Buttermilk On Keto: Friend Or Foe?

Buttermilk is a popular choice for bakers, but is it allowed on the keto diet? The keto diet is famous for its low-carb and high-fat content, and generally, a 1-cup serving of buttermilk has 12-13 grams of net carbohydrates, which is a lot for the keto diet. However, there are ways to include buttermilk in your keto recipes, such as using small amounts in baking. So, is buttermilk allowed in keto? The answer is, it depends.

Buttermilk is high in carbs

Buttermilk is a fermented dairy product that is a popular choice for bakers. It is made by introducing bacteria to low-fat cow's milk, and this mixture is then heated. However, buttermilk contains a high amount of carbohydrates, which can be a problem for those on a keto diet.

A typical serving of buttermilk contains 11 to 13 grams of carbohydrates, primarily from sugars. This is a significant amount considering that those on a strict keto diet usually limit their daily net carbs to 20-50 grams. A full cup of buttermilk could quickly reach this limit, potentially disrupting ketosis.

The high carb content in buttermilk is due to the milk sugar lactose, which is the primary sugar in milk. Additionally, commercial brands of buttermilk often contain added sugars, preservatives, artificial colours, and flavours, making them even higher in carbs.

While buttermilk is not keto-friendly as a drink, it can still be incorporated into keto baking in small amounts. A 1-ounce serving of buttermilk contains only around 1.5 grams of net carbs, which can be manageable within a keto diet. It is important to practice portion control and carefully plan your carb intake when including buttermilk in your keto diet.

If you are looking for alternatives to buttermilk that are more keto-friendly, there are several options available. You can create your own keto buttermilk by using heavy cream and churning it at high speeds until it separates into butter and buttermilk. You can also try dairy-free alternatives such as unsweetened almond or coconut milk mixed with lemon juice or apple cider vinegar to achieve a similar tangy flavour.

Buttermilk is made from cow's milk

Today, most buttermilk is cultured buttermilk, which is not a byproduct of butter-making. Cultured buttermilk is made by adding active bacteria cultures to whole or low-fat milk. The mixture is then heated and allowed to ferment for about 12 hours. This fermentation process thickens the buttermilk and adds compounds like lactic acid and diacetyl, which give buttermilk its distinctive tangy taste and buttery flavour.

Buttermilk is used in a variety of ways, both fresh and cooked. It is a popular ingredient in baked goods, marinades, and dressings, and it is well-known for its ability to tenderise meat and create fluffy textures in baked goods.

Buttermilk has a high sugar content

Buttermilk is a fermented dairy product that is commonly used in baking. It is made by introducing bacteria to low-fat cow's milk and heating the mixture. This process gives buttermilk its distinctive tangy taste and thicker consistency compared to regular milk.

One cup (245-254 grams) of buttermilk contains 12-13 grams of carbohydrates, which is a significant amount for individuals following a keto diet. The recommended daily carbohydrate intake on a keto diet is between 20-50 grams, so a single serving of buttermilk can quickly deplete an individual's daily carbohydrate allowance.

Buttermilk's high sugar content is due to the presence of lactose, the primary sugar found in milk. The bacteria added to the milk ferment the lactose, resulting in the slightly sour taste characteristic of buttermilk.

The sugar in buttermilk can cause a rapid increase in blood sugar levels, leading to an insulin spike. Insulin is responsible for regulating blood glucose levels, and disruptions in insulin levels can have serious health consequences.

Additionally, commercial brands of buttermilk often contain added sugars, preservatives, artificial colours, and flavours, making them even higher in sugar content and potentially more harmful for individuals following a keto diet.

Therefore, due to its high sugar content, buttermilk is generally not considered suitable for a keto diet, especially in larger quantities. However, small amounts of buttermilk may be used in keto baking, as the carbohydrates are dispersed, reducing the amount per serving.

Buttermilk contains no fibre

Buttermilk is a fermented dairy product that is often used in baking. It is made by introducing bacteria to low-fat cow's milk and heating the mixture.

Since the keto diet is mainly focused on fat consumption, it is crucial to include fibre in your diet. Buttermilk, however, does not contain any significant quantity of fibre, and therefore, it will not help your diet in any way.

If you are on a keto diet and still want to enjoy the taste of buttermilk, you can opt for fortified almond milk, unsweetened coconut milk, or plain yoghurt. These options will not only satisfy your taste buds but also keep your calories in check.

Buttermilk can be substituted with almond milk

Buttermilk is not keto-friendly, as it contains 12-13 grams of net carbs per 1-cup serving (8 oz or 240 ml). This is a significant amount of carbs for anyone on a keto diet, which typically restricts net carbs to 20-50 grams per day.

However, if you are craving buttermilk or a dish that contains it, there are ways to include it in your keto diet. Firstly, you can use a very small amount for baking, as this will disperse the carbs. A 1 oz (28 g) serving of buttermilk will only cost you 1.5 g of net carbs. Secondly, you can make your own keto-friendly buttermilk by using lower-carb alternatives such as heavy whipping cream, yogurt, or almond milk.

Almond milk is an excellent substitute for buttermilk, especially in cake recipes. It won't be as thick as buttermilk, but you can replicate the flavour by adding a little lemon juice or a splash of vinegar. These ingredients add the acidity that buttermilk typically provides, and they help to curdle the almond milk, giving it a similar texture to buttermilk.

Ingredients:

• Unsweetened almond milk
• Lemon juice or vinegar

Directions:

• Add one tablespoon of lemon juice or vinegar to a measuring cup.
• Pour in unsweetened almond milk until the measuring cup reaches the 1-cup (240 ml) line.
• Stir the mixture.
• Let it stand for about 5-10 minutes or until thickened.

And there you have it! A keto-friendly buttermilk substitute that you can use in your favourite recipes.
