At a Glance
- Different milks provide different nutrition, and can affect how filling or satisfying your coffee feels.
- Dairy and non-dairy options vary in calories, protein, and lactose.
- Choose the milk that matches your needs and how you like your coffee.
Different types of milk can change the calorie count, creaminess, and overall nutrition of your coffee. Choosing the right option for you may depend on your health goals and preferences.
Which Milk Is Healthiest to Add to Coffee?
There's no single "best" milk for everyone, but each type offers different benefits depending on your goals. Among dairy options, skim milk is lowest in calories and saturated fat, while whole milk is richer and more satisfying. Non-dairy milks vary widely. While some unsweetened varieties are low-calorie and fortified, others can be higher in fat, added sugars, or carbohydrates.
How Skim Milk Compares: Low-Calorie and High-Protein
Skim milk is essentially fat-free dairy, so it delivers protein and calcium without the extra calories and saturated fat found in whole milk. Because it lacks fat, skim milk doesn’t add creaminess, and some people find it thins out coffee. It's a solid choice if you want a leaner cup that still provides protein.
One cup of skim milk provides:
- Calories: 80
- Protein: 8 grams (g)
- Carbohydrates: 12 g
- Total fat: 0 g
- Calcium: 322 milligrams (mg), or 25% of the Daily Value (DV)
How Whole Milk Compares: Creamier and More Satisfying
The saturated fat in whole milk gives coffee a richer texture and a more satisfying flavor. The fat can also slow digestion slightly, which may help some people feel fuller, especially if they're adding more than just a splash. If you're not concerned about calories or saturated fat, whole milk can make your coffee feel creamier and more indulgent.
One cup of whole milk contains:
- Calories: 150
- Protein: 8 g
- Carbohydrates: 11.3 g
- Total Fat: 8 g
- Saturated Fat: 4.5 g
- Calcium: 300 mg, or 23% of the DV
How Non-Dairy Milks Compare: It Depends on the Type
Non-dairy milks vary more than dairy milks, not just in calories and nutrients, but also in how they're fortified. Many brands add calcium and vitamin D, sometimes in amounts higher than in dairy milk. Other brands keep the ingredient list minimal, which is why the nutrition can differ so much from carton to carton. Here's how the most common varieties compare in coffee.
Oat Milk
Oat milk is creamy and naturally sweet, which is why many people enjoy it. It tends to be higher in carbohydrates than other non-dairy options, which is something to keep in mind if you're watching your carb intake.
An 8-ounce serving of oat milk includes:
- Calories: 79
- Protein: 4 g
- Carbohydrates: 14 g
- Total Fat: 1.5 g
- Calcium: 19.2 mg, or 1.9% of the DV
Almond Milk
Almond milk is light, low in calories, and has a mild flavor that doesn't overpower coffee. It's one of the lowest-calorie options, but it’s also very low in protein. Some varieties can separate in hot coffee unless they're formulated as a barista blend.
A 1-cup serving of unsweetened almond milk contains:
- Calories: 29
- Protein: 1 g
- Carbohydrates: 1 g
- Fat: 2.5 g
- Calcium: 451 mg, or 45% of the DV
Soy Milk
Nutritionally, soy milk is the closest plant-based alternative to dairy, offering more protein than most other non-dairy milks. Its creamier texture can also make coffee feel more substantial without adding many extra calories.
If you’re considering soy milk, this is the nutrition per 1 cup (unsweetened):
- Calories: 93
- Protein: 9 g
- Carbohydrates: 3 g
- Fat: 5 g
- Calcium: 246 mg, or 19% of the DV
Does the Type of Milk Change How Coffee Makes You Feel?
The type of milk you use in your coffee can affect how you feel, especially if you’re sensitive to lactose (a natural milk sugar), added sugars, or certain fats.
Dairy milks, such as skim and whole, contain lactose, which may cause bloating or digestive discomfort for people who don’t tolerate it well. Non-dairy milks are naturally lactose-free, but sweetened versions can add more sugar than you might expect, which may lead to quicker rises and drops in blood sugar.
Milk choice can also influence how satisfying your coffee feels. Whole milk and creamier oat milks often make a drink feel more substantial, which may help curb mid-morning hunger, while lighter options like skim or almond milk keep the cup lower in calories but may not provide the same sense of fullness.
How to Choose the Best Milk for Your Coffee
When you're choosing the healthiest milk for your coffee, it helps to consider your goals.
- For lowest calories: Lighter options like skim milk or unsweetened almond milk can help keep your calorie count low.
- For highest protein: Skim, whole, and unsweetened soy milk all offer meaningful amounts of protein.
- For lactose-free: If you're sensitive to lactose, a non-dairy option, such as oat, almond, or soy, may help you avoid digestive discomfort.
The amount of milk you add to your coffee can also matter. A small splash won't change much nutritionally, but a latte-sized pour can significantly affect calories, fat, and sugar. Unsweetened non-dairy milks help keep added sugars down, while whole milk or creamier oat milks can make your drink more filling if that's something you prefer.
Drinking your coffee black is always an option if you prefer to avoid added calories altogether.
Ultimately, the healthiest choice is the one that aligns with your nutritional goals, taste preferences, and how you want your morning coffee to make you feel.
