Hi!

Recently i've been thinking a lot of selenium and iodine after listening to Chris Kresser's podcast.

I live in Scandinavia(Sweden) where we often get too little selenium through the foods we eat.

What i have read so far is that Brazil nuts contains very high amounts of selenium, although some sources say its like 50 ug for 100 grams and some say it's as high as 200 ug per nut!

Can someone shed some light on this?

Does it matter from where the brazile nuts are coming from, or are they similar?

If i were to suplement, how much and what type of selenium should i go for?

I have my patients eat the evolutionary package, IE seafood over a supplement all the time. Brazil nuts also have Se in it.

Homemade lard is a good source of selenium with 0.2 mg/100 g.

Selenium levels in (land based) foods vary geographically, depending on the soil content. http://www.wellnessletter.com/ucberkeley/dietary-supplements/selenium/

The amount of selenium in Brazil nuts depends on the selenium content of the soil where the trees grow. http://www.scientificpsychic.com/blogentries/brazil-nuts-a-variable-source-of-selenium.html

You could try 'google images' for something like 'selenium soil' for some geographic maps showing selenium soil content. & throw in a location you are interested in to further refine the query.

Here are a couple of good sites which detail Selenium food sources; 1. excluding Brazil Nuts, 2. including Brazil nuts
