title: Lycopene status is not associated with insulin-like growth factor-1 concentration in a healthy male population.
abstract: OBJECTIVE
  The aim of this study was to assess the relationship between lycopene and insulin-like growth factor-1 levels in a healthy male population.
  
  
  METHODS
  Insulin-like growth factor-1 status was assessed in healthy men aged 30-49 years (n = 104) with either high or low lycopene concentrations.
  
  
  RESULTS
  There was no significant difference between insulin-like growth factor-1 levels in the high- and low-lycopene groups; high lycopene group; 8.21 (2.73) nmol/L; low lycopene group; 7.65 (2.14) nmol/L, p = 0.46 (Mean (SD)).
  
  
  CONCLUSIONS
  In this small observational study, no association was found between lycopene concentration and insulin-like growth factor-1 concentration.
