New research has proved that certain special fats found in blood are essential for human brain growth and function. The two studies showed that mutations in the protein Mfsd2a causes impaired brain development in humans. Mfsd2a is the transporter in the brain for a special type of fat called lysophosphatidylcholines (LPCs) — composed of essential fatty acids like omega-3. These studies show, for the first time, the crucial role of these fats in human brain growth and function.
