![]() ![]() Rather than simply testing the glucose response to 50 g of carbohydrates, the Glucose Score tests the two-hour glucose response to a fixed amount (1000 kJ or 239 calories) of any food.Įxcitingly, the Glucose Score allows us to compare the glucose response to any food, not just high-carbohydrate foods! Glucose Score Data If you are someone with T2D or severe metabolic syndrome, it’s recommended to prioritise Low-GI foods. High-Glycemic Index foods – greater than 100.Low-Glycemic Index foods – less than 55.Conversely, foods with a glycemic index greater than 70 are considered ‘high’, and those in the middle are considered ‘moderate’. Generally, foods with a GI that’s less than 55 are considered ‘low’-Glycemic Index foods. Unfortunately, one of the limitations of the GI data is that it is usually only tested on high-carb foods and thus excludes higher fat and higher protein foods. The ratio between the two responses is the Glycemic Index. The same ten subjects are later fed a high-glucose food (e.g., white bread), and the area under the curve glucose response is calculated. The area under the two-hour blood glucose response for the food is then calculated. The GI is calculated by feeding ten metabolically-healthy subjects a portion of food containing 50 grams of carbohydrates and measuring their blood glucose over the next two hours. The GI has since become one of the most widely used tools for people with diabetes trying to manage their blood sugar levels. Jenkins and colleagues at the University of Toronto in the early 1980s. The Glycemic Index was developed by Dr David J. ![]() Thus, Glycemic Load is a more accurate indicator of a food’s effect on blood sugar levels than the Glycemic Index alone because it accounts for the quantity and quality of carbohydrates in a food. The formula for calculating Glycemic Load is: Glycemic Load (GL) considers the quantity of carbohydrates in a food and how quickly the body metabolises them. Thus, it will have a lower Glycemic Load. While you might be able to eat a few bowls of cereal, it’s hard to eat a lot of spinach. While chronically elevated blood glucose leads to many complications over the long term, it’s the crash in glucose that you be aware of to avoid excessive hunger and maintain consistent energy levels.Īlthough a food may have a high GI, it won’t raise your glucose much if you only eat a little bit of it. This leads to increased hunger, eating sooner, and overeating less-optimal foods at the next meal (i.e., reactive hypoglycemia). The more your glucose rises, the more likely it is to come crashing back down. In a world awash with diabetes and insulin resistance, optimising your blood glucose is a big deal! Elevated glucose is generally a sign of poor metabolic health and insulin resistance, often stemming from obesity.
