Adopting a low glycaemic index (GI) diet improves metabolic parameters in individuals with insulin resistance or type 2 diabetes, including lowered HbA1c, improved glucose tolerance, and reduced insulin resistance.

To manage blood sugar and insulin resistance, prioritize foods with a low glycaemic index (GI). This includes legumes, pasta, sourdough bread, and barley. These foods release glucose slowly, reducing insulin spikes. Be aware that common staples like white bread and potatoes have high GIs, so look for specific low-GI alternatives or processing methods (like high-amylose grains) when possible.

GoodSupportsHIGH confidence
Accumulating data indicate that a diet characterized by low glycaemic-index (GI) foods not only improves certain metabolic ramifications of insulin resistance, but also reduces insulin resistance per se.
