n-3 PUFA and obesity: from peripheral tissues to the central nervous system

Area of Science:

• Nutrition Science
• Biomedical Research
• Inflammation Studies

Background:

• Obesity rates are rising, necessitating novel therapeutic strategies beyond current prevention and treatment methods.
• Obesity causes systemic damage and is a significant risk factor for chronic diseases, including brain damage.
• Obesity is associated with a chronic inflammatory state, suggesting inflammation modulation as a therapeutic target.

Purpose of the Study:

• To review the existing literature on the use of n-3 PUFA in the treatment of obesity.
• To explore the potential of n-3 PUFA as an alternative therapeutic approach for obesity management.
• To summarize findings from animal and human studies regarding n-3 PUFA's effects on obesity-related alterations.

Main Methods:

• This narrative review synthesizes information from published animal and human studies.
• The review examines the pathophysiology of obesity, including peripheral and central nervous system effects.
• It details the sources, general effects, and specific applications of n-3 PUFA in obesity treatment.

Main Results:

• n-3 PUFA, particularly EPA and DHA from fish oil, possess anti-inflammatory properties.
• These fatty acids offer benefits such as reduced triglycerides, improved cardiac function, and lower blood pressure.
• Studies indicate n-3 PUFA's potential to mitigate obesity-induced damage in both peripheral tissues and the brain.

Conclusions:

• n-3 PUFA represent a promising therapeutic avenue for obesity treatment due to their anti-inflammatory and beneficial physiological effects.
• Further research into n-3 PUFA supplementation could lead to effective strategies for managing obesity and its associated health complications.
• Understanding the impact of n-3 PUFA on both peripheral and central nervous system alterations in obesity is crucial for comprehensive treatment approaches.
