Iodine Deficiency, an example from Sri Lanka
10 million
- partially successful
iodized salt
programs have
been introduced
study: : soil and rice samples collected from 15 villages in Sri Lanka
- total iodine concentrations in the soil were the same in
highly iodine deficient villages as in less iodine deficient - highly deficient areas the
iodine was adsorbed onto oxide minerals and organic matter in the soils, making it unavailable for plant uptake
what is better at iodine uptake
green leafy vegetables
what is worse at at iodine uptake
rice, bigger diet there
