What is the link between personality and food behavior?
According to multiple works in sensory science research, people divide into three groups: supertasters, medium-tasters, and non-tasters. There is some evidence that supertasters exhibit more food dislikes, also being more apprehensive, tense, and imaginative than non-tasters. Experiencing different tastes has been shown to affect people's mood, their perception, and their behavior. Interestingly, the most anxious individuals are the least willing to trying novel foods. Taken together, the evidence published to date supports that personality-based differences in taste perception and food behavior are linked to differences in circulating levels of neurotransmitters and hormones. A bidirectional connection has also been found between taste and mood. Nonetheless, making specific food preferences linked to particular personality is still studied. The fact that foods have changed over the decades and also vary greatly by culture, makes it difficult to research.
