RESUMO
Objective:To evaluate the effect of different dietary pattern and soybean oligosac-charides supplementation on the amount and proportion of short-chain fatty acids (SCFA). Method: Twelve healthy students aged 20 to 25 years old were selected in the medical college. The study included 3 periods. In every period the students accepted different dietary patterns in 1st week [1. low animal food diet (LAFD),2. balanced food diet (BD), 3. high animal food diet (HAFD)]. Soybean oligosaccharides (5g/d) were added to different diets in 2nd week. The diet in 1st week was recovered in 3rd week. The study lasted for 9 w. Feces were collected once a week and SCFA was measured by capillary gas chromatography. Results: The total SCFA in feces were increased after taking LAFD, more prominent in acetic acid and butyric acid (P
