Measurement of LDL cholesterol levels was done before and after 14 days given avocado juice. Data analysis used paired T test to analyze differences in blood LDL cholesterol levels before and after being given avocado juice.
Results: The results are average value of blood LDL cholesterol levels on pretest was 137.1 mg / dL and posttest was 128.25 mg / dL with mean reduction was 8.85 mg / dL.
