Male Sprague-Dawley rats (n=6 per group) were fed semi-purified diets containing 5% oil with or without cholesterol (Ch) or garlic (G) for 21 days. In the C fed rats, addition of dietary Ch, there was a redistribution of Ch from HDL to LDL class. In contrast, 1% Ch added to O diets produced a 4-fold increase in serum Ch compared with levels in rats fed O without Ch. This was associated with a 14-fold increase in LDL Ch and a 7-fold decrease in HDL Ch levels. Addition of 2% G had no effect on the distribution of serum Ch between HDL and LDL Ch in C+Ch fed rats, but in O+Ch fed rats, G halved the increase in serum Ch and LDL and attenuated the decrease in serum HDL by 23%. The results suggest that the dietary O regulated the levels of serum in Ch loaded rats. G attenuated serum Ch in O fed rats and decreased serum risk factors, both total Ch and LDL-C ratio and LDL-Ch/HDL-Ch ratio.
