Hankjam beat me to it. 1 or 2 nuts a day gives you your total selenium. Selenium is one of the nutrients you are supposed to be careful not to get too much. It's very abundant in tuna and salmon as well as a few other fish. The good news is it binds to Mercury and carries it out so far less fear of mercury when eating these fish.
I like mixing up a trial mix with different nuts and seeds. A little of this and that also gives me a variety of nutrients and allows for a few tastes do carb ire nuts.
