Research reveals a significant link between coffee consumption and skeletal muscle mass among U.S. adults. This study utilized data from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018, focusing on how coffee and caffeine intake affects muscle mass. The findings suggest that higher coffee consumption is correlated with increased appendicular skeletal muscle mass, particularly in individuals with a normal body mass index.
• A total of 8,333 participants were analyzed, showing that coffee intake positively affects skeletal muscle mass.
• The study found that both coffee and caffeine consumption were linearly associated with increased appendicular skeletal muscle mass.
• Subgroup analyses indicated that age, gender, and ethnicity did not significantly alter these positive relationships.
• However, the benefits of coffee consumption on muscle mass diminished in individuals with a body mass index over 30 kg/m².
Understanding the relationship between coffee intake and muscle mass is crucial, especially for individuals at risk of low muscle mass. Encouraging moderate coffee consumption could be beneficial for enhancing muscle health in these populations.
