The Claim

Among middle-aged and elderly Swedish women, the association between dietary glycemic load and heart failure does not differ significantly by BMI category, as the risk ratios for heart failure associated with dietary glycemic load are similar between overweight and normal-weight individuals (overweight: RR = 1.47, 95% CI: 0.84–2.58; normal weight: RR = 1.11, 95% CI: 0.62–2.00; p for interaction = 0.55).

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

For middle-aged and older Swedish women, eating foods that raise blood sugar quickly doesn’t seem to affect heart failure risk any more for overweight women than for women who are normal weight — the risk is about the same in both groups.

The association between dietary glycemic load and heart failure does not differ significantly between normal-weight and overweight middle-aged and elderly Swedish women, as the risk ratios were similar across BMI groups (overweight: RR = 1.47, 95% CI: 0.84–2.58; normal weight: RR = 1.11, 95% CI: 0.62–2.00; p for interaction = 0.55).

What the research says

1 study
  1. Study: Dietary Glycemic Index, Dietary Glycemic Load, and Incidence of Heart Failure Events: A Prospective Study of Middle-Aged and Elderly Women

    The study looked at whether eating high-sugar foods affects heart failure risk differently in thin vs. overweight women, and found no real difference — just like the claim says.
