Best source of selenium?

Brazil nuts are the best dietary source of selenium, according to Andrew Huberman. Consuming just six to eight Brazil nuts can provide about 550 micrograms of selenium, which is significantly higher than other food sources. Selenium is also found in fish, ham, beef, turkey, chicken, cottage cheese, eggs, and brown rice, but in much smaller amounts compared to Brazil nuts. It's important to be cautious with the intake of selenium from Brazil nuts due to their high concentration, as excessive consumption can lead to potential health issues. Always consult with a healthcare provider before making significant changes to your diet 1.
