Gut health, the microbiome and dietary choices: An exploration of consumer perspectives

Food4healthKG: Knowledge graphs for food recommendations based on gut microbiota and mental health

Food is increasingly acknowledged as a powerful means to promote and maintain mental health. The introduction of the gut-brain axis has been instrumental in understanding the impact of food on mental health. It is widely reported that food can significantly influence gut microbiota metabolism, thereby playing a pivotal role in maintaining mental health. However, the vast amount of heterogeneous data published in recent research lacks systematic integration and application development. To remedy this, we construct a comprehensive knowledge graph, named Food4healthKG, focusing on food, gut microbiota, and mental diseases. The constructed workflow includes the integration of numerous heterogeneous data, entity linking to a normalized format, and the well-designed representation of the acquired knowledge. To illustrate the availability of Food4healthKG, we design two case studies: the knowledge query and the food recommendation based on Food4healthKG. Furthermore, we propose two evaluation methods to validate the quality of the results obtained from Food4healthKG. The results demonstrate the system's effectiveness in practical applications, particularly in providing convincing food recommendations based on gut microbiota and mental health.

A Translational Approach to Increase Pulse Intake and Promote Public Health through Developing an Extension Bean Toolkit

Practical, affordable solutions need to be implemented to address global challenges confronting human and environmental health. Despite a myriad of benefits for people and the planet, beans and other pulses (e.g., chickpeas, cowpeas, dry peas, lentils) are under-consumed. To better understand consumer concerns and interests, a Food Habits Survey was conducted and the findings were incorporated into the Colorado State University Extension Bean Toolkit. Guided by the Information-Motivation-Behavioral Skills model, the toolkit included informational social media posts, cooking guidance, and an online class. A convenience sample of participants was recruited through Extension and university networks. After class participation, significant gains in knowledge of pulse nutrition, versatility, and cooking were observed, with an average increase of 1.5 points on a 5-point Likert scale (p < 0.001). Moreover, participants (n = 86) perceived a greater importance of motivators (e.g., nutrition, versatility, environmental benefits) and found barriers (e.g., flatulence, long cooking times, unfamiliarity) to be less discouraging. Most participants reported an intention to eat more pulses, and among those who completed the 1-month follow-up survey, pulse intake frequency increased (p = 0.004). Emphasizing motivating factors while simultaneously mitigating barriers to consumption can help reverse insufficient intake and promote healthy behavior change. Leveraging Extension or similar networks is one way to adopt a translational approach to better reach the public with this information.
