Carbohydrate Metabolism

Once the food is start digesting, the first nutrient that is extracted out is glucose or sugar and released into the blood stream for energysing the body cells calles as glucose metabolism.

What are carbohydrates?

Carbohydrates are sugars and starches, provides energy to the body needed for its various activities. Energy can also been supplied by fats we eat. Some common carbohydrate sources are bread, potatoes, rice, pasta, cereals and sugars.
What is Glucose / Carbohydrate metabolism

Digestion and start of glucose metabolism
Once the food we ate reaches stomach, glucose metabolism begins with first glucose is separated and released into the blood stream and thus glucose level in blood rises.

Insulin secretion by pancreas
Pancreas response to rising blood glucose level by immediately releasinginsulin, proportional to the level of glucose in blood. Human Insulin is a chemical messenger (a hormone).

Glucose consumption by body cells
Insulin in blood comments
liver to stop releasing glucose into the blood-stream
body cell to start consuming glucose. 

Glycogen storage by the liver
After necessary glucose consumption is completed and if there is any excess glucose still available in the blood-stream then liver start converting this excess glucose in to glycogen and stored it for future requirements.

Glycogen to glucose conversion
If we are not having our food in time and the body cells needs energy then liver converts back stored glycogen in to glucose and releases it in to the blood stream.

Glucose metabolism and diabetes
If there is any problem or defect in the glucose metabolism; whether it is glucose absorption, insulin secretion, glucose utilization, glucose storage or releasing stored glucose. This minor defect in glucose metabolismwill slowly develop diabetes.

Diet For Diabetes Mellitus

Now, We will try to explain about how to manage the diet for Diabetes Mellitus. Diabetes mellitus is a disease that characterised by hyperglycaemia, whether it is cause by deficiency of insulin in the human body or diminished effectiveness of insulin it self. There are many cases why the insulin become inactive and hence induces hyperglycaemia, for example due to over production of other hormones which are antagonistic to Insulin such as glucagon, hormones of the pituitary, adrenaline and thyroid. Also due to increased production of substances which inactivate insulin (insulinase and insulin antagonists present in plasma. The disease is chronic and affects the metabolism of carbohydrate, protein, fat, water and electrolytes. Diabetic Diet for diabetics patient is simply a balanced healthy diet which is vital for diabetic treatment, but sometime many people are they don't understand that these diet consist only diabetic foods.

Checking Blood Sugar Levels

If you are a diabetic then checking blood sugar levels is a vital part of your daily regimen. It is important regardless of which form of diabetes you may have but especially so if you are suffering from Type 1 diabetes. This is because in Type 1 diabetes you need to furnish the correct amount of insulin yourself as the body is no longer capable of performing this function. Glucose is our body’s main fuel supply. However, if there is too much or not enough glucose in your blood it can have a negative impact on the body. This is why it is so important for a diabetic to monitor blood sugar levels. Symptoms of High Blood Sugar If a test reveals there is too much sugar in the blood you can develop hyperglycemia. In someone without diabetes, the hormone insulin helps maintain normal blood sugar levels. However, diabetics aren’t that lucky so having too much or not enough sugar can spell trouble because their bodies stopped producing insulin, stopped producing enough of it or their bod
