Dietary Effects of Frankfurters with Added Beef Fat and Peanut Oil

Beef frankfurters containing 12% or 29% fat, either all beef fat or 40% beef fat plus 60% peanut oil, were fed to rabbits, resulting in a significant increase in serum cholesterol and triglyceride levels compared to rabbits fed rabbit chow. The absolute increase and rate of increase in triglyceride levels were affected by the amount of fat but not by the presence or absence of peanut oil. Cholesterol levels were not significantly different in animals fed frankfurters containing 12% or 29% beef fat except at 4 wk; the inclusion of peanut oil in the frankfurters significantly lowered serum cholesterol levels .at 5 and 6 wk. Overall, frankfurters containing 12% final fat with 60% peanut oil substitution had the least hyperlipidemic effect.
