摘要目的 探讨奶素食膳食方式与血脂谱的关系.方法 选取268名健康的普食者和388名健康的奶素食者进行横断面研究.采集受试者的基本情况,并肘静脉采血测定空腹血糖(FBG)、总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、载脂蛋白AI(Apo-AI)和载脂蛋白B(Apo-B),以及肝肾功等生化指标.结果 奶素食组TC[(4.15±0.70对4.90+0.92)mmol/L.P<0.01]、HDL-C[(1.17+0.25对1.29+0.23)mmol/L,P<0.01]、LDL-C[(2.43+0.63对3.04+0.82)mmol/L,P<0.01]、Apo-A I[(1.06+0.11对1.22+0.14)g/L,P<0.01]、Apo-B[(0.71±0.17对0.84+0.20)g/L,P<0.01]水平均低于普食组,TC与HDL-C的比值(3.67+0.97对3.89+0.94,P=0.019)也低于普食组.Apo-A I与Apo-B的比值两组间差异无统计学意义.结论 奶素食者具有相对良好的血脂谱特征,奶素食膳食对血脂代谢似具有积极的影响.

abstractsObjective To study the relationship between lacto-vegetarian diet and blood lipid profile. Methods Totally 268 healthy omnivores and 388 healthy lacto-vegetarians were enrolled. The general information, smoking and drinking history, life style, and blood pressure of subjects were obtained from medical examination. Serum lipids, including total cholesterol ( TC), triglyceride ( TG), high-density lipoprotein cholesterol (HDL-C) , apo-lipoprotein A I (ApoA I ) , and apo-lipoprotein B (ApoB) , liver function, and renal function were assayed. Results Lacto-vegetarians had statistical significant lower levels of TC [ (4. 15±0. 70 vs 4.90±0.92) mmol/L,P<0.01 ], HDL-C[ (1.17±0.25 vs 1.29±0.23) mmol/L,P<0.01 ], LDL-C[ (2.43±0. 63 vs 3.04±0.82)mmol/L,P<0.01], Apo-A I [(1.06±0. 11 vs 1. 22±0.14)g/L,P<0. 01 ] and Apo-B[(0.71± 0.17 vs 0. 84±0. 20)g/L,P<0. 01 ], and also lower TC/HDL-C than omnivores. The Apo-A I/Apo-B ratio between two groups showed no difference statistically. Conclusions Chinese lacto-vegetarian diet consumed by healthy monks seems to be significantly associated with better lipid profiles.
