Understanding Glycemic Index
Glycemic index (GI) measures how quickly foods containing carbohydrates raise blood glucose levels. It provides valuable information for managing blood sugar, especially for people with diabetes or those aiming to optimize their diet.
Fundamentals of Glycemic Index
The glycemic index ranks foods on a scale from 0 to 100 based on how they affect blood sugar levels. Foods with a high GI (70 or above) cause rapid spikes in blood glucose. Medium GI foods (56-69) lead to moderate increases. Low GI foods (55 or below) result in slower, more gradual rises.
Glycemic load (GL) combines the GI with the amount of carbohydrates in a serving. This gives a more accurate picture of a food’s impact on blood sugar. To calculate GL, multiply the GI by the grams of carbs per serving and divide by 100.
Glycemic Index of Pineapple
Fresh pineapple has a medium glycemic index, typically ranging from 51 to 66. The exact GI can vary depending on ripeness and preparation method. A 1-cup serving (165g) of diced pineapple contains about 13g of carbohydrates.
Using these values, we can calculate the glycemic load:
GL = (GI x carbs per serving) / 100
GL = (66 x 13) / 100 ≈ 8.6
This moderate GL suggests that pineapple can be part of a balanced diet, even for those monitoring their blood sugar. However, portion control remains important.
