Objectives:
Controversy persists regarding the effect of mixtures of conjugated linoleic acids (c9,t11- and t12,c10-CLA) in fasting blood glucose (FBG) and waist circumference (WC) in humans. Therefore, this review article (meta-analysis) has been conducted.
Does CLA reduce fasting blood glucose (FBG) and waist circumference (WC) in humans?
Study design:
This review article included 32 randomized clinical trials.
Results and conclusions:
The investigators found subgroup analysis showed that taking CLA supplement did not significantly influence fasting blood glucose [SMD = 0.075 mg/dL, 95% CI = -0.099 to 0.249, p = 0.399].
The investigators found subgroup analysis showed that taking CLA supplement reduced non-significantly waist circumference with 0.149cm [SMD = -0.149cm, 95% CI = -0.522 to 0.225, p = 0.435].
The investigators found foods enriched in CLA also showed no significant effect on fasting blood glucose [SMD = 0.126 mg/dL, 95% CI = -0.100 to 0.352, p = 0.274].
The investigators found foods enriched in CLA also showed no significant effect on waist circumference [SMD = -0.233cm, 95% CI = -0.625 to 0.159, p = 0.244].
The investigators concluded that c9,t11- and t12,c10-CLA administered as a supplement or used to enrich foods does not reduce fasting blood glucose (FBG) and waist circumference (WC) in humans.

Conjugated linoleic acids (CLA) are a family of isomers of linoleic acid found mostly in meat and dairy products derived from ruminants. An average daily diet supplies 15-174mg of conjugated linoleic acid.
