ABSTRACT Their work provides evidence in murine models that the bile acid pool may function as a tunable filter whose selectivity for different fatty acids depends on bile acid concentration and composition. This framework suggests a selective decoupling of the absorption of excessive saturated fatty acids (SFAs) from that of beneficial polyunsaturated fatty acids (PUFAs) in murine models. Importantly, these findings were derived from mice, and their direct applicability to humans is constrained by well‐documented interspecies differences in bile acid composition, a point revisited later in this commentary. This selective mechanism permits the exclusion of metabolically harmful lipids while preserving the uptake of essential nutrients. In this commentary, we examine these findings, contrast them with conventional lipase inhibition strategies, and assess the translational challenges posed by interspecies differences in bile acid profiles.
