Glycemic Index Calculation: Glycemic Index ranks carbohydrate foods on a scale from 0 to 100 in relation to how they affect your blood sugar levels. The lower the number the smaller the fluctuations are in your blood sugar and insulin levels. Foods with a GI of 70 or higher are considered "high" foods, foods with a GI of 55 to 70 are "moderate," and foods with a GI 55 or below are considered "low." Facts About Glycemic Index: Glycemic Index does not take food serving size or proportion into consideration. When foods are measured, or indexed, scientists take the index from the amount of food that would have 50 grams of carbohydrate. This is where foods such as carrots and watermelon come in. Carrots are considered a "high" food, yet an individual would have to eat a whopping pound and a half of them to match the amount of food that puts carrots in the "high" category.
