Effect of red pepper Capsicum annuum var. conoides and garlic Allium sativum on plasma lipid levels and cecal microflora in mice fed beef tallow.
Antihyperlipidemia or hypocholesterolaemic and antibacterial activities of red hot pepper and garlic are well known. To determine the effect of the dietary spices ingested to suppress blood lipids on the intestinal condition, we examined plasma lipid levels and cecal microflora in mice that were fed diets containing 19% (w/w) beef tallow and 2% red pepper Capsicum annuum var. conoides 'Takanotume' (RP) or garlic Allium sativum 'White' (GP) for 4-weeks. Plasma triacylglyceride level was suppressed by the spices. RP lowered cecal bacteroidaceae, a predominant bacterial group (from 9.4 to 9.0 log CFU/g), bifidobacteria (from 8.7 to 7.6 log CFU/g), and staphylococci. Although GP increased the cecal weight including their contents, significant differences were not shown in the cecal microflora. These results suggest that RP can affect the intestinal condition and host health through the disturbance of intestinal microflora.
