Blood Sugar Levels
The blood glucose level (BGL) is a way of measuring the amount of sugar that is present in our blood stream. Our bodies function best when the BGL is kept within a certain range, a range that is fairly narrow. If the level gets too high, too often it is possible that our health will be compromised.
The body regulates BGL through the release of hormones; insulin will lower and glucagon and cortisol will help to raise it. Typically it is raised blood sugar that is the problem; often as a result of a diet that is high in sugary foods, accompanied by a lifestyle that does not feature sufficient exercise to burn off the sugar. This continually exposure to high levels of sugar will lead to huge stress on our regulatory system and potentially can lead to the onset of Type II diabetes.
So what are the symptoms?
|Urinating more than normal||Feeling very thirsty||Feeling very tired|
|Unexplained weight loss||Cuts/wounds that are slow to heal||Itching around genitals|
|Blurred vision||Excessive hunger pangs||Tingling or numbness in hands or feet|
In addition to calories maybe a key thing to think about when looking at your diet is the glycaemic index.
The Glycemic Index is a way of ranking carbohydrates based on the speed at which they are broken down and converted to glucose in the body. A high glycaemic index food is one that converts quickly – typically the sorts of foods we reach for when we want a quick burst of energy e.g. sweets, chocolate, etc The problem is that the quick burst of energy will lead to a sudden spike in blood glucose level. We would be better to look at energy sources with lower glycaemic indexes. These foods release energy much more slowly and therefore do not challenge insulin in such a dramatic fashion and our BGL stays within an optimal range. In simple terms your health and your performance will benefit by keeping blood sugar relatively constant.
