  1. All values are means ± SEM. Intakes were estimated from three-day food records by using CAN-pro (Korean Nutrition Society, Seoul, Korea). Intakes of test products were included in the analysis. SFA saturated fatty acids; MUFA monounsaturated fatty acids; PUFA polyunsaturated fatty acids.
  2. #Tested after log transformation.
  3. *Significantly different within a group, P < 0.05 (paired t-test).
  4. §Comparison between the placebo and the Chlorella group at week 0 and week 4, respectively (Student’s t-test).
