Selenium / Brazil Nuts
In RCTs, a decreased risk of all cause mortality was seen with antioxidant mixtures when selenium was part of the mix (RR: 0.90; 95% CI: 0.82, 0.98; P = 0.02). A single intake of Brazil nuts (20 or 50 g) caused a significant decrease in inflammatory markers such as serum IL-1, IL-6, TNF-α, and IFN-γ levels (P < 0.05). Improved lipid profile of healthy volunteers. Selenium supplementation decreased serum CRP (SMD = −0.48; 95% CI, −0.96 to 0; p = 0.049) and increased glutathione peroxidase (SMD = 0.5; 95% CI, 0.36–0.64; p < 0.001). Selenium supplementation inhibits IGF-1 signaling and confers methionine restriction-like healthspan benefits to mice. Selenium supplementation mitigates the toxic effects of environmental mercury, lead, arsenic, and cadmium by forming an insoluble complex (chelate) with these metals and reversing the oxidative damage. Selenium supplementation improved semen parameters in males. 2 Brazil nuts per day provide optimal intake (there is ...
