Diabetes food quiz
A quick, friendly way to test your instincts. A common food appears — you guess whether it’s a smart choice for blood sugar or one to go easy on, and then you get a plain-English explainer for why. There are several hundred foods in the deck, from fruit and bread to curries, takeaways and drinks. Nothing here is a verdict on you or your cooking — it’s a gentle way to learn what moves blood sugar and what doesn’t.
Foods are sorted into three traffic lights: Enjoy (build meals around these), In moderation (fine in sensible portions), and Best limited (small and occasional). For the moderation foods, either guess counts as right. This is general information tied to the foods guide, not personal dietary advice — portions and your own body matter, and a dietitian can tailor it to you.
Smart choice for blood sugar, or go easy?

The food ratings and explainers on this page — hundreds of them — were compiled with the help of AI tools and may contain errors, oversimplify, or be out of date; individual responses to foods vary, and portion size and how a food is cooked and combined change its effect. They are shared in good faith for general interest only, and are not medical, nutritional or dietary advice. Nothing here is a substitute for a doctor, diabetes nurse or registered dietitian — especially if you take insulin or other glucose-lowering medication. See the foods guide for the sourced version, and check anything important against the primary sources cited there.
