Eating a balanced diet with plenty of different food groups, vitamins and minerals is important for everyone, and is also an integral part of maintaining your target blood glucose levels if you have diabetes.
Diet and poor nutrition are important risk factors for developing type 2 diabetes too [1, 2].
This article will cover the basics of balanced eating when you have diabetes, what foods can make up a varied diet, and what foods to be a little more aware of.
Eating with diabetes
This article was written using research that mostly focuses on type 1 and 2 diabetes. For all people with diabetes, it is important to discuss any planned changes to your diet with your diabetes team or ensure you have done some research to help you understand more about your choices.
No two people living with diabetes are the same, so there isn’t a one-size-fits-all meal plan or diet for everyone. You will have your own blood glucose targets to try and stay within, and these can vary depending on your age, health and other factors . Keeping your blood glucose in range over the long term helps delay or prevent complications such as heart disease, vision problems, or kidney disease [1, 3].
To stay within your target blood glucose range, you might think that you have to stop eating certain food, but this isn’t necessary, you can still eat what you want and enjoy, it’s just about balance and moderation .
