Eating healthily helps to control blood glucose levels and weight, preventing the onset of type 2 diabetes. The Department of Endocrinology at Singapore General Hospital (SGH) shares tips on how to have a healthy diet and prevent diabetes.
By 2030, the number of Singapore residents above 40 with diabetes is projected to increase by another 200,000 from about 400,000 today. As there is no cure for diabetes, keeping it under control is crucial.
In diabetes, the pancreas produces too little or ineffective insulin, a hormone which lets body cells use blood sugar for energy. Diabetics have higher blood sugar levels than normal (hyperglycaemia). There are two major types of diabetes: type 1, often diagnosed in childhood, and type 2, largely caused by an unhealthy lifestyle and diet.

Treating diabetes
"There is
no cure for diabetes, which is a lifelong disease," according to doctors at the
Department of Endocrinology at
Singapore General Hospital (SGH), a member of
SingHealth group. It can be controlled through various means such as a healthy diet, regular exercise, oral medication to balance blood glucose, insulin injections, and regular monitoring and control of blood sugar.
To prevent type 2 diabetes:
-
Follow a proper diet. Besides insulin and medicine, eating healthily helps to control blood glucose levels and weight.
-
Maintain a healthy weight. If overweight, losing a few kilos can reduce the risk of diabetes.
-
Get regular exercise. Exercise helps to control weight and also keeps the heart healthy.
