A stable blood sugar - why is it important?

What is blood sugar?

Your body uses sugar in the form of glucose to produce energy for your body.

The sugar mainly comes from food but can also be provided by your liver. Glucose provides energy to body parts such as the muscles, the brain and even red blood cells.

Our bloodstream delivers sugar to our body’s tissues. Providing energy in the form of glucose to our body is vital for health, but ensuring our blood sugar does not drop too low or too high is equally important.

A stable blood sugar providing consistent energy helps to prevent sugar cravings and reduces the risk of health complications, like kidney disease, eye disease and comas.

People with diabetes are at a higher risk of hypoglycaemia (low blood sugar) and hyperglycaemia (high blood sugar). A healthy lifestyle accompanied by medication, if needed, will help to keep blood sugar levels stable. These include exercise, managing stress, a balanced diet, and getting enough rest.


Diet tips that can help to maintain a stable blood sugar:

  • Have regular meals and snacks spread evenly throughout the day.

  • Always balance carbohydrates with protein, vegetables and healthy fats.

  • Have lower Glycaemic Index (GI) starches such as whole grains in controlled portions.

  • Avoid foods that may spike your blood sugar due to the high sugar content, such as cold drinks, sweets and processed foods.

  • Balance energy intake with exercise and keeping to an active lifestyle.
