Effect of fermented milk containingLactobacillus acidophilusandBifidobacterium longumon plasma lipids of women with normal or moderately elevated cholesterol

Abstract

This study aimed to evaluate the effect of milk fermented withLactobacillus acidophilus145 andBifidobacterium longumBB536 on plasma lipids in a sample of adult women. A double-blind, placebo controlled, cross-over study (two periods of four weeks each separated by a 1-week washout period) was performed in 34 women, aged between 18 and 65 years. Group A consumed 125 g fermented milk three times a day for the first 4 weeks while group B consumed regular yoghurt under the same conditions. (Groups A and B switched products for the second treatment period). Women taking the test product with a baseline total cholesterol above 190 mg/dl showed a significant reduction in LDL cholesterol. HDL cholesterol was also reduced by the test product. We conclude that the fermented milk may help to reduce LDL levels in hypercholesterolemic adult women.
