title: Fatty acid profile of biscuits and salty snacks consumed by Brazilian college students.
abstract: 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.
