The Claim
Total fatty acid content and accretion of saturated and omega-9 fatty acids in the fetal brain increase in parallel with whole brain weight during the third trimester of gestation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
During the third trimester of pregnancy, the amount of saturated and omega-9 fatty acids in the developing fetal brain increases at the same rate as the overall size of the brain.
See the scientific wording
Total fatty acid content and accretion of saturated and omega-9 fatty acids in the fetal brain parallel increases in whole brain weight during the third trimester, indicating that overall lipid accumulation is tightly coupled to structural brain growth.
As the fetal brain grows rapidly in the last trimester, it takes in basic fats from the mother and turns them into specialized fats that become part of brain cell membranes. These specialized fats build the structure of nerve cells and their connections, allowing the brain to expand in size and complexity at the same time.
What the research says
1 studyStudy: Intrauterine fatty acid accretion rates in human brain: implications for fatty acid requirements.
As a baby's brain grows bigger in the last months before birth, it also gathers more fat — like building a house and filling it with insulation at the same time. This study shows that the fat increases exactly as the brain grows, meaning fat is a key part of how the brain develops.
