With the number of new diabetes cases constantly on the rise, the term “glycemic” inevitably finds itself staking a greater claim in the English language. Interestingly enough, there seems to be a lot of confusion surrounding its context. For the record, the glycemic index of a particular food refers to how rapidly the carbohydrates raise blood sugar levels within the body.
High glycemic foods are broken down very quickly. This can result in an insulin spike that can make it very difficult to properly utilize insulin, lose weight and keep energized after meals and throughout the day. Diets that consistently lean towards high-glycemic foods are routinely linked to the development of diabetes, as they decrease the body’s sensitivity to insulin.
Low glycemic foods, on the other hand, serve as a much more healthy way to go about eating. Because unlike high glycemic foods which are broken down very quickly, low glycemic foods are utilized in a much more gradual manner. This results in a slow, sustained rise in blood sugar and insulin levels. Under these circumstances, the body is much more capable of losing weight, managing hunger and keeping well-fueled throughout the long day. Low glycemic foods are of considerable concern to individuals living with both Type 1 and 2 diabetes, as they’ve been shown to improve blood lipid and glucose levels.
The glycemic index is a tool used to measure (from 1 to 100) how quickly carbohydrates from the diet can raise blood sugar levels. Anyone concerned with managing their blood sugar levels should make a conscious effort to consume foods with lower glycemic ratings. If you’ve never had your glucose tested, your family physician can initiate a simple test that will help you in deciding where you stand, from a blood lipid and glucose perspective.
