Abstract
Improve lipid metabolism and absorption of calcium and magnesium in cholesterol-fed rat were studied. To accomplish this aim potato peel and wheat bran breads were investigated. Thus 4 groups of 8 rats each were used. The first group was fed on basal diet (control). The other groups fed on basal diet +1 % cholesterol. Potato peel bread (PP-bread) ( 10 % of diet ) was added in 3rd group, while wheat bran bread (WB-bread) ( 10 % of diet ) was used in 4th group. An increase of short chain fatty acids (SCFA) was observed in content in the feces of rats that consumed either of the two different kind of bread. Potato peel bread diet increased the acetate, propionate and butyrate concentrations compared to wheat fiber group. Consequently, both absolute apparent Ca absorptions (mg/d) and relative (%)were affected by both treatments, and those were greater (51 ± 2.4 and 71.5 ±1.68 ) by PP-bread diet than that of WB-bread diet ( 45 ±2.1 and 62 ±3.8 ). Relative apparent Mg absorptions were higher after ingestion of PP-bread diet as compared to those that fed on WB-bread diet. The plasma lipoprotein shows a reduction of LDL (-66.6% and -61.1) in rats fed on PP-bread and WB-bread diets, respectively compared to hypercholesterolemic group. The presence of potato and wheat fiber in the diet increased HDL level (10.8 % and 7.8 %, respectively) compared to hypercholesterolemic group. Triglyceride and LDL concentrations were significantly lower in rats fed with potato fiber-enriched diet as compared to those that fed on wheat fiber diet (68.4 ± 4.51 % vs. 74.4 ± 6.41 % and 36.7 % ±4.52 vs. 42.8 % ±10.36, respectively ).
