Why is there protein in my coffee?

According to a 2021 study in 'Cell Reports,' older women who ate more protein in the morning had increased muscle mass compared to those who ate it later. This finding highlights a key driver behind the popular 'proffee' trend, which incorporates protein into your morning brew for enhanced nutritional benefits.

Quick Summary

Protein in coffee is a popular trend known as 'proffee,' where protein powder or shakes are added to coffee for enhanced nutrition. This combination offers benefits like increased satiety and sustained energy, though improper mixing can lead to a gritty texture. It serves as a convenient way to boost daily protein intake, but is not a replacement for a balanced diet.

Key Points

• Natural Protein is Minimal: Coffee beans contain some protein, but roasting and brewing leave only a negligible amount in your cup; added protein is almost always intentional.

• Clumping is Caused by Heat: Adding protein powder directly to very hot coffee can cause clumping; mixing with a cool liquid first or using a blender prevents this.

• Benefits Include Satiety and Sustained Energy: Combining protein and caffeine can enhance feelings of fullness and provide a more gradual, sustained energy boost, preventing a mid-morning crash.

• Check Your Powder's Ingredients: Some protein powders contain high sugar or artificial additives. Opt for a high-quality product with a simple ingredient list to avoid unwanted extras.

• It's a Supplement, Not a Meal: While a convenient nutritional boost, 'proffee' should not replace a balanced breakfast rich in whole foods, vitamins, and minerals.

Is There Natural Protein in Coffee?

While coffee is not a significant source of protein on its own, it does contain trace amounts naturally derived from the bean itself. Green coffee beans contain approximately 8.5% to 12% crude protein. However, the roasting and brewing processes significantly alter this composition, leaving only minimal protein in a standard cup of black coffee. A regular 6-ounce cup of black coffee contains a negligible amount, roughly 0.21 grams. The protein that people refer to in their coffee is almost always an added ingredient, such as protein powder, milk, or a pre-made protein shake.

The Rise of the 'Proffee' Trend

The term "proffee"—a portmanteau of protein and coffee—has surged in popularity on social media platforms like TikTok, turning the simple act of adding protein powder to coffee into a global trend. This movement is fueled by the pursuit of convenient and efficient nutrition. People are increasingly looking for ways to maximize the benefits of their daily routines. Mixing protein powder into a morning coffee provides a two-in-one solution for both a caffeine boost and a protein hit, especially for those with busy schedules or who aren't traditional breakfast eaters.

Potential Benefits of Adding Protein

Adding a scoop of protein powder to your coffee can transform it from a simple energy booster into a more functional beverage. The combination creates several synergistic effects that impact your body and mind.

• Enhanced Satiety and Weight Management: Protein is known to increase feelings of fullness, helping to curb hunger throughout the morning. This can lead to a reduction in overall daily calorie intake and better weight management.
• Sustained Energy: When paired with protein, the caffeine in coffee is absorbed more slowly by the body. This helps prevent the rapid energy spike and subsequent crash often associated with drinking black coffee on an empty stomach, leading to more sustained alertness.
• Muscle Growth and Recovery: For athletes and active individuals, adding protein to a pre- or post-workout coffee can support muscle repair and growth. The caffeine can boost exercise performance, while the protein supplies the essential amino acids needed for recovery.
• Metabolic Boost: Both coffee and protein have thermogenic effects, meaning they cause your body to burn more calories during digestion. The combination can enhance your metabolism-boosting efforts.
• Convenience: For people who struggle to consume enough protein or tend to skip breakfast, a protein-infused coffee is a quick and simple way to get 15–25 grams of high-quality protein without extra meal prep.

Comparison of Common Protein Powder Types

Choosing the right protein powder is crucial for achieving your desired taste, texture, and nutritional profile. Below is a comparison of some popular types used in coffee.

Protein Type	Characteristics	Best for	Notes
Whey Protein	Dairy-based, mixes relatively smoothly.	Creamy, milky coffee texture; muscle recovery.	Can clump in very hot liquids. Best mixed with cold liquid first.
Plant-Based	Includes pea, hemp, and soy protein.	Vegan and dairy-free options; muscle recovery.	Can have an earthier flavor and slightly grittier texture.
Collagen Protein	Dissolves easily in hot liquid; neutral flavor.	Joint and skin health; people who dislike altered taste.	Not a complete protein source; lacks essential amino acids.
Casein Protein	Dairy-based, thicker consistency when mixed.	Slow-release protein for sustained satiety.	Prone to clumping in hot coffee if not mixed correctly.

How to Avoid Clumping and Grittiness

One of the most common complaints about mixing protein powder into coffee is the resulting clumpy or gritty texture. Protein coagulation occurs when it is exposed to high heat and the acidic nature of coffee. To achieve a smooth, creamy finish, follow these preparation steps:

1. Start with a cooler base: Allow your hot coffee to cool slightly before adding the protein powder. Alternatively, use cold brew or chilled coffee for an iced version, which eliminates the clumping risk entirely.
2. Use a small amount of liquid: Mix the protein powder with a small splash of cold milk (dairy or plant-based) or water first to create a smooth paste. This prevents the powder from clumping upon contact with hot liquid.
3. Blend, don't just stir: Use a blender, immersion blender, or a handheld frother to thoroughly combine the ingredients. This creates a smooth, frothy texture similar to a latte.
4. Add slowly: If using a blender, add the hot coffee gradually to the protein mixture while blending to temper the temperature and maintain a smooth consistency. For iced coffee, simply add all ingredients and blend.

Potential Drawbacks and Health Considerations

While protein coffee offers benefits, there are potential drawbacks to consider, especially for certain individuals.

• Digestive Issues: Some people, particularly those with lactose intolerance, may experience digestive discomfort like bloating or gas from whey or casein proteins. Plant-based options may be better in this case, but can still cause issues for sensitive individuals.
• Overconsumption: Adding 25-30 grams of protein to your morning coffee can lead to an excessive protein intake if you already consume a high-protein diet. For most healthy adults, this isn't an issue, but those with pre-existing kidney conditions should monitor their intake and consult a doctor.
• Caffeine Overload: The increased energy from the combination might lead to overconsumption of coffee, which can cause anxiety, jitters, or sleep disturbances in caffeine-sensitive individuals.
• Ingredient Quality: Not all protein powders are created equal. Some may contain unnecessary fillers, artificial sweeteners, or high amounts of sugar. Always choose a high-quality product with a clean ingredient list.

Conclusion: A Convenient Boost, Not a Meal Replacement

Ultimately, the protein in your coffee is there by design—a convenient, intentional addition to boost your morning nutrition. For many, this practice offers an effective way to improve satiety, sustain energy levels, and support fitness goals. However, it's essential to understand that while it offers nutritional value, protein coffee should not replace a balanced meal. It serves as a tool to supplement your diet, not to be a primary source of nutrients. By following proper mixing techniques and being mindful of your body's individual needs, you can enjoy a smooth, creamy, and nutritionally enhanced cup of 'proffee' as a beneficial part of your daily routine.
