Compare levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL) and high density lipoprotein (HDL) among vegetarians and omnivores.
Blood samples were collected from 76 individuals--both males and females--separated in four different diet groups: omnivores, lacto-ovo vegetarians, lacto vegetarians, and restricted vegetarians (or vegans). Dosing was done for: TC, LDL, HDL and TG.
Significant difference was reported for TC, LDL and TG levels among the samples. Higher levels were reported by omnivores, with decreased levels for vegetarians as animal products were restricted, with lowest levels having been reported by vegans. Mean and standard deviation for TC were 208.09 +/- 49.09 mg/dl in the group of omnivores, and 141.06 +/- 30.56 mg/dl in the group of vegans (p < 0.001). LDL values for omnivores and vegans were respectively: 123.43 +/- 42.67 mg/dl and 69.28 +/- 29.53 mg/dl (p < 0.001). As for TG, those values were 155.68 +/- 119.84 mg/dl and 81.67 +/- 81.90 mg/dl (p < 0.01). As for HDL level no difference was reported between the samples, but HDL/TC ratio was significantly higher in vegans (p = 0.01).
Vegetarian diet was associated to lower levels of TG, TC and LDL as compared to the diet of omnivores.
比较素食者和杂食者的甘油三酯（TG）、总胆固醇（TC）、低密度脂蛋白（LDL）和高密度脂蛋白（HDL）水平。
从76名男性和女性个体中采集血样，将其分为四个不同的饮食组：杂食者、蛋奶素食者、乳素食者和严格素食者（或纯素食者）。检测项目包括：TC、LDL、HDL和TG。
样本中TC、LDL和TG水平存在显著差异。杂食者的这些水平较高，随着动物产品摄入量的减少，素食者的水平降低，纯素食者的水平最低。杂食组TC的均值和标准差分别为208.09±49.09mg/dl，纯素食组为141.06±30.56mg/dl（p<0.001）。杂食者和纯素食者的LDL值分别为：123.43±42.67mg/dl和69.28±29.53mg/dl（p<0.001）。至于TG，这些值分别为155.68±119.84mg/dl和81.67±81.90mg/dl（p<0.01）。至于HDL水平，样本之间未报告差异，但纯素食者的HDL/TC比值显著更高（p=0.01）。
与杂食者的饮食相比，素食与较低的TG、TC和LDL水平相关。
