What this means
As a low-GI food, sourdough bread releases glucose slowly, so it tends to produce a gentle, sustained rise rather than a sharp spike, easier on your time in range.
Glycemic index measures speed; glycemic load measures the impact of the amount you actually eat. The best read is your own: a post-meal reading shows how your body handled it.
