- Selenium Provides Powerful Antioxidant Support
Another reason Brazil nuts have attracted scientific interest is their influence on the body’s antioxidant defenses.
Selenium is incorporated into glutathione peroxidase and other antioxidant enzymes that help protect cells from oxidative damage.
The randomized study using two Brazil nuts daily found increased glutathione peroxidase activity as selenium status improved.
A broader systematic review of Brazil nut clinical trials also found improvements in selenium status and/or glutathione peroxidase activity across studies assessing antioxidant status.
Supporting antioxidant defense may be particularly relevant because oxidative stress is associated with aging and numerous chronic diseases.
That doesn’t make Brazil nuts a “detox” treatment—but it does make them an extraordinarily concentrated source of an important micronutrient.
How Many Brazil Nuts Should You Eat?
With many healthy foods, more is often fine.
