Researchers used newborn pigs to study how fat type in infant formula affects the developing liver. They fed two simplified formulas that differed only in fat type: one rich in medium-chain fats from coconut oil and the other rich in long-chain fats from animal fat that is more like whole sow milk. Both groups had the same calories and protein.
Pigs given the medium-chain formula accumulated liver fat faster, and fat was visible within seven days. The team found that young livers can build up fat even when fat-burning processes increase. The researchers stressed that parents should not avoid formula; breast milk is the gold standard, but formula is a needed alternative when breastfeeding is not possible.
