Brazil nuts (Bertholletia excelsa) are large Amazonian tree seeds with the highest selenium concentration of any commonly eaten food, though actual content varies widely by growing region. Per 100g, they provide 659 kcal, 67.1g fats (24.6g MUFA, 20.6g PUFA, 16.1g saturated), 14.3g protein, and a lab-average 1,917µg selenium (3,485% DV) -- a handful per day is a sensible ceiling, not a target.
