AA, et al. – Based on the results observed in this study, it can be
concluded that the consumption of Lactobacillus bulgaricus and
Streptococcus thermophilus (LBST) yogurt indicates either favourable or
neutral effects on metabolic risk markers when compared with a control
treatment in controlled research settings. Randomised controlled trials
(RCTs) exploring the impact of LBST yogurt consumption on metabolic risk
markers of chronic diseases are scarce and presented considerable
variation in methodologies making comparison between studies difficult.
Methods
- In this study, the researchers performed a systematic search in July 2016 in the scientific databases PubMed, EMBASE and The Cochrane Library.
- Included studies were RCTs that assessed the effect of consuming yogurt containing LBST as a treatment, and that assessed at least one metabolic risk marker for chronic diseases compared with a control diet or a diet supplemented in another food/ingredient in healthy or chronically ill adults.
- 7 RCTs including 278 participants were incorporated in the review.
- Studies were conducted in the USA, France, Spain, Iran and Canada.
- 5 studies were undertaken in healthy adults, and 2 were conducted among lactose malabsorbers.
- All studies examined changes in blood lipids and glucose homoeostasis, with different doses of yogurt, durations of the supplementation and risks markers evaluated.
Results
- Researchers found that consumption of LBST yogurt significantly decreased total cholesterol concentrations, ratio of total cholesterol to HDL-C and plasma glucose compared to a control yogurt-free diet or diet supplemented in another food/ingredient in two out of the seven studies.
- The greater part of included RCTs presented high to unclear methodological risks of bias, which brings up issues about the validity of their findings.
