The Claim

Higher dietary glycemic index is weakly associated with an increased risk of coronary heart disease, with a 4% higher risk per 5-unit increase in glycemic index, but this association is observed only in continuous analyses and not in quintile comparisons.

Source: Glycemic index, glycemic load, and risk of coronary heart disease: a pan-European cohort study.

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 spike your blood sugar quickly might slightly raise your risk of heart disease, but only if you look at the numbers in a certain way—when you group people into categories, the link disappears.

What the research says

1 study
  1. Study: Glycemic index, glycemic load, and risk of coronary heart disease: a pan-European cohort study.

    This big study found that eating foods that spike blood sugar more (higher GI) slightly increases heart disease risk — but only when looking at small continuous changes, not when grouping people into big categories. That’s exactly what the claim says.
