Supposedly even just 1 per day will prevent you from being deficient in Selenium - I would just eat them as directed per serving size - I'm assuming this is a few nuts or around 1/4 cup. I actually use an old pre-workout jug and I fill it every month with raw nuts from Trader Joes. I'll pop in almonds, brazil nuts, cashews, pepitas, shelled pistachios you name it.
