Association between serum trans fatty acid and superoxide dismutase with dietary intake among college students

Objective To study association between serum trans fatty acid(TFA) and superoxide dismutase(SOD) with dietary intake among college students,and to provide a basis for college students' rational dietary.Methods A total of 172 volunteers aged 18-25 were recruited.Food frequency questionnaire was used to investigate the frequency and the average intake of fruits,vegetables,milk class,meat and aquatic product,fast food,dessert,fried food in the past three months.Serum TFA,MDA and SOD were determined by extraction of venous blood on an empty stomach.Results More than 300 g fired food was consumed in male(19.4%),female(9.1%),Hui(18.9%) and Han(8.7%) students each week.The differences of serum TFA between male and female,as well as TFA and MDA between Hui and Han students were statistically significant(t =-2.81,-3.12,-2.81,P<0.01).According to the multiple regression analysis,serum TFA was related to consumption of fried and fast food,dessert and dairy products,and serum MDA was related to the intake of fried food and vegetables.Conclusion In order to decrease the health hazard of TFA and acrylamide,people should reduce the intake of fried and fast food,dessert and milky tea or cream,and eat more vegetables and its products.
