Human body odour is an important sexual attractant for potential partners. It is influenced by environmental factors, such as an emotional state and health. Important environmental factors influencing human body odour are also eating habits. However, we know very little about how particular dietary components shape our body odour. Only the effect of red meat and garlic consumption have been tested. Here we tested the effect of caffeine (from usual source and guarana) and beta- carotene. In our three experiments we used a balanced within-subject experimental design.

Results showed that caffeine consumption may influence negatively attractiveness and intensity of human body odour. Guarana and beta-carotene did not show any significant results.
