  • Data from Belgium reveal that patients with zinc and selenium deficiencies, especially those with comorbidities associated with worse COVID outcomes, had a higher risk of mortality and severe disease
  • Up to 1 billion worldwide may be deficient in selenium with symptoms that can include hair loss, fatigue, weight gain, immune system and cognitive decline
  • Zinc deficiency may affect up to 2 billion worldwide and may be responsible for more than 450,000 deaths every year in children younger than 5 years. Signs of deficiency may include, weak immunity, lack of appetite, hair loss, acne and a loss of taste and smell
  • The role of zinc in the fight against coronaviruses has been known since at least 2010; zinc requires help getting into the cell to fight viruses. Although hydroxychloroquine is effective, new data show quercetin may have the same function, while being less expensive and more easily obtained
  • Choose foods high in zinc and selenium, including pasture-raised beef or chicken, pasture-raised eggs, pumpkin seeds, Brazil nuts and sardines
