No, not brazil nuts. The amount of selenium in brazil nuts is highly variable, and sometimes it's just plain high. Dangerously so. Better to control the dosage with a pill and a food diary that tracks selenium. (I track all my nutrients from food so I don't over-supplement, and I never eat brazil nuts.)

I don't tend toward high blood sugar, btw. When my endo stuck the Dexcom on me, my results were pretty scary--I was going into the 40s while I slept, and I wasn't getting very good glucose levels during the day either. It's better now, though. I feel very lucky to have been accepted into the metformin trial, because I was afraid hypoglycemia would be cause for rejection.
