The role of a specific omega-3 transporter protein, Mfsd2a, has come under the limelight, thanks to continuous research efforts. The protein has been found instrumental in preventing the liver from storing an excess of fat, sparking hopes for the development of dietary supplements to combat non-alcoholic fatty liver disease (NAFLD).
Understanding the risk: The impact of fatty foods
Overconsumption of fatty foods can trigger a host of health conditions such as cardiovascular disease, obesity, diabetes, and particularly NAFLD. With fat accumulation in the liver, NAFLD can lead to liver inflammation, progressive deterioration, and scarring – commonly known as cirrhosis. The global prevalence of NAFLD is alarming, with around 27% of adults affected. In Singapore, the percentage is even higher at approximately 40%.
Omega-3 fatty liver defense: The findings
Phospholipids, a type of fat, play a crucial role in constructing cell membranes, offering protection to the liver against dietary fat’s adverse effects. The focus of the study revolved around Mfsd2a, which is responsible for transporting a particular phospholipid, lysophosphatidyl choline (LPC), into cells.
The phospholipid protection: The findings
The researchers embarked on rigorous studies using preclinical and human liver samples. They manipulated the activity of Mfsd2a and its lipid uptake to examine the effects. The results indicated that LPC lipids, especially those containing omega-3 fatty acid DHA, could potentially be used for NAFLD prevention in the long run. Dietary supplementation of LPC might protect the liver from the damage induced by a high-fat diet.
Omega-3 Liver health: Looking forward
The team emphasized that the liver has a significant demand for phospholipids, which increases when faced with fatty foods. As NAFLD can take years to develop and escalate to non-alcoholic steatohepatitis and cirrhosis, long-term supplements could offer protection.
The researchers now aim to conduct clinical studies to evaluate LPC supplementation’s effectiveness in NAFLD patients. If successful, this development could be a game-changer for countless individuals globally, affected by this condition. Further investigations into the molecular mechanisms through which LPCs promote liver health are also planned.
