Malabsorption is a state arising from abnormality in absorption of food nutrients across the gastrointestinal (gi) tract impairment can be of single or multiple nutrients depending on the abnormality.
Hycrete testing summary salt leaching was observed through the control and not absorption test demonstrates up to six times lower absorption. The iodine in salt is also quite low, and it is in a form that has a very low absorption rate on top of that (only about 10% is absorbed) (only about 10% is absorbed) essentially, the amount of iodine in table salt is just enough to prevent a condition of enlarged thyroid gland called goiter.
