The long-term nutritional efficacy of a highly-pure-enriched-cellulose (HPEC) diet and its effects on lipid metabolism and oxidant/antioxidant status were investigated in obese offspring of streptozotocin-induced diabetic rats. Diabetes in pregnant rats was induced by intraperitoneal injection of streptozotocin on day 5 of gestation. Control pregnant rats were injected with citrate buffer. At weaning offspring of diabetic and control rats were fed HPEC or control diet, they were housed individually in metabolic cage for 2 months to investigate the nutritional efficacy of the diets. Consumption of HPEC diet decrease weight gain and energy intake, increase fecal weight and reduce lipid and protein digestibility; however, these diet had no effect on protein utilization, and nitrogen balance remained positive which confirms that HPEC diet had no significant long-term nutritional risks. Indeed for obese offspring from diabetic rats, these diet associated with high satiety promote weight loss, and provide reasonable glycemic control, these diet also lower blood lipids concentration and correct the imbalance of oxidant/antioxidant system. HPEC diet had a protective effect against long-term metabolic abnormalities associated with macrosomia.
在链脲佐菌素诱导的糖尿病大鼠的肥胖后代中,研究了高纯度富集纤维素(HPEC)饮食的长期营养功效及其对脂质代谢和氧化/抗氧化状态的影响。在妊娠第5天通过腹腔注射链脲佐菌素诱导妊娠大鼠患糖尿病。对照妊娠大鼠注射柠檬酸盐缓冲液。在断奶时,将糖尿病大鼠和对照大鼠的后代分别喂食HPEC或对照饮食,将它们单独饲养在代谢笼中2个月,以研究饮食的营养功效。食用HPEC饮食可减少体重增加和能量摄入,增加粪便重量,并降低脂质和蛋白质消化率;然而,这些饮食对蛋白质利用没有影响,氮平衡仍为正值,这证实HPEC饮食没有显著的长期营养风险。事实上,对于糖尿病大鼠的肥胖后代,这些具有高饱腹感的饮食可促进体重减轻,并提供合理的血糖控制,这些饮食还可降低血脂浓度并纠正氧化/抗氧化系统的失衡。HPEC饮食对与巨大儿相关的长期代谢异常具有保护作用。
