Special Issue Information

Dear Colleagues,

Eating behaviour is influenced by a complex interplay of physiological, psychological, socio-economic, and genetic factors. It plays a crucial role in determining food intake, impacting overall health, and contributing to the development of chronic diseases like diabetes, cardiovascular disease, and obesity. Various elements, including education level, cultural background, personal experiences, sensory ability, and socio-economic factors like gender, age, and smoking, shape eating behaviour. Genetics also contribute, supported by twin studies, genetic association studies, and genome-wide association studies. A comprehensive understanding of both genetic and non-genetic factors influencing eating behaviour can help in developing personalised strategies for promoting health.

In this Special Issue of Nutrients, we encourage the submission of manuscripts focused on the factors influencing eating behavior and the impact of these factors on health status.

We aim to gather new information in this field and include it in this Special Issue. We invite researchers to contribute original and unpublished research and review articles on this topic.

You may choose our Joint Special Issue in Foods.

Abstract
Background/Objectives: The TAS1R2 SNP rs35874116 has previously been associated with sweet taste, diet, and health status, although never comprehensively in a single study. Also, associations between TAS1R2 and sweet taste might be body mass index (BMI)-dependent. Therefore, this study aimed to conduct a [...] Read more.
Background/Objectives: The TAS1R2 SNP rs35874116 has previously been associated with sweet taste, diet, and health status, although never comprehensively in a single study. Also, associations between TAS1R2 and sweet taste might be body mass index (BMI)-dependent. Therefore, this study aimed to conduct a comprehensive investigation of rs35874116 and sweet taste intensity and liking, food liking, and diet and health status whilst considering BMI. Methods: Five-hundred and fifty-four participants were recruited. Linear regression models were used to explore rs35874116 associations with sweet taste intensity and liking, food liking, and diet and health status. A secondary analysis stratified participants by BMI <25/≥25 kg/m2. Results: The rs35874116 wildtype was associated with increased sweet taste intensity (p = 0.0345, B 1.29, SE 0.61) and liking (p = 0.021, B 0.25, SE 0.11). However, these associations only remained in BMI ≥25 individuals (intensity: p = 0.037, B 1.29, SE 0.61, liking: p = 0.008, B 0.46, SE 0.17). It was also associated with decreased diet quality (p = 0.03, B −0.27, SE 0.13) and reduced free sugar consumption but increased saturated fat consumption in BMI ≥25 individuals (free sugars: p = 0.0416, B −0.8, SE 0.38, saturated fat: p = 0.031, B 1.38, SE 0.62). There was no association with the mean liking score for sweet foods, although there were some associations with individual foods, which require further investigation. There were no associations with health status. Conclusions: This study revealed an association between the rs35874116 wildtype and an increased intensity and liking of the sweet taste and a corresponding worse overall dietary quality. This study adds to previous evidence regarding how associations between TAS1R2 and sweet taste are BMI-dependent. Full article
