Understanding Bread Units

What are Bread Units?

Bread Units (BU) are a measurement system used primarily in diabetes management to help calculate carbohydrate intake. One Bread Unit equals approximately 12 grams of carbohydrates.

How to Calculate Bread Units

Bread Units = Carbohydrates (g) ÷ 12

For example: A food with 24g of carbohydrates = 24 ÷ 12 = 2 Bread Units

Using Bread Units for Diabetes Management

Meal Planning

Most people with diabetes aim for 3-4 Bread Units per meal and 1-2 Bread Units per snack. This helps maintain stable blood sugar levels throughout the day.

Insulin Dosing

Many people use the carbohydrate-to-insulin ratio method, where they take a certain amount of rapid-acting insulin for each Bread Unit consumed. This ratio is individualized and should be determined with your healthcare provider.

Important Note

Always consult with your healthcare team before making changes to your diet or insulin regimen. Bread Units are a tool to help with consistency, but individual responses to carbohydrates can vary.
