Current evidence and future perspectives on n-3 PUFAs

Area of Science:

• Biochemistry
• Human Nutrition
• Preventive Medicine

Background:

• n-3 polyunsaturated fatty acids (PUFAs) are essential for mammalian health and involved in numerous physiological processes.
• Deficiency in n-3 PUFAs is linked to various diseases, highlighting their importance in metabolism and overall well-being.
• Current recommendations often suggest general increases in n-3 PUFA intake, including specific dosages for cardiovascular health.

Purpose of the Study:

• To advocate for a shift from generic n-3 PUFA intake advice to a personalized, evidence-based approach.
• To emphasize the need for tailored n-3 PUFA consumption strategies in the era of personalized medicine.
• To highlight the 'pleiotropic effects' and individual factors influencing n-3 PUFA efficacy.

Main Methods:

• Review of existing literature on n-3 PUFA physiological actions and health impacts.
• Analysis of current global recommendations for n-3 PUFA intake.
• Discussion of factors relevant to personalized n-3 PUFA supplementation.

Main Results:

• n-3 PUFAs exert broad physiological effects beyond cardiovascular health, influencing maternal and offspring health, immunity, cognition, and more.
• The efficacy of n-3 PUFAs is dose-dependent and patient-specific.
• Generic advice for increasing n-3 PUFA intake needs refinement.

Conclusions:

• A personalized medicine approach is necessary for n-3 PUFA supplementation.
• Individualized assessment considering 'pleiotropic effects', dosage, genetics, diet, and cost-benefit is crucial.
• Tailored n-3 PUFA indications will optimize health outcomes and resource utilization.
