摘要
研究大豆油及其与棕榈油的调和油对健康成人餐后血脂及氧化应激水平变化的影响。选择22名健康成人为研究对象,先以大豆油制成的流质负荷膳干预,随后以大豆油与棕榈油的调和油(0.9∶1)制成的流质负荷膳干预,2次干预间隔4周,开展餐后脂代谢实验,测定和观察餐后不同时间点血清血脂和氧化应激水平指标的含量和变化趋势。结果显示,2组油对餐后血清甘油三酯、高密度脂蛋白、低密度脂蛋白和丙二醛水平变化趋势的影响显著不同;调和油组餐后血清甘油三酯和丙二醛时间曲线下增加的面积大于大豆油组;而大豆油组餐后血清高密度脂蛋白和低密度脂蛋白时间曲线下增加的面积大于调和油;对于餐后血清总胆固醇、载脂蛋白A1和载脂蛋白B水平变化趋势的影响,2组差异则无统计学意义。因此,相比于大豆油,大豆油与棕榈油的调和油对健康成人餐后血脂的影响有利有弊,作为一种新型调和油仍需进一步研究。
To observe and understand the effects of soybean oil and its blend oil with palm oil on postprandial lipid metabolism and oxidative stress level in healthy adults.A postprandial lipid metabolism experiment was conducted on 22 healthy adult subjects with two different lipid - loaded diets,first with a lipid - loaded diet made of soybean oil,followed by soybean oil and its blend oil with palm oil ( 0.9∶ 1),and the washout period of these two interventions was 4 weeks,to determine and observe the content and trend of serum lipid and oxidative stress level at different times after the meal.The results showed that the these two groups of two oils had significantly different effects on the changes of postprandial serum triglyceride,high - density lipoprotein,low - density lipoprotein and malondialdehycle levels;the increased area under the time curve of serum triglyceride and malondialdehycle in the blend oil group was larger than that in the soybean oil group,while the increased area under the time curve of serum low - density lipoprotein and high - density lipoprotein in soybean oil group was larger compared with the blend oil group.There was no significant difference between the two groups in the effects of the change trend of postprandial serum total cholesterol, apolipoprotein A1 and apolipoprotein B levels.Therefore,when compared with soybean oil,the blend oil of soybean oil and palm oil has its pros and cons for healthy human in the effects of postprandial lipid levels it need to be further research as a new type of blend oil.
