[QUOTE="Travlr, post: 1798445, member: 42463"] How much of that 1 1/4 ounces comes from normal eating... even in selenium "deficient" areas? An ounce is a very large amount for a trace mineral. Brazil nuts have 544 mcg selenium per ounce. Regardless of where you live, beef cattle require a minimum of 0.1 ppm of selenium in their daily diet [National Research Council (NRC) recommendation]. For a mature cow [1,400 pound (lb.)], that is an intake of about 1 milligram (mg) of selenium per day. One milligram is a lot less than an ounce. And too much selenium has detrimental effects, too. One milligram is .00003527 of an ounce. [/QUOTE]
