大量食用饼干和咸味零食会影响人体健康。采用气相色谱法测定了19种饼干和10种咸味小吃的脂肪酸组成。棕榈酸在79%的饼干中占主导地位，在咸味零食中占总饱和脂肪酸（SFA）的55%以上。饼干中反式脂肪酸含量较低（占总脂肪酸的0.86%），咸味零食中反式脂肪酸含量最高（占总脂肪酸的7.94%）。结果表明，每天摄入大量的脂肪酸和反式脂肪酸，这可能对健康产生不利影响。我们强烈建议学生改变饮食习惯，选择适当的食物，以预防患上慢性疾病。此外，食物的FA概况的知识可以帮助建立针对这一人群的健康计划。(C)2014爱思唯尔有限公司版权所有。
High levels of biscuit and salty snack consumption have an effect on human health. This aim of this study was to determine the fatty acid (FA) composition of 19 different biscuits and 10 types of salty snacks by gas chromatography. Palmitic acid was predominant in 79% of biscuits and represented more than 55% of the total saturated fatty acids (SFAs) in salty snacks. Low concentrations of trans fatty acids were observed in biscuits (0.86% of total FAs), and the highest values were observed in salty snacks (7.94% of total FAs). The results indicate a high daily intake of SFAs and trans fatty acids, which may have an unfavourable effect on health. Changes in dietary habits and appropriate food choices by students are strongly recommended to prevent the risk of chronic disease. Furthermore, knowledge of the FA profile of food can help to establish health programs targeted to this population. (C) 2014 Elsevier Ltd. All rights reserved.
