The reality is more nuanced: potatoes are not inherently incompatible with a diabetes-friendly diet, but how they are prepared, what else is eaten alongside them, and what quantity is consumed all matter significantly. Understanding the actual glycemic biology of potatoes — and the evidence on how different preparation and pairing choices affect blood glucose response — makes for a much more useful framework than a blanket prohibition.
