What Is Buttermilk
Many people wonder, “what is buttermilk?” Buttermilk is a dairy liquid with a distinct tangy flavor. It comes in two main forms: traditional and cultured. Understanding the differences between these types helps clarify its uses and origins.
Traditional Buttermilk
Traditional buttermilk is a historical byproduct of making butter. Before refrigeration, milk would naturally sour. Farmers would skim this soured cream and churn it into butter. The liquid left behind after the butter formed was traditional buttermilk. This liquid contained natural lactic acid bacteria. It could be sweet or sour, depending on whether fresh or soured cream was used to start. Farmers and enslaved people historically consumed this liquid. They also used it in baking, especially after baking soda became common in the 1800s.
When butter churning day arrived, the liquid separating from the solid butter was traditional buttermilk. This process explains why traditional buttermilk was naturally “cultured.” It came from the fermentation of cream before churning. This churn buttermilk is the watery end-product of butter making. It is not high in fat, despite its name.
Here are some characteristics of traditional buttermilk:
Characteristic | Sweet Cream Buttermilk | Sour Cream Buttermilk |
|---|---|---|
Source | Churning fresh, unfermented sweet cream | Churning naturally soured or deliberately fermented cream |
Flavor | Mild, slightly sweet, less tangy | Pronounced tanginess, slight thickness |
Fat Content | Low (0.5% to 2%) | Low (0.5% to 2%) |
Protein Content | Substantial (around 3-4 grams per cup) | Substantial (around 3-4 grams per cup) |
Micronutrients | Riboflavin (B2), B12, calcium, phosphorus | Riboflavin (B2), B12, calcium, phosphorus |
Traditional buttermilk is the liquid remaining after cream or fermented milk is churned to make butter. During churning, fat globules separate to form butter. This leaves behind a thin, slightly acidic liquid. This process has been key to traditional butter-making for thousands of years. Nutritionally, buttermilk has very low fat content, usually 0.5% to 2%. Most fat is removed during butter formation. It keeps a good amount of protein, typically 3-4 grams per cup. These proteins are complete and may be easier to digest. Buttermilk also provides important nutrients like riboflavin (B2), vitamin B12, calcium, and phosphorus. These support bone health, energy, and nerve function.
Cultured Buttermilk
Cultured buttermilk is the type most people find in stores today. Manufacturers make it by adding specific bacteria cultures to milk, usually skim or low-fat milk. These bacteria ferment the milk, producing lactic acid. This acid gives cultured buttermilk its characteristic tangy taste and slightly thicker texture. It is a fermented dairy product.
How Buttermilk Is Made
The production of buttermilk differs between traditional and cultured varieties.
Traditional buttermilk production is a natural result of butter making. Cream is churned, and the butterfat separates. The remaining liquid is traditional buttermilk.
Cultured buttermilk production involves a more controlled industrial process:
Preparation: Manufacturers ferment milk with specific bacterial cultures. This creates a sour, mildly thick liquid.
Pasteurization: Milk undergoes pasteurization before culturing. This kills harmful bacteria.
Fermentation: Lactic acid bacteria culture is added to the pasteurized milk. This causes the milk to sour and thicken.
Ingredients: Key ingredients include skim milk, low-fat milk, cream, and specific cultures like Streptococcus lactis. Sometimes, salt is added.
Optional Additives: Manufacturers might add sodium citrate for flavor, butter flakes, sweeteners, or stabilizers. They may also add vitamins A and D.
Equipment: Factories use pasteurizers, fermentation vessels, and homogenizers. Homogenizers help create a smooth texture and consistent flavor.
Packaging: Aseptic packaging or carton fillings are used. This helps the product last longer during transport and storage.

Health Benefits of Buttermilk
Buttermilk offers numerous health benefits, making it a valuable addition to many diets. This fermented dairy product provides essential nutrients and beneficial compounds that support various bodily functions. Understanding the health benefits of buttermilk helps people make informed dietary choices.
Digestive Health
Buttermilk is well-known for its positive impact on digestive health. As a fermented dairy product, it contains probiotics, which are beneficial bacteria. These probiotics help maintain a healthy balance of gut flora. They promote healthy digestion and can alleviate common issues like bloating, constipation, and indigestion. For example, strains like Pediococcus pentosaceus OBK05, isolated from buttermilk, show strong tolerance to acidic stomach conditions and bile, allowing them to survive and thrive in the intestinal tract. Other beneficial bacteria found in buttermilk include Lactococcus Lactis, Lactobacillus acidophilus, and Bifidobacterium bifidum.
These healthy bacteria aid in food breakdown and nutrient absorption. Buttermilk can also be easier to digest for some individuals with lactose intolerance. The fermentation process breaks down much of the lactose, making it a gentler alternative to regular milk. The benefits of drinking buttermilk regularly include improved gut function and a stronger digestive system.
Bone Health
Buttermilk is a good source of calcium and phosphorus, both crucial for strong bones and teeth. Regular consumption supports bone density and helps prevent conditions like osteoporosis. The calcium in buttermilk is readily absorbed by the body, contributing to overall skeletal health. These health benefits are particularly important for growing children and older adults.
Blood Pressure
Research suggests that buttermilk may help manage blood pressure levels. A clinical trial investigated the impact of buttermilk consumption on blood pressure in men and women. Participants consumed buttermilk daily for four weeks. The study found that buttermilk consumption significantly reduced systolic blood pressure and mean arterial blood pressure compared to a placebo. This effect is likely due to bioactive peptides formed during the fermentation process. These peptides act as ACE inhibitors, which help relax blood vessels. The benefits of drinking buttermilk extend to cardiovascular health.
Other Health Aspects
Buttermilk offers several other health benefits. Its components can contribute to cardiovascular health. Research shows that polar lipids found in buttermilk can reduce cardiovascular risk. These lipids form a complex with cholesterol in the small intestine, preventing its absorption and leading to its excretion. This mechanism helps lower blood levels of LDL-cholesterol and triglycerides. A study involving overweight postmenopausal women demonstrated that consuming a buttermilk concentrate enriched with milk polar lipids significantly reduced cardiometabolic risk markers.
Buttermilk also supports the immune system. Probiotics enhance gut-associated lymphoid tissue, improving resistance to infections. The presence of vitamin B12 and riboflavin supports immune cell production and function. This may reduce the frequency and severity of respiratory infections. Buttermilk also contains bioactive compounds with anti-inflammatory and antioxidant properties. These compounds help lower systemic inflammation markers and protect cells from oxidative damage. This is attributed to its selenium and vitamin E content. These health benefits may reduce the risk of chronic inflammatory conditions.
Potential Downsides
While buttermilk offers many benefits, some potential downsides and risks exist. Individuals with dairy allergies should avoid buttermilk entirely. It can cause symptoms like vomiting, wheezing, hives, and even anaphylaxis. The Food Allergen Labeling and Consumer Protection Act (FALCPA) requires clear labeling for milk products.
People with lactose intolerance might find buttermilk easier to digest than regular milk due to its lower lactose content. However, those who are particularly sensitive should still exercise caution. Buttermilk is not a low-calorie food, so calorie-conscious individuals should monitor their intake.
Buttermilk can also contain a high sodium content, sometimes 300–500 mg per cup. High sodium intake is linked to an increased risk of high blood pressure, especially in salt-sensitive individuals. People with high blood pressure or kidney issues should consult a doctor before consuming buttermilk, especially if it contains added salt. Consuming cold buttermilk at night might also worsen throat infections for some individuals. These considerations help ensure safe consumption of buttermilk.
