The influence of dietary fat on the composition of perirenal adipose tissue was studied in Wistar rats fed three experimental semisynthetic, isocaloric diets containing different qualities of fat (olive oil, butter and medium chain triglycerides + corn oil). Under these experimental conditions, the saturation index reflects the percentage of fatty acids supplied by each diet; this index was highest in animals fed the diet containing butter and lowest in the group in which olive oil was the dietary fat source. The amount of linoleic acid (the major component of the diunsaturation index) supplied by the diet is directly paralleled by levels of this fatty acid in perirenal adipose tissue, whereas the monounsaturation index in adipose tissues, considered an indicator of the dietary supply of monounsaturated fatty acids in the rat, failed to show a clearly proportional relationship between intake and perirenal adipose tissue levels.
