Food facts

The oats, syrup, honey, cranberries and milk are the main sources of carbohydrate in this breakfast and the value has been provided for those who have been trained in insulin adjustment.

We have used dried cranberries and omitted the nuts to keep this recipe low in potassium and phosphate. The potassium and phosphates within this dish can be lowered further by using a plant-based milk such as soya, rice or almond (opt for unsweetened and organic versions) in place of the dairy semi-skimmed milk. You many have advised to restrict your milk intake over the day. If this is the case, remember to deduct 150ml from this recipe from your daily allowance. If you have been prescribed a phosphate binder, ensure you take them with this breakfast.

Dairy milk is a good source of protein. If you have been advised to eat plenty of protein but prefer plant milk, then opt for soya milk.

Use gluten-free oats.

Replace the dairy milk with a non-dairy alternative and use maple syrup in place of honey.

This homemade granola is lower in fat and sugar than a shop-bought alternative.

Store in an airtight container for 2-3 weeks.

If you need more fluid, try adding a splash of water.
