Hi Mike,

Sorry for the delayed response; I don’t check back on these blog posts too often. 🙂 I want to commend you for such a great catch! Typically, I don’t recommend more than 5 Brazil Nuts per day, given the high amount of selenium found in this food. I noticed there is a bit of discrepancy in nutrient information between 1/4 cup and 5 Brazil nuts (i.e. calories are higher in the latter reference amount, but selenium intake is lower). However, to avoid confusion and err on the side of caution, I have asked the team to remove Brazil nuts as a source of magnesium in the above table.

Thanks again for reporting this!

Kind regards,

I find it disturbing that this article seems to suggest that 1/4 cup of brazil nuts is an acceptable daily serving. Using Cronometer, I find that 1/4 cup of Food #451463, Data Source: NCCDB has 637 mcg of selenium. Do you want to recommend that anyone regularly consume nine times the daily value? If so, is there good reason to believe the FDA has erred when it set the DV?
The tolerable upper intake level is often accepted to be 400 mcg. This article should either be revised or an explanation should be added since it has the potential to advise people to do something that could be harmful. I recognize that it has come from the Dietitians of Canada, all the more reason to view it critically. If you want to delete my comment, feel free, as long as the offending reference is removed.
