The Claim

Nuts, cooked fish, and boneless meat are the top three dietary sources of selenium in Brazilian adults, collectively contributing 45.3% of total selenium intake, with nuts alone accounting for 28.9% of intake, indicating that animal products and tree nuts are the primary contributors to selenium nutrition in this population.
