PURPOSE To investigate whether a single session of intermittent games activity would reduce postprandial lipemia. METHODS Twelve male volunteers completed three 2-d trials: rest, continuous exercise, and intermittent games activity. Trials were performed a minimum of 6 d apart in a balanced crossover design. In the rest trial, subjects took no exercise on day 1. On day 1 of the continuous and...

OBJECTIVES Postprandial lipemia worsens after menopause, but the mechanism remains unknown. The hypothesized menopause-related postprandial lipemia would be (1) associated with reduced storage of dietary fatty acids (FA) as triglyceride (TG) in subcutaneous adipose tissue (SAT) and (2) improved by short-term estradiol (E2 ). METHODS Twenty-three pre- (mean ± SD: 42 ± 4 years) and 22 postmenop...

OBJECTIVE Genetic variants of ABCA1, an ATP-binding cassette (ABC) transporter, have been linked to altered atherosclerosis progression and fasting lipid concentration, mainly high-density lipoproteins and apolipoprotein A1; however, results from different studies have been inconsistent. METHODS AND RESULTS To further characterize the effects of ABCA1 variants in human postprandial lipid meta...

BACKGROUND The triacylglycerol structure of saturated fats may influence postprandial lipemia. OBJECTIVE We tested the hypothesis that high-fat meals rich in palmitic acid (16:0) in the sn-2 position decrease lipemia. DESIGN Postprandial changes in plasma lipids, apolipoprotein B48, and cytokines were compared in healthy men (n = 25) and women (n = 25) by using a randomized crossover design...

This study examined changes in postprandial lipemia in endurance-trained people during a short interruption to training. Nine men and one woman (ages 18-55 yr) undertook fat tolerance tests after 15 h, 60 h, and 6.5 days without exercise. The test meal (1.2 g fat, 1.1 g carbohydrate, 66 kJ/kg body mass) was consumed after a 12-h fast. Postprandial lipemia increased rapidly with detraining (area...

BACKGROUND Plant cell walls are known to influence the rate and extent of lipid release from plant food tissues during digestion; however, the effect of cell wall structure on postprandial lipemia is unknown. OBJECTIVE The objective was to investigate the effects of lipid release (bioaccessibility) on postprandial lipemia by comparing lipid encapsulated by cell walls with lipid present as fre...
