Consumption advice

Eat the whole apple with its skin, because the skin holds much of its fibre and antioxidants.

Best preparation methods

Pair apple slices with a spoonful of peanut butter or a handful of almonds for a balanced snack, and skip apple juice.

Important Nutritional Note

For people with diabetes or insulin resistance, it is always recommended to consider the total glycemic load (GL) of the meal rather than relying on the glycemic index alone.
