Oral administration of lysophosphatidic acid (LPA), a critical intercellular lipid mediator, exerts wound healing and antiulcer effects on gastrointestinal system. To evaluate effects of food‐derived LPA on body homeostasis, we measured LPA levels by liquid chromatography–tandem mass spectrometry in chows, feces, plasma, liver, and visceral fat of mice fed a normal or high‐fat chow supplemented with or without LPA‐rich soybean phospholipids for 30 days. Reductions in daily body weight gains and visceral fat mass were mainly related to lower chow intake by mice fed the LPA‐rich high‐fat chow, whereas reduced body weight gains and fat mass were mainly related to decreased intestinal triacylglycerol absorption in mice fed LPA‐rich chow. Our results showed no significant increase in plasma, liver, or adipose LPA levels, even if a quite high LPA concentration (2.0%) in chows was ingested daily, suggesting limited effects of food‐derived LPA on the lumen side of the digestive tract. © 2018 BioFactors, 44(6):548–557, 2018
