Analysis of the Perception of Nutrigenetics in Conventional Nutritional Practice: A Survey-Based Study Applied to Dietitians from Mexico.

BACKGROUND/OBJECTIVES: Nutrigenetics has emerged as a promising tool to advance personalized nutrition strategies. This study aimed to analyze the scope and perception of Mexican dietitians regarding nutritional genomics with an emphasis on nutrigenetics' use in clinical practice.

METHODS

A survey was conducted online among dietitians in Mexico to assess their educational background, awareness of nutrigenetic testing, use in practice, and interest in further training through 33 questions.

RESULTS

One hundred and thirty participants from states across six Mexican regions completed the survey, and most of respondents had a bachelor's degree. The analysis showed that while most respondents were familiar with the concepts of nutrigenomics and nutrigenetics, 92.3% did not incorporate genetic testing into their practice; the main barriers of their use were misinformation, limited access to reliable resources, and ethical concerns surrounding genetic testing. Although 86.2% expressed interest in learning about nutrigenetics, only 31.5% were willing to invest in further training. Social media and non-academic sources were important sources of information, raising concerns about their inaccurate content and highlighting their importance in completing the curricula. Patients' demand for genetic testing is limited and directed by disease prevention interests.

CONCLUSIONS

Nutrigenetics is currently an area with limited practical application among Mexican dietitians; however, it is perceived as a valuable tool for future daily practice. The gap between perception and application underscores the need to integrate nutrigenetics into undergraduate curricula and to provide accessible, evidence-based professional development; these are essential to promote the ethical and effective use of nutrigenetics and support the transition toward personalized nutrition.
