Ethical issues raised by personalized nutrition based on genetic information

Area of Science:

• Bioethics
• Nutritional Science
• Personalized Medicine

Background:

• Modern society often equates wellbeing with external factors like health, leading to unrealistic expectations.
• Food is recognized as crucial for wellbeing, extending beyond its role in maintaining health.
• Ethical analysis of personalized nutrition is based on principles of autonomy, nonmaleficence, beneficence, and justice.

Purpose of the Study:

• To ethically analyze personalized nutrition, considering genetic testing, counseling, and specialized dietary products.
• To evaluate the current limitations and future recommendations for personalized nutrition strategies.

Main Methods:

• Ethical framework analysis using four core principles.
• Review of current personalized nutrition approaches, including genetic testing and product development.
• Assessment of the predictive value and limitations of genetic testing in nutrition.

Main Results:

• The predictive value of genetic tests for personal nutrition is currently limited and largely experimental.
• A tendency exists to overemphasize health and external circumstances in defining wellbeing.
• Personalized nutrition approaches, while potentially beneficial, carry risks such as the medicalization of diet.

Conclusions:

• Personalized nutrition must be grounded in robust scientific evidence and phenotypic analysis where appropriate.
• Genetic testing should be employed only when a clear advantage is demonstrated, with expert counseling.
• Direct-to-consumer marketing of genetic tests for nutrition should be discouraged to ensure responsible application.
