The acute effects of caffeine and polyphenols on mood havebeen studied extensively, but the impact of chronic consumption of caffeine andpolyphenols on mood needs further exploration. Polyphenols act via several mechanisms in the brain, which may impact cognitive and mental health. Long‐term consumption of polyphenols may enhance neuroplasticity and present an exciting possibility for using diet as a viable method of battling cognitive and psychiatric disorders. Vast literature has examined behavioral effects of single doses of caffeine however, this is not representative of caffeine consumption patterns. The purpose of this exploratory study was to examine the relationship between self‐reported chronic polyphenol and, caffeine consumption and mood. A convenience sample (n=561, males= 329, females=232, age=21.21±4.869yrs, height=173.13 ±10.98cm, weight=76.44 ±18.07kg) from a small town in upstate NY was surveyed. A 30‐day food frequency questionnaire was used to determine polyphenol consumption, a 30‐day caffeine consumption questionnaire was used to determine caffeine consumption and the Profile of Mood Survey(POMS) was used to determine mood. Polyphenol consumption was divided into fruit, vegetables and polyphenol containing beverages. Caffeine consumption was divided into energy drinks and total caffeine consumption. A Pearson bivariate correlation analysis revealed a small positive relationships between POMS vigor scores and consumption of caffeine (r=.124; p=.004), vegetables (r=.096; p=.041), fruit (r=.154; p=.001), and total polyphenol consumption (r=.158; p=.001,). Significant positive relationships were also found for POMS anger scores and energy beverage consumption (r=.087; p=.043) as well as POMS tension scores and caffeine consumption (r=.092; p=.033). There was a small negative relationship between POMS fatigue scores and vegetable consumption (r=‐.115; p=.013) Findings suggest that chronic polyphenol consumption may increase feelings of vigor. Vegetable consumption may reduce feelings of fatigue and energy beverage consumption may increase feelings of anger. Caffeine yielded mixed results; consumption may increase levels of vigor yet also provoke feelings of anxiety and tension. Smallr values suggest that these relationships are minor. Further, it is unclear whether an individual's mood state drives nutritional choices or vice versa. Future research should investigate the quantity of polyphenols within subjects’ diet as well as exploring the causal nature of these relationships among larger, more diverse populations.
