Different sources of dietary fibre (cellulose, pectin, Isabgol, cabbage and guava) were fed to weaning rats for 5 weeks to study their effect on serum vitamins. Both the plant foods (cabbage and guava) were analysed for dietary fibre. Guava was found to be a good source of dietary fibre constituting 51.77% of dry pulp, whereas cabbage contained only 16.17%. Cellulose was the major component of dietary fibre in both the plant foods. The concentration of vitamin A and thiamine in the serum of fibre-fed rats was significantly lower than that of rats on a fibre-free diet. However, the amount of vitamin A in serum decreased significantly with the increase in level of dietary fibre, but the decrease was non-significant in the case of thiamine.
将不同来源的膳食纤维（纤维素、果胶、洋车前子壳、卷心菜和番石榴）喂给断奶大鼠5周，以研究它们对血清维生素的影响。对两种植物性食物（卷心菜和番石榴）都进行了膳食纤维分析。发现番石榴是膳食纤维的良好来源，占干果肉的51.77%，而卷心菜仅含16.17%。纤维素是这两种植物性食物中膳食纤维的主要成分。喂食纤维的大鼠血清中维生素A和硫胺素的浓度显著低于无纤维饮食的大鼠。然而，血清中维生素A的含量随膳食纤维水平的增加而显著降低，但硫胺素的情况下降不显著。
