Buttermilk vs Milk: Difference in Its Constituents

Milk is a natural product that comes from a mammal. Humans consume milk that comes from different mammals but I am considering cow’s milk here. Once a cow is milked, it goes through the process of pasteurization to make it drinkable. 

Traditionally, buttermilk is the leftover liquid after churning the cream and taking out the butter from it. These days it is made by combining the whole milk with cultures. It is thicker and tangy compared to the traditional or homemade buttermilk. 

How Different Is Buttermilk vs Milk Taste?

Milk contains lactose, which gives it a mild sweet taste. This sweetness makes milk a delicious beverage which can be drunk straight. It has a silky and smooth texture.

Buttermilk also has the same texture. However, its taste is completely opposite to milk. It has sourness because of the cultures in it. It is full of many good bacteria.

Buttermilk and milk have almost the same amount of carbs. Since, there is no difference in their carbs, you can replace one with the other. 

Which Contains More Fat: Buttermilk or Milk?

Whole milk has more fat content compared to buttermilk. During the making of buttermilk, most of the fast goes into butter and the leftover product has a lower fat content. Thus, buttermilk a low fat dairy product. 

For people following a diet to shed weight, buttermilk is a better choice. However, if you are preparing a recipe that needs richness, milk is better suited.

Calcium in Buttermilk vs Milk: Which Is a Better Source?

Calcium is an essential for our body for several reasons. It helps in strengthening bones and teeth and is also needed for for muscle and nerve function.

Some people take calcium supplements but diet is the best way to get the required amount. 

Dairy products are an excellent source of calcium. Compared to buttermilk, milk contains more calcium although this difference is not much. 

Buttermilk vs Milk Nutrition: What to Have for More Protein?

Our body breaks down protein into amino acids. These amino acids are helpful to repair and build tissues and muscles. They are also required to create enzymes and hormones. 

Dairy products provide you with a lot of protein and all essential amino acids. Buttermilk and milk both have the same amount of protein and thus are excellent additions to diet for protein intake. 

Best Time to Grab A Cup of Buttermilk vs Milk

Both these dairy products can go very well with your breakfast choices. You can gulp them down straight for a nutritious start of the day.

Buttermilk is a good choice for a hot summer day whereas warm milk is better for a cold day. 

You can have buttermilk in the afternoon to beat the heat. On the other hand, milk helps you sleep better. You can thus add it to your night routine. 

Buttermilk vs Milk: How Do They Impact the Ecosystem?

Growing demand for milk and its products completely changed dairy production. It is not limited to a traditional family dairy, but an industry now. This is creating a lot of pressure on natural resources. 

Dairy has 3 times more carbon footprint compared to plant based milks. This proves that milk and buttermilk are not environmentally-friendly choices. 

Which Can Be Categorized as Vegan: Buttermilk or Milk?

Neither buttermilk or milk can be part of a vegan diet. The whole idea of veganism is avoiding animal based products including dairy, meat, poultry. etc.  

There can be multiple reasons that people follow veganism. They might be lactose intolerance, environment consciousness, etc. 

Why Use Buttermilk Instead of Milk for Strong Teeth?

Many people ignore their oral health but actually it is crucial for your general well being. Calcium, vitamin D and protein are required for strong teeth. Most dairy products contain a good amount of calcium and protein and they are fortified with vitamin D.

Both milk and buttermilk are good choices for your teeth, though buttermilk will be a better one. The good bacteria or probiotics help balance out 

Buttermilk vs Milk: Better Choice for Bones 

A well balanced diet holds the key to your bone health. Your diet must contain a recommended amount of calcium, protein and vitamin D. 

You get all these nutrients through milk and buttermilk. Both these beverages are helpful to build, repair and strengthen your bones. However, milk has more calcium so it can be slightly better than buttermilk.

Buttermilk is easy to digest compared to milk. Buttermilk contains good bacteria which helps to regulate the gut function. 

It is a fermented drink which is a better choice for a healthy tummy, compared to milk. Fermented drinks are also considered helpful to boost immunity. In case you have a milk allergy then better to avoid both these dairy products. 

Buttermilk vs Milk: Which Can Be Used in Many Different Ways?

Apart from sipping them straight, both these drinks can be used in many different ways.

Milk is good for coffee, tea, shakes and smoothies. It is a perfect choice for cereals and oatmeal. On the other hand, buttermilk is an excellent choice for baking. 

Many people ask me “Why use buttermilk instead of milk in baking?” Actually, acidity in buttermilk breaks the gluten more than milk. This makes your cake light and fluffy. 

I also recommend adding buttermilk in  pancakes to get a softer texture. 

Buttermilk and milk are thus both nutritionally rich dairy products. Choose the product that suits your nutritional requirements and preferences. 

For example, if you want something richer, milk is better but if you want something easier on the stomach, choose buttermilk.
