Comparative effects of low‐carbohydrate, full‐strength and low‐alcohol beer on gastric emptying, alcohol absorption, glycaemia and insulinaemia in health

摘要

Aims The aim of this study was to evaluate the comparative effects of low‐carbohydrate (LC), full‐strength (FS), and low‐alcohol (LA) beer on gastric emptying (GE), ethanol absorption, glycaemia and insulinaemia in health. Methods Eight subjects (four male, four female; age: 20.4?±?0.4?years; BMI 22.7?±?0.4?kg/m2) had concurrent measurements of GE, plasma ethanol, blood glucose and plasma insulin for 180?min on three separate occasions after ingesting 600?mL of (i) FS beer (5.0%?w/v, 246?kcal, 19.2?g carbohydrate), (ii) LC beer (4.6%?w/v, 180?kcal, 5.4?g carbohydrate) and (iii) LA beer (2.6%?w/v, 162?kcal, 17.4?g carbohydrate) labelled with 20?MBq 99mTc‐calcium phytate, in random order. Results There was no difference in the gastric 50% emptying time (T50) (FS: 89.0?±?13.5?min vs LC: 79.5?±?12.9?min vs LA: 74.6?±?12.4?min; P?=?.39). Plasma ethanol was less after LA than LC (P?
