Gender Dependent Difference in Lipemia After 6 x OFTT in Young Healthy Subjects

Hyperlipidemia Clinical Trial

Official title: Gender Dependent Difference in Postprandial Lipemia and Glucose Responses After Six Different Fat Tolerance Tests in Young Healthy Subjects

Status Completed

Clinical Trial Summary

The investigators wanted to study the postprandial lipemia after six oral fat tolerance test with varying amounts of saturated fat in young healthy subjects.

Clinical Trial Description

With six different types of butter added in random order to potatoes the investigators studied postprandial lipemia (PPL), lipoprotein, glucose, and insulin increments for eight hours in 14 young, lean, healthy students, seven of each gender.

The six, isocaloric meals contained 55.1 g carbohydrate, 5.8 g protein, 82.3 g fat, and 4177 kJ. The potatoes, without skin, were boiled in 20 minutes in excess of water with 5 g of salt added, were blended in 4 minutes and served hot. The meals were ingested over 10 minutes, with 250 ml tap water. The following 8 hours the participants stayed at the clinic to watch television, read or take a short walk of 10 minutes.

Blood samples were drawn at -15, 0, 30, 60, 90,120,180,240,300,360, 420 and 480 minutes after the meals and processed after each drawing. After blood collection, plasma was immediately separated by centrifugation at 3000 rpm for 10 minutes at 4°C.

The area under the curve (AUC) were determined for TG, HDL, LDL, total cholesterol, FFA, insulin, and glucose concentrations by the trapezoid method. Multiple regression was performed to adjust for age, gender, meals, and BMI to the variance of postprandial responses. The difference between meals were tested with ANOVA. If p<0.05 in ANOVA, post-hoc-testing with Student-Newman-Keul's test was performed to identify, which meal was significantly different from the other, and to minimize the risk of error by multiple testing. ;
