目的:探讨柑橘类果汁的饮用对改善青年人群血脂的作用,为促进青年人群的健康、预防慢性疾病提供一定的依据。方法:以上海体育学院36名有轻度血脂偏高或超重的在校学生作为实验对象,年龄在18~33岁之间。对所有实验对象进行体质测量,并测血脂(HITACHI7600),包括TC、TG、LDL-C、HDL-C4项。之后随机分为饮食调节+果汁干预组(F+J)、饮食调节组(F)、果汁干预组(J)和对照组(C),每组9名实验对象,对F+J组和F组进行2周饮食调节后,分别进行3周的饮食调节或柑橘类果汁干预,果汁干预采用双盲法,之后测量血脂,并于3周后回访测血脂。研究结果:(1)5周饮食调节和3周的柑橘类果汁干预后,F+J组、F组和J组血脂均得到明显的改善,而对照组无显著性差异。(2)F+J组与F和J组相比,血脂改善的效果更为明显,其TC和LDL-C的下降值都明显高于F组和J组。(3)3周后回访,除C组外,血脂状况都出现一定的反弹,其中F+J组的TC、LDL-C明显上升,J组的LDL-C明显上升,F组的TC、LDL-C明显上升,对照组C无显著性差异。结论:(1)柑橘类果汁可在不改变生活习惯的情况下,显著改善青年的血脂水平。(2)柑橘类果汁干预和饮食调节相结合,对青年人的血脂水平改善效果更为显著。
Objective: To explore the effect of drinking citrus juice on improving blood lipid in young people, and to provide some evidences for promoting the health of young people and preventing chronic diseases. Methods: Thirty-six in-school students with mild hyperlipidemia or overweight in Shanghai Institute of Physical Education as experimental subjects, aged 18-33 years old. All subjects were subjected to physical measurement and blood lipid (HITACHI 7600), including TC, TG, LDL-C and HDL-C4. (F + J), dietary adjustment group (F), fruit juice intervention group (J) and control group (C). Nine subjects in each group were divided into two groups: F + J group and F group After two weeks’ diet adjustment, the rats in each group were given dietary adjustment or citrus juice intervention for 3 weeks respectively. The double-blind method was used to measure the fruit juice, then the blood lipid was measured and returned to the blood test 3 weeks later. Results: (1) After 5 weeks of dietary regulation and 3 weeks of citrus juice intervention, the blood lipid levels of F + J group, F group and J group were significantly improved, while there was no significant difference in the control group. (2) Compared with F and J group, F + J group showed more obvious improvement of blood lipids, and the decreased values of TC and LDL-C were significantly higher than F and J group. (3) After 3 weeks of follow-up, there was a certain rebound in blood lipid status except for group C, in which TC and LDL-C of F + J group were significantly increased, LDL-C of J group was significantly increased, TC and LDL C was significantly increased, the control group C no significant difference. Conclusions: (1) Citrus juice can significantly improve the level of blood lipid in young people without changing the living habits. (2) The combination of citrus juice intervention and diet regulation has a more significant effect on improving the blood lipid level of young people.
