Foods to Avoid With Diabetes (Especially When Blood Sugar Is High)
These foods are rated unsafe at the poorly-controlled level — they tend to drive a rapid, pronounced rise in glucose. That does not always mean "never", but they call for real caution, smaller portions or a better-controlled starting point. Where the source flags a food as not recommended in any amount, we say so plainly.

Want help turning numbers like these into a dosing decision? Flona estimates carbs and supports your insulin decisions every day.
Why This Matters
After a meal, carbohydrate is broken down to glucose and absorbed into the blood; insulin then helps move it into cells. Foods that release glucose slowly produce a smaller, steadier rise. HbA1c reflects your average blood sugar over roughly the past three months. It is the anchor for the three control levels used throughout this site.
Turn food decisions into confident ones with Flona
Flona is your daily companion for insulin decisions — basal, rapid-acting, mixed or meal-based — and for estimating carbs at a glance. It is guidance to support you day to day, not a replacement for advice from your physician or diabetes care team.
Medical disclaimer: This article is for general education and is not medical advice. Ratings and portions are estimates derived from nutritional composition, not measurements of your own glucose response; individual responses vary. If you take insulin, confirm carbohydrate amounts against a nutrition label before dosing. Always follow the guidance of your own physician or diabetes care team.
How these ratings are produced: our safety estimate is derived from each food's nutritional composition — carbohydrate content, fibre, food category and physical form (liquid or solid) — combined with established diabetes nutrition principles and a realistic serving size. They are estimates for planning, not measurements of your own response and not a prescription. Individual responses vary considerably, so always follow your own clinician's advice.
