The changes in the postprandial serum NEFA (a) and TAG levels (b) in response to the oral fat-loading test (OFLT) meal. The black circles indicate the level after the intake of the control FM, and the white circles indicate the level after the intake of active FM. The incremental areas under the curves (iAUC) are shown as inserts. Values are expressed as mean (SE). *P < 0.05, **P < 0.01, versus the control FM. Abbreviations: NEFA, non-esterified fatty acid; TAG, triacylglycerol; FM, fermented milk.
