A coworker of mine introduced me to Nutritionfacts.org. There is an article called Four Nuts Once a Month by Dr. Greger. I started eating 1 Brazil nut every day (even though the article said you would get the same results eating 4 nuts a month).
My results are as follows: I went from 224 down to 204 down to 136. I get mine already shelled at Trader Joes. They will always be a daily staple of mine. Brazil nuts are high in selenium.
