The Role of Meat Lipids in Nutrition and Health: Balancing Benefits and Risks.

Abstract

Meat lipids are determinants of the nutritional, sensory and physiological qualities of meat, encompassing triglycerides, phospholipids, cholesterol and bioactive compounds. These lipids provide essential fatty acids, including omega-3 and omega-6 polyunsaturated fatty acids, critical for metabolic regulation, inflammation control and cognitive health. However, the dual role of meat lipids as essential nutrients and potential contributors to health risks, such as cardiovascular disease and oxidative stress, necessitates a nuanced understanding. This review evaluates meat lipids' biochemical diversity, nutritional contributions and health implications, balancing their benefits and risks. It examines factors influencing lipid composition, including species, diet and processing methods, emphasising strategies such as omega-3 enrichment and antioxidant supplementation to enhance lipid quality. Advances in functional meat products, such as hybrid formulations combining plant and animal lipids, are highlighted for their potential to improve health outcomes. Emerging technologies in lipidomics provide deeper insights into lipid oxidation pathways and nutritional profiling, aiding in the development of safer, higher-quality meat products. By synthesising recent evidence, this review offers insights into dietary guidelines, optimises consumer choices and informs sustainable meat production practices aligned with public health and environmental goals.
