Abstract
The objective of this study was to determine the effect that different dietary fatty acids would have on the fatty acid composition of adipose tissue. Thirty adult rabbits were starved 3–4 wk to deplete adipose tissue stores. They were then refed five different fats (linseed, rapeseed, cocoa butter, palm, and safflower oils) to regain initial body weights. The fatty acids of the adipose tissue, in general, reflected the diet. Positive correlations between the amount of the five commonly consumed fatty acids (palmitic, stearic, oleic, linoleic, and linolenic acids) in the diet and their deposition into the adipose tissue were observed. All polyunsaturated and monounsaturated fatty acids were well incorporated into the adipose tissue, even linolenic acid. The deposition of dietary saturated fatty acids (ie stearic acid) was limited. Our data showed that the fatty acids of dietary fats may greatly affect adipose fatty acid composition. Thus, adipose stores of essential fatty acids can be greatly augmented by diet.
