摘要：
The present study was conducted to compare the effect of soy polysaccharide (Fibrem) and sugar-beet (Fibrex) on zinc and folic acid absorption when incorporated into enteral formulae. Following an overnight fast, 15 adults were challenged with an oral dose of zinc (60 mg) and folic acid (600-mu-g) given with enteral formula without fibre, or with 15 g of dietary fibre from Fibrem or Fibrex. Serum concentrations of zinc and folic acid were measured at zero-time and at hourly intervals for up to 5 h. Results showed that Fibrem caused a significant decrease in the concentrations of zinc and folic acid. However, Fibrex caused a slight increase in serum zinc concentration and a less pronounced decrease in serum folic acid concentration as compared to Fibrem. We conclude that for patients who are at risk of zinc or folic acid deficiency, the fibre source in enteral formulae should be selected carefully.
