Step-by-step explanation:
A food is considered to be a high glycemic index carbohydrate when it has a glycemic index (GI) score of 70 or above.
The GI is a measure of how quickly a carbohydrate raises blood sugar levels after consumption compared to pure glucose. High GI foods are rapidly digested and absorbed, causing a rapid spike in blood sugar levels.
Examples of high GI carbohydrates include white bread, white rice, and potatoes.
