My geologist brother told me a few years ago to take daily selenium supplements. He said our soil is not as mineral-rich as it used to be so we can’t get it from food alone.

Depending on where you live the soil may be naturally low in selenium.

I have to give it to our cows to keep them healthy.

Seems to correspond to where the glaciers used to be. Was your land covered in ice 10,000 years ago? Probably low in selenium.

Be Careful with Brazil Nuts and Selenium Poisoning

"If you eat too many Brazil nuts, you may end up suffering from selenium poisoning. Brazil nuts are rich in selenium, and there is about 544 mg of selenium in 1 ounce of serving. Selenium is a micronutrient that is required by the body only in trace amounts. It is essential to the body for the production of selenoproteins which are enzymes that play a major role in the regulation of the immune system and the thyroid gland.
