The video I linked today talks about the need for iodine for cancer cell apoptosis (programmed death). I've never heard anything about this previously.

Iodine and cancer cells
"How much iodine is enough? It has been shown that daily doses of iodine above two to three milligrams per day (about half a drop from a standard eyedropper) saturate the thyroid within a couple of weeks. At this point, the thyroid gland stops taking up iodine. This means that at a dietary intake above two to three milligrams, all of the iodine goes to all its other functions in the body, such as killing off abnormal cells."
"Iodine remains the perfect antiseptic with the least side effects of all time. As a perfect antiseptic killing all single-celled organisms, there has to be a common mechanism of a single element like iodine. In fact, the reaction of iodine with tyrosine destroys the protein and consequently the cell itself. If, in vertebrates and multicellular organisms, the tyrosine molecule is hidden from the surface when it is normally functioning, the iodine will not trigger any apoptosis. However, during abnormal development, it could be that tyrosine or histidine molecules are slowly exposed to the surface. Extracellular iodine bathing the cells could then trigger the apoptotic mechanisms.
"The second phase of cancer spread involves thyroid hormone indirectly. The connective tissue barrier and function is controlled and strengthened by adequate levels of connective tissue thyroid hormone. Thus thyroid hormone controls the connective tissue barrier, and prevents the spread of cancer cells.
"Iodine in adequate doses prevents the development of cancer cells, and adequate thyroid hormone in the connective tissue prevents the spread."
