The Claim
Daily consumption of two Brazil nuts for 12 weeks increases whole blood glutathione peroxidase activity by 13.2% in healthy adults, and this increase is greater than that observed with an equivalent dose of selenomethionine.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating two Brazil nuts every day for 12 weeks raises glutathione peroxidase activity in the blood by 13.2% in healthy adults, more than taking the same amount of selenium as selenomethionine.
See the scientific wording
Daily consumption of two Brazil nuts increases whole blood glutathione peroxidase activity by 13.2% over 12 weeks in healthy adults, a greater increase than observed with an equivalent dose of selenomethionine, suggesting Brazil nuts may enhance selenium-dependent antioxidant activity more effectively than isolated selenium compounds.
Selenium from Brazil nuts is absorbed in the gut, converted into a form that the body uses to build a key antioxidant enzyme called glutathione peroxidase, and this enzyme becomes more active in the blood, where it neutralizes harmful molecules that damage cells.
What the research says
1 studyStudy: Brazil nuts: an effective way to improve selenium status.
Eating two Brazil nuts every day for three months raised a key antioxidant enzyme in the blood more than taking a selenium pill, showing the nuts might be better at boosting the body’s natural defenses than the supplement.
