Aim: Little research has been conducted on the effect of fatty meal ingestion on heart rate variability (HRV) parameters. The present study aimed to assess the effect of saturated fatty meal on HRV time and frequency domain parameters in overweight and obese late adolescent females. Also to assess the possible correlation between HRV parameters and obesity indices in that particular age group. ...

The flux of glucose carbon to total body fatty acids was measured in unanesthetized mice either after fasting or 50-80 min after they nibbled a small test meal containing 120 mg of glucose (fasted-refed). Flux was calculated from plasma [(14)C]glucose specific activity curves and from total body (14)C-labeled fatty acid 30 min after intravenous injection of tracer [(14)C]glucose. Mobilization o...

BACKGROUND/AIMS Postprandial symptoms of fullness and abdominal discomfort are common after fatty meals. Gastric lipases hydrolyze 10% to 20% of dietary triglycerides during the stomach trituration period of digestion. The aim of this study was to evaluate the effects of acid-resistant lipase on upper gastrointestinal symptoms, including fullness and bloating, as well as on gastric myoelectrica...

Circulating triacylglycerol (TG) arises mainly from dietary fat. However, little is known about the entry of dietary fat into the major TG pool, very low-density lipoprotein (VLDL) TG. We used a novel method to study the specific incorporation of dietary fatty acids into postprandial VLDL TG in humans. Eight healthy volunteers (age 25.4 +/- 2.2 years, body mass index 22.1 +/- 2.3 kg/m2) were fe...

1. An experiment was done with rats (body-weight 160 g) to study the effects on fat metabolism and body composition of low (10 g/kg)- or high (140 g/kg)- fat diets fed as one meal for one 4 h period/d (meal-feeders) or as six spaced meals/d (nibblers). The daily energy intake/unit metabolic body-weight (body-weight 0.73) was the same for all four groups, and this level of intake was about 80% o...

The objectives of this study were to determine the effects of feeding rapeseed (27%, DM basis) and sunflower biodiesel by-products as protein supplements on fatty acid composition (FA), profile (ratios and indices),enzyme activitiesfrom thecarcassin lambs fed cereal-based diets. Simultaneously, itwas examined the relationship between ingested FA and carcass FA. Samples were obtaine dfrommal efa...

Most postprandial studies have investigated the response of a single meal, yet the ingestion of sequential meals is more typical in a Western society. The aim of this review is to explain how natural and stable isotope tracers of fatty acids have been used to investigate the metabolism of dietary fat after single and multiple meals, with a focus on in vivo measurements of adipose tissue metabol...

The mechanism(s) by which sex specific differences in regional body fat distribution develop are not known. We assessed the effects of a high-fat (HF) meal on fatty acid oxidation and uptake into regional fat depots using isotopic tracers and adipose biopsies. Thirty men (BMI 23.6 +/- 0.3 kg/m(2)) and 29 women (BMI 22.4 +/- 0.3 kg/m(2)) received a meal containing [(3)H]triolein. Twelve of the m...

The study was designed to test the effects of dietary supplementation with fish meal or specific n-3 fatty acids on ovarian activity and uterine responses in early lactating cows. From 5 to 50 d in milk (DIM), cows were fed diets that were isonitrogenous, isoenergetic, and isolipidic containing none (control), 1.25, 2.5, or 5% menhaden fish meal (FM) or 2.3% Ca salts of fish oil fatty acids (Ca...

BACKGROUND AND AIMS Sincalide, in conjunction with cholescintigraphy, is necessary for the diagnosis of chronic acalculous cholecystitis. However sincalide is not widely available. This study investigates the use of a commercially available formula as an inexpensive alternative to sincalide, containing a sufficient and known amount of fat to cause gallbladder contraction, and to determine norma...
