The Claim

Higher dietary glycemic index is not meaningfully associated with heart failure incidence in middle-aged and elderly Swedish women, as the highest versus lowest quartile showed no statistically significant difference in risk (RR = 1.12, 95% CI: 0.87–1.45, p for trend = 0.31), even after adjusting for multiple confounders.

What the research says

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

Eating foods that raise blood sugar quickly doesn’t seem to increase the risk of heart failure in middle-aged and older Swedish women, based on a study that found no clear link between the two.

What the research says

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

    This study looked at whether eating foods that spike blood sugar quickly (high glycemic index) leads to more heart failure in older Swedish women — and found no clear link. So the claim that it doesn’t matter much is backed up by the data.
