Selenium & Antioxidant Defense
Does selenium support longevity?
Selenium is vital for antioxidant defense and thyroid health, and both deficiency and excess can increase mortality.
Explanation
Selenium is required for selenoproteins like glutathione peroxidase, which protect against oxidative stress. Epidemiological studies link adequate selenium intake with reduced cancer incidence and lower cardiovascular mortality.
Practical Emphasis
Include selenium-rich foods in your diet but avoid excessive supplementation. Just a few Brazil nuts per week may be sufficient.
Action Tip
Maintain selenium intake in the optimal range for antioxidant protection and thyroid health.
