The metabolic syndrome (MetS) is a cluster of conditions including central adiposity, dyslipidemia, hypertension, and hyperglycemia. We conducted a study of 142 healthy older adults aged 60–88, examining fat quality as measured by diet history questionnaire, and plasma and adipose fatty acid composition as predictors for components of MetS. Plasma 16:0, 16:3n4, 18:1n9, and 20:1n9 and dietary saturated fat, monounsaturated fat, and cholesterol predict for having MetS. Dietary monounsaturated fat increases, while adipose 16:1n7 and 18:4n3 decrease, in subjects with increasing numbers of MetS features. Adipose 16:0 is correlated with each feature of MetS. Plasma saturated and monounsaturated fatty acids were positively correlated, while plasma polyunsaturated fatty acid composition was negatively correlated, with triglyceride levels. This study demonstrates several important relationships between the features of metabolic syndrome and fatty acid quality in the diet, plasma, and adipose tissue. Further research should be conducted to determine if these relationships are the result of differences in dietary intake or fatty acid metabolism.
