Summary
This narrative review examines the lipo-nutritional quality of pork by synthesising research on lipid deposition mechanisms and fatty acid composition regulation. The authors discuss how pork's nutritional value—particularly its PUFA content including n-3 PUFA—relates to human health outcomes such as cardiovascular protection and energy metabolism. The review evaluates multiple regulatory strategies, including emerging approaches such as faecal transplantation, molecular design breeding, and non-coding RNA manipulation, as means to improve pork's fatty acid profile and overall nutritional quality.
Regional applicability
The review's focus on genetic selection, nutrition-based interventions, and emerging molecular technologies is applicable to UK pig production systems seeking to enhance meat nutritional quality. However, the geographic origin of primary studies cited is unclear, and UK-specific data on feasibility and cost-effectiveness of these approaches would be needed to guide industry adoption.
Key measures
Fatty acid composition (SFA, MUFA, PUFA profiles); intramuscular fat (IMF) content; triglyceride and phospholipid levels; n-3 PUFA concentration
Outcomes reported
The review synthesises current research on lipid deposition mechanisms and fatty acid composition in pork, examining how breeding, environmental control, nutritional regulation, faecal transplantation, molecular design breeding, and non-coding RNA influence lipid profiles.
