Beneficial effects on body weight of supplementation with BCAA, including leucine, isoleucine, and valine, have been observed in animal and human studies.
The objective of this study was to examine the association between dietary BCAA intake and risk of overweight status/obesity among multi-ethnic populations.
The International Study of Macro-/Micronutrients and Blood Pressure is a cross-sectional epidemiological investigation in China, Japan, the UK, and the US. The study cohort included 4429 men and women ages 40–59 years who were free of diabetes.
Diet was assessed by 4 multi-pass 24-hour recalls; data on nutrients including BCAA were derived from country-specific food tables.
Overweight status and obesity were defined as BMI = 25 and BMI = 30 kg/m2, respectively. Multivariable-adjusted OR of overweight status/obesity and 95% CI by quartiles of BCAA intake were estimated by logistic regression.
BCAA intake and obesity were also inversely associated. In conclusion, higher dietary BCAA intake is associated with lower prevalence of overweight status/obesity among apparently healthy middle-aged adults from East Asian and Western countries.
