Dietary Fibers and Glycemic Load, Obesity, and Plasma Adiponectin Levels in Women With Type 2 Diabetes
Key result
Higher dietary cereal fiber intake was associated with 24% higher plasma adiponectin concentrations (P for trend=0.002), while higher glycemic load was associated with 17% lower levels.
Why the study?
Are dietary fibers and glycemic load associated with plasma adiponectin levels in women with type 2 diabetes?

902 women with type 2 diabetes from the Nurses' Health Study

Implication
Should not yet change dietary advice in T2D; leaves open causal effects on adiponectin and cardiometabolic outcomes.

Main Result
p-value: p=0.002
Higher intake of cereal fiber and lower dietary glycemic load are associated with higher circulating adiponectin concentrations in women with type 2 diabetes, independent of obesity status.
Cite This Study
Qi et al. (2006) conducted a cross-sectional in Type 2 diabetes (n=902). Dietary fibers and glycemic load vs. Lowest quintiles of intake was evaluated on Plasma adiponectin concentrations (p=0.002). Higher dietary cereal fiber intake was associated with 24% higher plasma adiponectin concentrations (P for trend=0.002), while higher glycemic load was associated with 17% lower levels.
