By Dr. Adarsh K S,


Glucose is an important source of fuel for our body. Insulin, a hormone produced by the pancreas, is a key regulator of blood glucose levels. Insulin helps the body cells to take up glucose from the bloodstream and thereby normalises the glucose levels in the blood (<100 mg/dL in fasting state). Diabetes mellitus (DM) is a chronic condition, characterised by raised blood glucose levels than normal. When our body does not produce enough insulin, glucose is not transported to cells from the bloodstream efficiently. High blood glucose levels, over time, can adversely affect your heart, vision, nervous system, kidney, etc. “India is regarded as the world capital for diabetes, accounting for >69.2 million cases. We Indians are at a higher risk of developing diabetes as compared to the Western population due to genetics. This coupled with unhealthy food habits, sedentary lifestyle and high stress levels are the key driving force for the alarming diabetes rates in our country. Awareness about the condition, a healthy lifestyle and regular check-up can go a long way in reducing the morbidity and mortality related to diabetes.

Diabetes can be classified as 3 types, primarily

Type 1 diabetes An autoimmune condition not related to lifestyle, where the body does produce sufficient insulin and the patient requires insulin injections for the rest of his life.

Type 2 diabetes occurs when our body is not able use insulin effectively. This develops later in life. Excess weight gain and a sedentary lifestyle are major causative factors for type 2 diabetes

Gestational diabetes develops during pregnancy and is a risk factor for several complications in the mother and the new born baby.

Choose food rich in monosaturated fats (MUFA) and polysaturated fats (PUFA) good for heart health. Food rich in MUFA and PUFA include olive oil, seeds, nuts, sea fishes, ghee, etc.
  • Follow plate method: Half of your plate should be filled with non-starchy vegetables, such as spinach, cabbage, tomatoes, etc. One-fourth should be protein such as chicken, fish, tofu, etc. the rest one-fourth should be whole-grain item, such as brown rice, or a starchy vegetable, such as green peas.
  • Create a meal plan: It is always a good idea to create a meal plan with the help of a dietician to achieve your target blood glucose levels. A dietitian can also help you in understanding and interpreting food labels. In case you are on insulin, a dietician can teach you how to adjust insulin dose depending on your food intake.
