颊细胞脂质分析已被建议作为一种非侵入性的方法，用于监测人类饮食中的脂肪酸组成。在一项旨在确定该方法有效性的初步研究中，从食用低脂肪（20%卡路里）饮食的受试者中收集脸颊细胞样本，该饮食由P/S比为1.0或0.3的脂肪酸组成。无论是总脂，也不极性脂脂肪酸在脸颊细胞一贯反映的P/S比的饮食。然而，有趋势，特别是在非极性脂质，这表明颊细胞脂肪酸比可能是有用的监测的脂肪酸组成的饮食。高P/S比（1.0 vs 0.3）组颊细胞脂质中18∶1/饱和脂肪酸比值较低，18∶2/20∶4、18∶2/18∶1和18∶2/18∶0脂肪酸比值较高。
Analysis of cheek cell lipids has been suggested as a noninvasive method for monitoring the fatty acid composition of diets in humans. In a pilot study conducted to determine the validity of the method, cheek cell samples were collected from subjects consuming a low fat (20% of calories) diet consisting of fatty acids with either a 1.0 or 0.3 P/S ratio. Neither total lipid nor polar lipid fatty acids in cheek cells consistently reflected the P/S ratio of the diets. However, there were trends, particularly in the nonpolar lipids, suggesting that cheek cell fatty acid ratios might be useful for monitoring the fatty acid composition of the diets. The diet with the higher P/S ratio (1.0 vs 0.3) consistently resulted in cheek cell lipids with lower ratios of 18∶1/saturated fatty acids and greater 18∶2/20∶4, 18∶2/18∶1 and 18∶2/18∶0 fatty acid ratios.
