5 min read

According to a study discussed on Coffee-Bike's blog, mixing coffee's polyphenols with milk's proteins might have anti-inflammatory effects. However, when considering overall health, the choice between a café au lait and a latte depends on preparation and health goals.

Quick Summary

This article analyzes the key differences between a café au lait and a latte, focusing on their ingredients, brewing methods, and nutritional profiles. The comparison highlights how the type of coffee and milk ratio influence calories, caffeine, and overall health impact, helping you make a more informed choice.

Key Points

  • Brewing method is key: A café au lait uses brewed coffee, while a latte is based on espresso, which affects acidity and overall caffeine levels.

  • Calories depend on milk: Lattes typically have more calories due to a higher volume of milk, but both can be made healthier by choosing lower-fat milk and skipping sugary additions.

  • Caffeine levels are complex: Total caffeine is influenced by the type and amount of coffee used, with a café au lait potentially containing a higher overall dose from brewed coffee, even though espresso is more concentrated.

  • Stomach sensitivity: Those with sensitive stomachs may prefer a latte, as espresso's brewing process reduces acidity compared to standard brewed coffee.

  • Nutritional boost: Lattes offer more calcium and protein due to their higher milk content, making them a better choice for post-workout recovery or boosting nutrient intake.

  • Making a healthier choice: Regardless of the drink, avoiding excessive sugar and choosing lower-fat milk options are the most effective ways to improve the health profile of both beverages.

Understanding the Fundamentals: Café au Lait vs. Latte

While both a café au lait and a latte are milk-based coffee beverages, their fundamental differences in preparation and ingredients are what truly set them apart from a nutritional standpoint. A traditional café au lait is made with a 50/50 ratio of brewed coffee (often from a French press or drip machine) and steamed milk. In contrast, a latte is constructed with a shot of espresso and a larger portion of steamed milk, topped with a thin layer of microfoam. This distinction in base and ratio means that the final nutritional profile can vary significantly.

Brewing Method Matters

The choice of coffee base is a major factor in the health comparison. A latte's espresso base is brewed under high pressure for a very short time. This process removes much of the chlorogenic acid (CGA), which can be irritating to some stomachs, and results in a lower caffeine content ounce-for-ounce compared to regular drip coffee. A café au lait, using drip or French press coffee, has a longer brewing time, extracting more of these compounds. Therefore, for someone with a sensitive stomach, the espresso base of a latte might be a gentler option.

The Milk and Calorie Factor

The proportion of milk is the most significant contributor to the calorie and nutrient difference between these two drinks. A standard café au lait uses a 1:1 ratio of coffee to steamed milk, while a latte typically contains a higher proportion of milk. A latte with whole milk can have over 150 calories, whereas a café au lait might have fewer calories depending on the milk-to-coffee ratio.

  • Higher milk volume in a latte: This means more calories and fat if using whole milk, but also more calcium, protein, and other nutrients.
  • Lower milk volume in a café au lait: This generally results in a lower calorie count and a stronger coffee flavor, assuming no extra sweeteners are added.

Ultimately, the healthiest version of either drink depends on the type of milk chosen. Opting for skim or a plant-based milk like almond milk can dramatically reduce the calorie count of a latte, bringing it closer to the café au lait's typical range.

Comparison Table: Café au Lait vs. Latte

Feature Café au Lait Latte
Coffee Base Drip or French press coffee Espresso shot(s)
Milk Ratio Typically 50% coffee, 50% steamed milk Higher milk proportion (e.g., 2:1 milk to espresso)
Caffeine Content Can be higher overall, depending on brew strength Ounce-for-ounce higher in espresso, but diluted by milk
Foam Usually none or very little Thin layer of microfoam on top
Flavor Profile Stronger coffee flavor due to higher coffee ratio Milder, creamier flavor due to higher milk content
Calorie Count (approx) Lower, depending on milk choice (e.g., 85 kcal with milk) Higher, depending on milk choice (e.g., 150 kcal with whole milk)
Acidity Potentially more acidic depending on brew method Lower acidity due to espresso and buffering from milk

The Role of Caffeine

The caffeine content is another area where these two drinks differ, though the outcome isn't always what you'd expect. While an espresso shot has a high caffeine concentration, the larger volume of milk in a latte effectively dilutes it. A café au lait made with a strong, dark roast filter coffee can have a surprisingly high total caffeine content, sometimes in the range of 80 to 120 mg. The milk in both beverages also affects the rate of caffeine absorption, providing a more gradual, sustained energy boost compared to black coffee.

Which is Healthier for You?

The answer to which is healthier is nuanced and dependent on individual needs. For those watching calorie and fat intake, a café au lait made with low-fat or skim milk is often the better choice due to its lower milk ratio. However, if stomach sensitivity is a concern, the lower acidity of an espresso-based latte could be more beneficial. Additionally, the extra milk in a latte provides more protein and calcium, which can be advantageous for post-workout recovery or for those needing to increase their nutrient intake. For maximum health benefits, the key is to avoid adding excessive sugar, syrups, or whipped cream to either beverage.

Conclusion: Making the Best Choice for Your Health

In conclusion, neither a café au lait nor a latte is inherently superior in health. The healthier option is the one that best fits your dietary goals and personal preferences. The café au lait generally has fewer calories and a stronger coffee taste, making it ideal for those seeking a straightforward, lower-calorie coffee and milk mix. The latte, with its smoother flavor profile and higher milk content, offers more calcium and protein but comes with a higher calorie count. By being mindful of the brewing method and, most importantly, the type of milk and sweeteners used, you can make either drink a healthy part of your daily routine. Understanding the subtle differences empowers you to tailor your coffee order precisely to your wellness needs, whether at home or at your favorite café.
