Coffee, Brewed: A Detailed Glycemic Index Overview
Coffee is one of the world’s most popular beverages, consumed by millions daily. But what does coffee mean for your blood sugar levels? Let’s dive into the glycemic impact and nutritional profile of brewed coffee.
Glycemic Index and Load of Brewed Coffee
Our user-friendly app features a searchable database, meal planning tools, and personalized recommendations based on your health goals.
Glycemic Index (GI): 50 (Medium)
Glycemic Load (GL): 0
While coffee has a moderate glycemic index of 50, its glycemic load is essentially zero. This apparent contradiction occurs because coffee contains virtually no carbohydrates, meaning it won’t significantly impact blood glucose levels despite its medium GI rating.
Nutritional Profile (Per 100ml)
- Calories: 1
- Protein: 0.12g
- Fat: 0.02g
- Carbohydrates: 0g
- Fiber: 0g
- Sugar: 0g

What This Means For Blood Sugar Management
Brewed coffee, in its pure form, is essentially carbohydrate-free, making it a blood sugar-friendly beverage option. The zero glycemic load indicates that consumption of black coffee will have minimal impact on blood glucose levels.
Important Considerations
Additions Matter: While black coffee won’t spike blood sugar, additions like sugar, flavored syrups, or certain creamers can dramatically increase both the glycemic index and load of your coffee beverage.
Caffeine Effects: Some research suggests caffeine may temporarily affect insulin sensitivity in certain individuals. Those with diabetes may want to monitor their individual response to coffee consumption.
Who Can Benefit From Brewed Coffee?
- People with diabetes looking for zero-carb beverage options
- Those following low-carb or ketogenic diets
- Anyone monitoring their glycemic load intake
- Weight management seekers looking for low-calorie options
The Bottom Line
Pure brewed coffee is an excellent beverage choice for those monitoring blood sugar levels. With zero carbs and minimal calories, it won’t contribute to blood glucose spikes when consumed black. However, be mindful of what you add to your coffee, as sweeteners and creamers can transform this blood-sugar friendly drink into a high-glycemic option.
Always consult with your healthcare provider about coffee consumption if you have specific health concerns related to blood sugar management or metabolic conditions.
