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.
