In pig milk-making cells, oleic acid turns on certain fat-handling proteins and helps make more milk fat, and this happens mostly through two specific cell receptors called GPR40 and GPR120.
Scientific Claim
In porcine mammary epithelial cells, oleic acid is associated with increased expression of CD36, FATP4, and FABP3 and enhanced triglyceride synthesis through activation of GPR40 and GPR120 receptors.
Original Statement
“In pMECs, oleic acid upregulated CD36, FATP4, and FABP3 expression and boosted triglyceride synthesis via activation of both GPR40 and GPR120.”
Evidence Quality Assessment
Claim Status
overstated
Study Design Support
Design cannot support claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The abstract claims oleic acid 'boosted' and 'via activation', implying direct causation, but without details on controls, replicates, or statistical validation in cells, only association can be conservatively stated.

Oleic acid-enriched diet improves maternal lactation performance and neonatal growth through GPR40 and GPR120 signaling pathways
The study found that oleic acid, a fat found in milk, helps piglets grow better by turning on specific receptors in the mother’s mammary cells that make more fat for milk — exactly what the claim says.
