Calculation of Daily Selenium Intake

Following is the calculation You can understand why experts say to eat no more than 2 brazil nuts per day.

1 brazil nut provides 95.9 mcg selenium, which is greater than the recommended daily allowance of selenium per day.


Brazil nuts contain very high amounts of selenium (68–91 mcg per nut) and could cause selenium toxicity if consumed regularly, The Office of Dietary Supplements suggests.


Acceptable Upper Intake Levels of selenium for adults is 400mcg (Adults and children 14 and up) and 1 brazil nuts can have 95.9 mcg selenium. If we want to find ideal intake of brazil nuts than we should divide them to find the total number of brazil nuts we can eat.

To find the number,

How many brazil nuts a day=Upper intake level of selenium/Selenium content in 1   brazil nut=400mcg/95.9 mcg=4.17

The above calculation tells if we eat 4 brazil nuts we can stay by the acceptable upper intake level of selenium But the question is not how many we can eat, it’s how many we should eat.

To finding the ideal number of brazil nuts, we should take the recommended dietary allowances for Selenium, which is 55 mcg for the adult (Adults and children 14 and up).

That clearly, says if you eat 1 brazil nut, you will have enough selenium that you need for a day.

  1. This site has given me all the information that I wish I had learned many months ago. I have been over eating Brazil Nuts and have the symptoms mentioned. From now on I will eat only one a day starting from a weeks time. Enough time to bring the overdose down. I am 74 years, and believed I was doing well. Then I became a very cross person, and almost a recluse. I always new Brazil nuts were the best. I just didn’t know what an overdose of selenium can do to your body. I found this site after my sister, in the US, mentioned I must not eat too many Brazil Nuts!

  2. Although I knew there was an upper limit of how many Brazil Nuts you should eat, the number I was told was much higher than this article informs. I had Brazil nuts freely available on the counter and would eat 2-4 a couple times a day thinking the max number for toxicity was closer to 40. I don’t know where that information came from. I thought I would never reach that quantity and didn’t. My symptoms declined into violent diarrhea for over two weeks. I am only now reducing my symptoms but cannot stray too far without a restroom in sight. I’m hoping I have discovered the source of the problem.
