简要总结
The objective of the study is to identify biomarkers for acute intake of beer and alcohol in individuals with a high or low habitual intake. Furthermore, we wish to identify compounds and metabolites in different types of beer and alcohol, which can serve as compliance markers for intake under the test conditions (blood tests and urine samples). We also wish to determine the acute effects of these beverages on plasma glucose and insulin response, compared to regular soda.
详细描述
The study is designed as a randomized, 4-way single-blinded cross-over intervention study. The participants are randomized individually to the order by which they shall receive 4 test meals. There will be implemented a standardized lunch which includes respectively 1) Light/alcohol-free (Tuborg Super Light 0,1% alcohol), 2) Regular lager (4,6% alcohol), 3) Strong beer(7,2% alcohol) and 4) a control drink without alcohol but with the same energy content (carbohydrate and protein) as the average of the other beverages ("sportsdrink"). Besides 330 ml of each test drink, each test meal consists of grilled cheese sandwiches (Tulip Food Company) and the amount of toast adjusted according to the type of drink served with each meal, so the content of macronutrients is the same in each meal.
The study includes 16-20 participants, randomized as to which order they will receive the 4 test meals with a washout period of at least 6 days in between test days. Upon arrival the test persons are asked to urinate (baseline sample), and at the 1st visit they are then weighed, height is measured and body composition (bioimpedance) is measured. After resting briefly, a baseline blood sample is taken and blood pressure is measured (1st and 4th visit). 45 minutes after start of the test meal the first postprandial blood sample is taken, and again after 45, 120 and 180 minutes. Urine is collected again at 0-90 min, 90-180 min and 3-24 hours after the test meal. Participants are provided with containers and equipment for this purpose, and must submit samples on an ongoing basis to the Dept. of Nutrition, Exercise and Sports.

结局指标
主要结局
Area under the curve (AUC) for glucose
时间窗: 0-180 minutes
Glucose is measured at 0, 45, 90, 120, and 180 min after the test meal and the area is determined by the trapezoid method.
次要结局
- Area under the curve for insulin(0-180 min)
- Plasma concentration of fatty acid ethyl esters (FAEE)(Change from 0-180min)
- Blood level of ethanol(180 min)
- Plasma beer metabolites (metabolic profiling with NMR and mass spectrometry).(After the intervention)
- Urinary content of paraaminobenzoic acid (PABA)(24hour pooled urine from each volunteer)
- Urinary content of ethyl glucuronide (EtG) and ethyl sulphate (EtS)(0-24 hours)
- Blood content of ethyl glucuronide (EtG) and ethyl sulphate (EtS)(0-180 min)
- Urinary content of acetaldehyde (ethanal)(0 -24 hrs)
- Urinary compounds of beer metabolites(0-24 hrs)
- Blood pressure(baseline and at time -30min on the last day of intervention.)
- Body fat mass and body fat percentage(baseline)
- Urinary creatinine(0-24hrs)
