title: Effect of the consumption on buriti oil on the metabolism of rats induced by iron overload.
abstract: OBJECTIVE
  To compare the effect of the consumption of buriti oil and soybean oil on the metabolism of rats under stress induced by iron overload.
  
  
  METHODS
  A total of 28 rats were randomized into control groups who consumed diet added of soybean (CS) or buriti oil (CB) and gavage with saline and two experimental groups who consumed diet added of soybean (ES) or buriti oil (EB) and daily gavage with iron II sulfate as stress inducer. The fatty acid profile of diets was analyzed. Body weight and diet consumption were evaluated every two days. The lipid profile and liver weight of animals were evaluated at the end of the experiment.
  
  
  RESULTS
  Diet added of soybean oil showed higher percentage of polyunsaturated fatty acids (45.6%) and diet with buriti oil was rich in monounsaturated fatty acids (66.9%). There were no differences in food intake, total cholesterol, HDL-cholesterol and LDL-cholesterol among groups (p > 0.05). However, animals fed with diet supplemented with buriti oil showed intermediate triglyceride levels (CB: 65 mg/dL; EB: 68.7 mg/dL) compared to ES group (102.5 mg/dL). The liver of rats from the CS group had higher weight (2.06 ± 0.2 g) compared to the CB group (1.56 ± 0.1 g).
  
  
  CONCLUSIONS
  Buriti oil consumption was able to minimize some changes related to iron overload.
