Understanding carbohydrate exchanges

One exchange = roughly 15 grams of carbohydrate

The exchange system simplifies carbohydrate counting by grouping foods with similar carbohydrate content. This makes meal planning easier and helps you maintain consistent carbohydrate intake.

For more detailed information, the [Diabetes Victoria 'Carbohydrate counting in exchanges' booklet] can be used alongside this fact sheet.

Reading food labels

Food labels provide the most accurate information for counting carbohydrates. The Nutrition Information Panel (NIP) shows exactly how many grams of carbohydrate are in a food or drink.

Important reminder: Don't confuse a "serving" with an "exchange". A serving is the manufacturer's chosen serve size and may not equal one exchange.
