Re: interactions between selenium and iodine
He had(has?) a radio show called "Dead Doctors don't Lie"... :) I remember him talking about the nutrients in chicken skin & that's about it...
Anyway, the selenium & age spots thing, yup, here, too:

"Besides using PABA internally, other nutrients help protect the skin from sun damage from the inside out. The most important are likely essential fatty acids (EFAs). Using an EFA supplement may help minimize the skin damage which can lead to later problems. Equally important is avoiding damaged oils in the diet such as hydrogenated oils (margarine and many processed foods) and trans fats (fried foods).
Other nutrients which may provide a protective effect are minerals like selenium, and antioxidants. Selenium is included in sufficient amounts in most good multivitamins , or just eat two brazil nuts per day, the richest natural source. After ensuring that sufficient basic antioxidants are being consumed such as vitamin C and mixed tocopherols, one can look to the superantioxidants such as curcumin, grape seed extract, alpha lipoic acid, and many others. A good combination product to add additional antioxidants is Now Super Antioxidant."
