Abstract
BACKGROUND & AIMS: Although the mechanisms by which statins promote muscle disorders remain unclear, supplementation with dietary antioxidants may mitigate statins' side effects. This study aimed to investigate whether the consumption of Brazil nuts modulates serum creatine kinase (CK) activity in patients regularly using statins. METHODS: The study was performed in the Ribeirão Preto Medical School University Hospital. Thirty-two patients in regular use of statins were divided according to CK activity levels (G1: increased or G2: normal) and received one unit of Brazil nut daily for 3 months. Body composition, blood selenium (Se) concentrations, erythrocyte glutathioneperoxidase (GPX) activity, oxidative stress parameters, and CK activity were evaluated before and after supplementation. RESULTS: In both groups, supplementation with one Brazil nut daily for 3 months contributed to achieve decreased levels of CK activity in serum, with positive changes in plasma and erythrocyte Se concentrations (p
