I went into an organic store looking for dextrose once and the lady flipped out and told me that it causes diabetes. She basically gave me an evil eye forcing me out of the store. Any truth to this? Also, is dextrose just a transporter of protein or what exactly does it do post workout?
IF that is what she said then her understanding of how important glucose is and its function within the body needs changing.
As I mentioned,
glucose is your body's main source of energy.
It is directly involved in the production of ATP (Adenosine triphosphate). You have probably heard of ATP when someone is talking about creatine. When ATP is transformed into ADP (Adenosine diphosphate) it releases energy. Your body doesn't have an endless supply of ATP and so you are only able to exert yourself for a short period of time. When Creatine Phosphate is introduced into your body in the form of a supplement, it transforms the ADP back into ATP and thus provides you with an additional energy source.
But back to the glucose: Your body stores glucose in the liver and in muscle tissue in the form of glycogen. When you require energy, either for normal functions or for physical activity, the glycogen is broken down to release glucose into the blood stream. Your pancreas tries to maintain a normal concentration of glucose in your blood by relying on two hormones ... insulin and glucagon.
When insulin is released, it causes the liver and muscle tissue to store glucose, forms fats from fatty acids and glycerol, and stimulates the liver and muscle tissue to synthesise proteins from amino acids.
When glucagon is released, it cause the liver and muscle tissue to break down glycogen and release glucose. Glucagon has the opposite effect as to Insulin but they are both required to maintain a normal blood glucose level (90 mg per 100 ml of blood) within your body.
Introducing dextrose into your diet would only become a problem if:
- an abnormal blood glucose level already existed
- you are insulin dependant
- you are insulin resistant
- your blood glucose levels were normal but you lead a sedentary lifestyle
As to the causes of diabetes:
Type 1 diabetes: Believed to be a genetic condidtion which triggers the destruction of cells which make insulin. But this is only a theory.
Type 2 diabetes: No one knows but it is primarily found in families (indicating a possible genetic trait) or in individuals who are overweight.
Gestational diabetes: Caused by a shortage of insulin during pregnancy. This usually returns to normal once the baby is born.
Also, anything which has an adverse affect on the pancrease can bring on diabetes. This includes some forms of steroids, certain medications, diseases affecting the pancrease, and high levels of niacin.
Maybe start a new thread if you need additional information as this is getting away form the original SAN V12 topic.
