Effects of vegetable consumption on postprandial glucose and lipid metabolism including serum adipocytokine

健康受试者和肥胖和高甘油三酯血症受试者食用了三种测试餐：面包(B)餐、面包黄油(BB)餐、面包黄油菠菜(BBS)餐。分别于空腹、餐后30、60、120、180、240分钟采血。结果：健康受试者BB餐后血糖水平明显低于B餐后，甘油三酯水平显著高于B餐后。BBS餐后30min血糖水平低于B餐后(p&lt；0.05)。肥胖和高甘油三酯血症患者BB餐后甘油三酯水平高于B餐后，BBS餐后30min血糖水平低于B餐和BB餐后。BBS餐后血浆同型半胱氨酸浓度低于BB餐后。BB餐和BBS餐的餐后肝素前脂蛋白脂肪酶质量没有差异。肿瘤坏死因子-α浓度有降低…的趋势BB餐后Se增加，30分钟后下降，BBS餐后回升至空腹水平。从这些结果来看，黄油和面包一起食用可能有助于抑制餐后高血糖，但会导致高甘油三酯血症。在健康受试者中，食用菠菜搭配面包和黄油可能有预防餐后高血糖的可能性。研究2在贸易公司员工中招募受试者，这些受试者被要求接受关于代谢综合征的营养教育。受试者被分配到对照组和VEG组，前者接受常规教育，后者被强调要比平时建议的更多地食用蔬菜。分别于基线和干预后3个月采血。结果：VEG组体重下降3.6 kg，对照组体重下降1.1 kg，差异有统计学意义(p&lt；0.05)。VEG组的蔬菜摄入量增加了约50g，而对照组减少了约150g。强调增加蔬菜摄入量的营养教育对减轻体重是有效的。较少

Healthy subjects and subjects with obese and hypertriglyceridemia consumed three test meals ; bread (B) meal, bread and butter (BB) meal, bread and butter with spinach(BBS) meal. Blood were collected at fasting, 30, 60, 120, 180 and 240 minutes after each test meal consumption.Results : In the healthy subjects, postprandial glucose levels tended to be lower and triglyceride levels were significantly higher after BB meal compared to after B meal. Plasma glucose level at 30 minutes after BBS meal was lower than that of after B meal (p<0.05). In the subjects with obese and hypertriglyceridemia, postprandial triglyceride levels were higher after BB meal compared to after B meal, and plasma glucose level at 30 minutes after BBS meal was lower than that of after B and BB meal. Plasma homocystein concentration was lower after BBS meal compared to after BB meal. Postprandial pre-heparin lipoprotein lipase mass did not differ between the BB and BBS meal. TNF-alpha concentration tended to decrea … More se after BB meal, however, those tended to decrease at 30 minutes and increased to the fasting level after BBS meal. From these results, butter consumption with bread might contribute to suppress postprandial hyperglycemia, but cause hypertriglyceridemia. In the healthy subjects, spinach consumption with bread and butter suggested to have possibility to protect postprandial hyperglycemia.Study 2.Subjects were recruited among trading company employee who were indicated to get nutrition education concerning metabolic syndrome. The subjects were allocated to Control group who were educated as usual, and to Veg group who were emphasized to encourage consuming more vegetables compared to usual advice. Blood was obtained at baseline and 3 month after intervention. Result : Significant change in body weight was observed in the Veg group with 3.6kg decrease more than 1.1kg in the Control group (p<0.05). Vegetable intake increased about 50 g in the Veg group and decreased about 150g in the Control group. Nutrition education emphasized to increase vegetable intake are suggested to be effective for body weight reduction. Less
