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.

In plain English

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.

Why this might work

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.

  1. Study: 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.
