Abstract Psyllium seeds (plantago ovata) are a major source of soluble and viscous gel-forming fiber that has been associated with many health benefits. This study was carried out to investigate the chemical, technological and biological effects of psyllium seeds powder (psp) in obese rats fed on a high-fat. It contained 16.00% protein, 4.50% fat, 3.50% ash and 50.50 % total carbohydrate Also, it contained 186, 270, 39.85, 920, 860, 19.5, 8.1 and 4.74 mg/100g for Ca, Mg, Na, K, P, Fe, Zn and Mn, respectively. Total essential amino acids were 48.60% while, total nonessential amino acids were 49.40%. leucine to isoleucine ratio (1.60) was higher than casein (1.04) while, methionine to glycine ratio (0.34) and lysine to arginine ratio (1.18) were lower than casein (1.72 and 1.78, respectively). Computed protein efficiency and biological valuewere 2.50 and 76.14. Meanwhile, psyllium seeds were substituted by 3, 6, 9 and 12% of balady bread to increase its fiber content, 3% and 6% were the best replacement levels, increasing the percent of substituted powder caused a reduction in the organoleptic properties of balady bread. On the other hand , feeding with a high-fat diet caused an increase in the final weight, BWG (%), feed intake, serum glucose, serum lipids, kidney and liver functions as compared negative control group (G1) as result of obesity. feeding with psyllium seeds powder on obese rats fed a high-fat diet significantly reduced in the final weight, BWG, feed intake and FER. Main while, serum glucose was reduced in all treated groups (G3, G4, G5 and G6) as compared with the positive control group. This reduction was ranged from 84.25 mg/dl(G3) to 76.00 mg/dl (G6) furthermore, G6 that fed on 12% psp whose showed the highest decreased on TC,TG and LDL by means 134,98.25,60.35 mg/dl, respectively and highest increased in HDL by mean 55.25 mg /dl as compared with the positive control group (G2) followed by G5. All treated groups referred to improve kidney and liver functions and histopathological changes as compared with the positive control group. In conclusion,present study recommended that the daily consumption of psyllium seed obese patient’s diets could improve serum glucose , lipid profile and promote weight loss.Key words: psyllium seeds, chemical composition, minerals, obesity, fibre, lowering glucose and lipid profile.” |
