Coffee, Latte: A Creamy Comfort with Moderate Glycemic Impact
A warm cup of latte is a beloved morning ritual for many coffee enthusiasts. But how does this creamy espresso-based beverage fit into a glycemic-conscious lifestyle? Let’s explore the glycemic profile and nutritional breakdown of this popular coffee drink.
What is a Latte?
Our user-friendly app features a searchable database, meal planning tools, and personalized recommendations based on your health goals.
A latte consists of espresso topped with steamed milk and a small layer of milk foam. The higher ratio of milk to coffee gives it a milder, creamier taste compared to other espresso-based beverages.
Glycemic Index and Glycemic Load
The glycemic index (GI) of a latte is 68, which places it in the moderate to high GI range. However, the glycemic load (GL) tells a more complete story.
With a glycemic load of just 2.96, latte has a low impact on blood sugar levels when consumed in standard servings. This low GL is due to the relatively small amount of carbohydrates in a 100g serving.
Nutritional Breakdown
Per 100g serving, a latte provides:
- Calories: 43
- Protein: 2.81g
- Fat: 1.61g
- Carbohydrate: 4.35g
- Fiber: 0g
- Sugar: 4.06g
- Net Carbs: 4.35g
Understanding the Glycemic Impact
While the GI of 68 might seem concerning for those monitoring blood sugar, the low carbohydrate content results in a minimal glycemic impact when consumed in normal portions. The 4.35g of carbohydrates mainly come from the lactose in milk, which is naturally occurring sugar.
Health Considerations
A latte offers some nutritional benefits worth noting:
- The 2.81g of protein contributes to your daily protein needs
- The calcium from milk supports bone health
- The modest fat content (1.61g) helps with the absorption of fat-soluble vitamins
Making Lattes More Glycemic-Friendly
If you’re concerned about the glycemic impact, consider these modifications:
- Request unsweetened latte (avoid added syrups or sugar)
- Choose non-dairy alternatives like almond or coconut milk which typically contain fewer carbs
- Opt for a smaller serving size
- Consider a sprinkle of cinnamon instead of sugar, which may help regulate blood sugar
Bottom Line
Despite its moderate glycemic index of 68, a plain latte has a low glycemic load of 2.96, making it a reasonable choice for most people monitoring blood sugar levels. The key is avoiding added sugars and syrups that would significantly increase both GL and GI.
As with any food or beverage, moderation is important, especially if you have diabetes or other conditions requiring careful blood sugar management. For most individuals, an occasional unsweetened latte can fit well within a balanced, glycemic-conscious eating pattern.
