Foods to avoid with Insulin-Dependent Diabetes
For insulin-dependent diabetes, what matters is how quickly an ingredient raises blood glucose and how easily it can be dosed for. Maltose, malt extract and high-fructose corn syrup are flagged for fast glycaemic impact, while some sweeteners carry caution over effects on insulin response.

How diet fits with insulin-dependent diabetes
Why speed matters
For people who take insulin, what matters about a food is how much carbohydrate it contains and how quickly it raises blood glucose, because insulin doses are matched to what is eaten. Carbohydrate counting is a common meal-planning approach: insulin at meals is typically based on the number of carbohydrates eaten and an individual ratio set by your care team. That is why this guide rates sweeteners and starches such as maltose, malt extract and high-fructose corn syrup by how fast they raise glucose.
The same sugar can help and harm
The National Institute of Diabetes and Digestive and Kidney Diseases advises treating a low blood glucose with 15 to 20 grams of fast-acting carbohydrate, such as glucose tablets or gel, rechecking after 15 minutes and repeating if needed. Fast-acting sugars are therefore the right tool for a low and a poor choice as an everyday sweetener, which is why some entries carry a stricter rating in one state than in the other.
Other points
Celiac disease and autoimmune thyroid disease occur more often in people with type 1 diabetes, so some gluten and iodine entries are relevant too. Sweeteners with no sugar can still carry cautions about gut effects or insulin response, and the entries explain which. Children and people who use insulin pumps or multiple daily injections have different needs, and a diabetes care team or dietitian can set the right approach.
How to use this guide
The ratings are general information based on published guidance, and they cannot take the place of your own glucose readings and insulin plan. Check labels for total carbohydrate and added sugars, and talk to your care team before changing how you eat.
Questions to ask your care team
Useful questions include what your insulin-to-carbohydrate ratio is, how to count carbohydrates in mixed foods and restaurant meals, what to carry for lows and how much to take, and how exercise changes your needs. If you use a continuous glucose monitor or pump, ask how to adjust for foods that raise glucose quickly or slowly, and how to handle foods with sugar alcohols or sweeteners.
