Daily Brazil nuts for selenium
DeLauer explains that even a daily decline in selenium reduces phase 2 detoxification significantly. He underscores that glutathione peroxidase is produced by the liver and serves as the master antioxidant. Brazil nuts pack a potent selenium punch, making them a convenient, food-based way to maintain this pathway. He contrasts them with his usual nut preferences (macadamias) due to the unique benefit.
Selenium is a critical cofactor for glutathione peroxidase, which reduces hydrogen peroxide to water, enabling excretion. When selenium is insufficient, this antioxidant defense weakens, leaving liver cells more vulnerable to oxidative damage.
People do not realize that glutathione peroxidase the main primary antioxidant that we produce the master antioxidant in our body produced by the liver is selenium dependent. So the moment that selenium levels go down even on the daily our ability to have this phase 2 detoxification goes down significantly.
