Briefly explain the glycemic index and one common misconception about it.

## Glycemic Index (GI) The glycemic index is a ranking system (0-100) that measures how quickly a carbohydrate-containing food raises blood glucose levels compared to pure glucose. Low GI foods (≤55) cause a slower, gradual rise, while high GI foods (≥70) cause a rapid spike. ## Common Misconception **"High GI foods are always unhealthy and should be avoided"** This oversimplifies nutrition. The GI doesn't account for: - **Portion size** - watermelon has a high GI but low carbs per serving (low glycemic load) - **Nutrient density** - some high GI foods like potatoes and whole grain bread are nutritious - **Food combinations** - adding protein, fat, or fiber to a high GI food slows glucose absorption Context matters more than GI alone. A balanced approach considering overall diet quality is more important than strictly avoiding high GI foods.
