What Should People with Diabetes Eat?

What Should People with Diabetes Eat?

Did you know?

Optimal blood glucose control is important to prevent potentially serious complications that are associated with diabetes. Consuming an appropriate diet is key to this.

What should people with diabetes eat?

  • A healthy diet, as recommended by the Australian Dietary Guidelines
  • Consume meals at regular times1
  • Some people with diabetes will require additional snacks between meals depending upon their diabetes medication and blood sugar control
  • Choose lower fat alternatives (particularly low saturated fat)1
  • Choose low glycaemic index options 2

What is glycaemic index?

The glycaemic index is a ranking of carbohydrates according to how quickly they elicit a rise in blood glucose levels. Low glycaemic index foods produce a smaller rise in blood sugar levels, providing a sustained source of energy and have been linked with reducing heart disease and are the preferred source of carbohydrate foods for people with diabetes 3.
