodine content of rice (42) and drinking water (108) from a goitre-endemic belt of Assam, a sub-Himalayan zone of India, was evaluated. Iodine content of staple food (rice) and drinking water was found to be poor. Mean iodine content of rice was found to be 11.8 +/- 7.3 micrograms/100g. Lower level of iodine was also observed in drinking water samples (mean of 1.52 +/- 0.48 micrograms/l).

Determination of Iodine Nutrition and Community Knowledge Regarding Iodine Deficiency Disorders in Selected Tribal Blocks of Orissa, India

“…Rainwater returns iodine to the soil and has iodine levels in the range of 1.8-8.5 μg.Γ l . The results revealed environmental iodine deficiency, which is in agreement with earlier studies that populations in mountainous regions with subsistence economy cannot improve iodine intake by diversifying their diet 28 . Coastal areas have more iodine in water sources than mountainous areas, because iodinerich soil is swept away by heavy rains and replaced by new soil derived from iodine-poor crystalline rocks'.…”

Iodine content of water and foodstuffs from different agroclimatic zones of Haryana State, India

“…It has been reported that the average iodine concentration in underground drinking water from China was more than 300 μ g/l (Zhao et al , 1998) and that drinking water from the sub‐Himalayan zone of India contained 1.52 μ g/100 ml±0.48 μ g iodine/l (Sharma et al , 1999).…”
