I'm hypothyroid and know that getting the right amount of selenium is important for my metabolism. And I noticed today that you're featuring a Health article emphasizing that too little, or too much, selenium is bad for you.
One of the ways I get selenium is to eat brazil nuts, about one a day about 4 times per week. But I had to create my own entry for brazil nuts because the SP default entry for brazil nuts doesn't contain any of the details on minerals like selenium. Brazil nuts can contain as much as 500 micrograms of selenium (about 700%) of recommended daily value, but SP lists the selenium value as 0! If someone is trying to take the appropriate amount of selenium (by eating foods with selenium like brazil nuts) and is using SP's nutritional information, she could easily end up taking too much because your entry is inaccurate.
I posted a similar comment several months ago and no one has fixed the problem.
