Ethical challenges in nutrigenomics research and personalized nutrition arise from international studies and biobanks. Personalized nutrition advice based on genotype requires more scientific evidence before widespread use.

Area of Science:

  • Genetics and Nutrition
  • Bioethics
  • Public Health

Background:

  • Nutrigenomics research explores gene-diet interactions for common diseases.
  • International research collaborations and biobanks are rapidly expanding.
  • Ethical principles like autonomy and justice face new challenges.

Purpose of the Study:

  • To provide an overview of ethical issues in nutrigenomics research.
  • To highlight ethical considerations in international collaborative projects.
  • To discuss the ethical implications of personalized nutrition.

Main Methods:

  • Literature review and ethical analysis.
  • Examination of research ethics principles (autonomy, beneficence, nonmalfeasance, justice).
  • Discussion of challenges posed by cross-border research and biobanks.

Main Results:

  • International research presents unique ethical challenges, some unresolved.
  • The scientific basis for genotype-based personalized nutrition advice is currently limited.
  • Nutrigenomics offers potential public health benefits through understanding diet-gene mechanisms.

Conclusions:

  • Researchers must be aware of ethical issues in international nutrigenomics projects.
  • Personalized nutrition recommendations require stronger scientific validation.
  • Nutrigenomics holds promise for improving public health and disease prevention.
