“…Moreover, based on associations between dopamine and curiosity and information-seeking 4,5,26,28 , we explored whether trait curiosity and information-seeking could predict the daily intake days later of large neutral amino acids (LNAA) tyrosine-and phenylalanine (i.e. precursor for dopamine), and tryptophan (precursor for serotonin) relative to other LNAAs 32,33 . We extracted the quantity of macro-and micro-nutrients including LNAAs from the submitted food in the food-diary app (see Methods).…”

The COVID-19 pandemic confronted humans with high uncertainty and lockdowns, which severely disrupted people’s daily social and health lifestyles, enhanced loneliness and reduced well-being. Curiosity and information-seeking are central to behavior, fostering well-being and adaptation in changing environments. They may be particularly important to maintain well-being during the pandemic. Here, we investigated which motives drive information-seeking, and whether and how curiosity and information-seeking related to well-being and mood (excitement, anxiety). Additionally, we tested whether daily diet contributed to this relationship during lockdown. Participants (N=183) completed questionnaires measuring curiosity, information-seeking, social and mental health. Using a smartphone app, participants submitted their daily food intake and lifestyle ratings for a week. We found participants had highest motivation to seek positive (vs. negative) information, concerning themselves more than others. Both trait curiosity and information-seeking predicted higher well-being, by reduced loneliness. Trait curiosity also predicted well-being and excitement days later. Considering diet, people with lower curiosity consumed food high in dopamine precursor tyrosine, whereas high-sugar intake increased anxiety, only in people with relatively low, but not high, trait curiosity. Taken together, curiosity and information-seeking may benefit well-being and mood in high uncertain and challenging times, by interacting with lifestyle measures (loneliness and nutrition).

“…Previous work has also linked a BMI to impulsivity, and a higher body fat assessment (BFA) has been associated with risky decision making 64 . As exploration involves more risk‐taking, 18 a higher BMI/BFA may, thus, be more strongly associated with exploratory rather than exploitative behavior 65 . Therefore, it may be recommended that future studies investigating exploratory food choices also take body indices or other measures of risk‐taking into account.…”

With limited resources, exploring new opportunities is crucial for survival. Exploring novel options, however, comes at the cost of uncertainty. Therefore, there is a trade-off between exploiting options with a known beneficial outcome and exploring novel options with a potentially higher gain. Computational models have suggested that novelty may promote exploratory behavior by inducing a so-called novelty bonus through reward-related processes. So far, few studies have provided behavioral evidence for such a novelty bonus. In this study, we aimed to investigate whether spatial novelty can stimulate exploratory behavior (Experiment 1), and whether age, novelty-seeking, and reduced action radius or social interactions due to COVID-19 restrictions influenced the exploration-exploitation trade-off (Experiment 2). In both experiments, we employed a novel paradigm in which participants made binary decisions between food items, while on rare trials, a surprise option was presented. Results from Experiment 1 are in line with a novelty bonus, with spatial novelty promoting exploratory behavior. In Experiment 2, we found that exploratory behavior declined with age, high novelty seekers made more exploratory choices than low novelty seekers, and participants with a smaller action radius made fewer exploratory choices. These findings are consistent with previous findings in animals and predictions from computational models.
