Coffee has a moderate Glycemic Index (GI) of 50, placing it in the medium GI category. However, what’s particularly interesting is that despite this moderate GI value, coffee has a Glycemic Load (GL) of 0.

Considerations When Consuming Coffee
While plain coffee has minimal calories and no carbohydrates, it’s important to remember that additions like sugar, flavored syrups, and cream can significantly alter its nutritional profile and glycemic impact. These additions can transform a zero-GL beverage into one that substantially affects blood sugar levels.
Tips for Healthier Coffee Consumption
- Opt for black coffee or use a small amount of milk
- Choose unsweetened options or use sugar alternatives if needed
- Be mindful of coffee shop beverages, which often contain hidden sugars
- Consider cinnamon as a natural, low-GL flavor enhancer
Conclusion

As with any dietary component, moderation is key. While coffee offers potential health benefits, excessive consumption may lead to side effects like anxiety, insomnia, or digestive issues in sensitive individuals.
