【摘要】：目的研究血清反式脂肪酸(TFA)及过氧化指标与膳食摄入的关系,为大学生合理膳食提供依据。方法招募18~25岁的健康大学生172名。采用食物频率法调查过去3个月内水果、蔬菜、乳类、肉类食物及其制品,以及鱼虾贝类、速食、甜品和油炸食品的摄入频率以及平均每次摄入量,并静脉抽取空腹血5 mL测定血清TFA、丙二醛(MDA)和超氧化物歧化酶(SOD)。结果男生中有19.4%每周摄入油炸食品大于300 g,女生此比例为9.1%;回族学生每周摄入油炸食品大于300 g的比例为18.9%,汉族学生为8.7%。男女学生血清TFA和回汉族血清TFA,MDA水平差异均有统计学意义(t值分别为-2.81,-3.12,-2.81,P值均0.01)。多元回归分析结果显示,血清TFA水平主要与油炸食品、速食、甜品以及乳类及其制品摄入有关,血清MDA水平与油炸食品、蔬菜及制品的摄入有关。结论为防止TFA和丙烯酰胺可能引起的健康危害,应减少油炸食品、速食和甜品、奶茶和奶油等乳制品的摄入,多食用蔬菜及其制品。
[Abstract]:Objective to study the relationship between serum trans fatty acid (TFA), peroxidation index and dietary intake in order to provide basis for reasonable diet of college students. Methods 172 healthy college students aged 18 ~ 25 years were recruited. The frequency of intake and average intake of fruits, vegetables, milk, meat foods and their products, as well as fish and shrimp shellfish, instant food, desserts and fried foods over the past three months were investigated by using the food frequency method. Determination of serum TFA, malondialdehyde (MDA) (MDA) and superoxide dismutase (SOD).) by venous sampling of 5 mL fasting blood Results 19.4% of the boys consumed more than 300 g of fried food per week, the proportion of female students was 9.1%, the proportion of students of Hui nationality more than 300 g of fried food per week was 18.9g, and the proportion of students of Han nationality was 8.7%. There were significant differences in the levels of serum TFA between male and female students and those of Hui Han nationality (t = -2.81). The results of multiple regression analysis showed that the serum TFA level was mainly related to the intake of fried food, instant food, desserts, milk and its products, while the serum MDA level was related to the intake of fried food, vegetables and products. Conclusion in order to prevent the possible health hazards caused by TFA and acrylamide, we should reduce the intake of fried foods, instant foods and desserts, milk tea and cream, and eat more vegetables and their products.
