What is the GI value for complex carbohydrates?

Explanation:
The concept being tested is how foods are classified by glycemic index (GI) based on how quickly they raise blood glucose. Complex carbohydrates are made up of longer starch chains and often come with fiber, which slows digestion. Because digestion is slower, glucose enters the bloodstream more gradually, producing a smaller, slower rise in blood sugar. That’s why complex carbohydrates are generally categorized as low GI (typically 55 or less). It’s helpful to note that GI can vary with preparation and processing—more processed forms can raise the GI—but in their natural or minimally processed state, complex carbs like whole grains, legumes, and vegetables tend to have a low GI.
