Buttermilk, a tangy and versatile dairy product, is a popular ingredient in various recipes, from fluffy biscuits to savory fried chicken. However, if you're following a low-carb or ketogenic diet, you might be wondering whether buttermilk is a suitable choice. This article delves into the nutritional profile of buttermilk, its impact on ketosis, and potential low-carb alternatives.
What is Buttermilk?
Buttermilk is a dairy product traditionally obtained as a byproduct of butter-making. Today, most commercially available buttermilk is cultured buttermilk, made by adding lactic acid bacteria to milk. These bacteria ferment the milk, converting lactose into lactic acid, which gives buttermilk its characteristic tangy flavor and slightly thickened texture.
Nutritional Value of Buttermilk
A one-cup serving (240g) of buttermilk contains approximately:
- Calories: 98
- Protein: 8 grams
- Carbohydrates: 12 grams
- Fat: 2.2 grams
Buttermilk also provides essential nutrients like calcium, vitamin B12, and potassium.
Buttermilk and Ketosis: Is it a Good Fit?
The ketogenic diet is a high-fat, very low-carb diet that forces the body to switch from burning glucose (sugar) to burning fat for fuel. This metabolic state, called ketosis, is achieved by drastically reducing carbohydrate intake, typically to less than 50 grams per day.

Given that one cup of buttermilk contains around 12 grams of carbs, it may not be the most keto-friendly choice, especially if you're strictly limiting your carb intake. Consuming even a small serving of buttermilk could potentially kick you out of ketosis, depending on your individual carb tolerance and the other foods you consume throughout the day.
It's important to consider net carbs, which are calculated by subtracting the fiber content from the total carbs. Unfortunately, buttermilk lacks significant amounts of fiber, so the net carb count is nearly the same as the total carb count.
Can Buttermilk Fit into a Low-Carb Diet?
While buttermilk may not be ideal for a strict ketogenic diet, it can be incorporated in moderation into a more general low-carb diet. If you're following a less restrictive low-carb approach, you might be able to include small amounts of buttermilk in your recipes while staying within your daily carb limits. However, it's crucial to track your carb intake carefully and adjust your other food choices accordingly.
Keto-Friendly Buttermilk Substitutes
If you're looking for a low-carb alternative to buttermilk, several options can provide a similar flavor and texture in your recipes:
- Unsweetened Almond Milk: Almond milk is a popular dairy-free alternative that's very low in carbs. You can add a tablespoon of lemon juice or vinegar to a cup of almond milk to mimic the tanginess of buttermilk.
- Coconut Milk: Unsweetened coconut milk is another low-carb option that can be used in place of buttermilk. It has a higher fat content than almond milk, which can be beneficial on a keto diet.
- Yogurt: Plain, unsweetened yogurt, especially Greek yogurt, is a good substitute for buttermilk. It has a similar tangy flavor and creamy texture. You may need to thin it out with a little water or milk to match the consistency of buttermilk.
- Sour Cream: Sour cream can be thinned with water or milk to achieve a buttermilk-like consistency. It adds a rich, tangy flavor to recipes.
Using Buttermilk in Baking: Considerations
Buttermilk is a popular ingredient in baking because its acidity helps to tenderize gluten in flour, resulting in softer and more tender baked goods. It also reacts with baking soda to create a leavening effect, contributing to the rise of cakes, pancakes, and biscuits.

If you're using a buttermilk substitute in a baking recipe, keep in mind that the taste and texture of the final product may be slightly different. You may need to adjust the amount of baking soda or other leavening agents to achieve the desired results.
Health Benefits of Buttermilk
Despite its relatively high carb content, buttermilk offers several health benefits:
- Protein: Buttermilk is a good source of protein, which is essential for building and repairing tissues in the body. One cup of buttermilk provides 8 grams of protein.
- Calcium: Buttermilk is rich in calcium, a mineral that's crucial for strong bones and teeth.
- Vitamins and Minerals: Buttermilk contains vitamin B12, potassium, and other essential nutrients.
Buttermilk vs. Yogurt: A Nutritional Comparison
Both buttermilk and yogurt are fermented dairy products with distinct nutritional profiles. Here's a comparison based on 100-gram servings of low-fat buttermilk and nonfat Greek yogurt:
| Nutrient | Buttermilk (Low-Fat) | Yogurt (Greek, Nonfat) |
|---|---|---|
| Calories | 40 | 59 |
| Protein | 3.31g | 10.19g |
| Fat | 0.88g | 0.39g |
| Carbohydrates | 4.79g | 3.6g |
| Calcium | Similar amounts | Similar amounts |
| Glycemic Index | 31 | 19 |
Key takeaways:
- Yogurt is richer in protein than buttermilk.
- Buttermilk has slightly more fat and carbohydrates than nonfat yogurt.
- Both are low-glycemic index foods.
- Buttermilk is richer in some vitamins (A, D, E, K, C, B1), while yogurt is richer in others (B2, B3, B5, B6, B9, B12).
- Both are good sources of calcium.
