以河北医学院回民食堂的35名学生为试验对象,除每天平均由膳食中摄取V_A362Iu外,平均每天吃烹调强化油25g/人,该油加了V_A醋酸酯3000Iu,VE8mg为抗氧化剂。以汉民食堂14名学生为对照组,除每天每人平均由膳食中摄取VA412Iu外,不吃强化VA油。两组都观察40天,在实验开始和终了时,各测暗适应功能。实验组暗适应功能前后对比显著提高(P<0.01);对照组无变化(P>0.05)。我国膳食结构是以植物性食品为主,膳食中供给VA不足,推广强化VA植物油,经济可行。
Taking 35 students of Hui Canteen in Hebei Medical College as test subjects, the average daily intake of dietary V_A362Iu was 25 g cooking oil per day plus V_A acetate 3000 Iu and VE 8 mg as antioxidants. Han students canteen 14 students as a control group, in addition to the average per person per day intake of VA412Iu meal, do not eat enhanced VA oil. Both groups were observed for 40 days, at the beginning and end of the experiment, each measured dark adaptation function. There was no significant difference between the control group and the control group (P> 0.05). China’s diet is based on the main plant foods, dietary VA deficiency, to promote the strengthening of VA vegetable oil, economical and feasible.
