What Is Kefir?
Kefir is a traditional fermented drink made by adding small cultures called kefir grains—a mixture of yeast and beneficial bacteria—to milk. It originated in the Caucasus region. The mild sourness and fizz that develop during fermentation are characteristic features.
Although similar to yogurt, kefir is thinner and contains a greater diversity of microorganisms. Its drinkable consistency makes it suitable both plain and in smoothies and sauces.
Kefir Nutrition Facts
Kefir is a fermented drink that retains milk’s nutritional value. 100 milliliters of plain kefir contain about 41 kcal, 3.8 g of protein, and 130 mg of calcium. Its main distinguishing features are its probiotic microorganisms and the fact that some of the lactose is transformed during fermentation.
What Are the Benefits of Kefir?
As a fermented product, kefir has traditionally been consumed to support digestion. Studies suggest that its probiotics may help support the gut microbiota; research in this area is ongoing.
This is general information. Kefir is a food and is not a substitute for medical treatment. People with a milk-protein allergy are advised to use caution.
How to Choose Kefir
Good-quality kefir is uniform, slightly fizzy, and has a fresh sour smell. Prefer products whose labels say they contain live cultures.
- Check the expiration date and whether the product has been kept in the cold chain.
- The label should state that it contains live cultures (probiotics).
- Excessively puffed or swollen packaging may indicate spoilage.
How to Store Kefir
Always store kefir in the refrigerator with the container sealed. Consume unopened kefir by the date on its label, and consume it within a few days after opening. It may naturally become a little more sour over time; shake it to recombine any separated liquid.
How to Use Kefir in the Kitchen
Kefir is most often enjoyed plain, but it is also versatile in the kitchen. Because it is sensitive to heat, use it in uncooked, cold recipes if you want to preserve its live cultures.
How to Make a Kefir Smoothie
Blend one glass of kefir with fruit such as banana, strawberries, or blueberries and, if desired, one spoonful of oats. It makes a filling, refreshing drink for breakfast or a snack.
In Sauces and Marinades
Whisk kefir with garlic, dill, and salt for a light salad dressing or appetizer dip. Its mild acidity can also help tenderize meat in chicken marinades.
What Recipes Use Kefir?
Kefir smoothies, kefir breakfast bowls, kefir salad dressings, kefir cakes, and cold soups are common uses. When a recipe calls for it, kefir can also replace ayran or thinned yogurt.
Frequently Asked Questions
What is kefir good for?
Kefir is a fermented, probiotic drink traditionally consumed to support digestion. Studies suggest it may help support the gut microbiota; it is a food and is not claimed to cure disease.
What is the difference between kefir and yogurt?

How much kefir can you drink per day?
For most people, 1–2 glasses of kefir per day is considered a balanced amount. People new to fermented foods may find it easier on digestion to start with a small amount and increase gradually.
Does kefir contain lactose?
Some of the lactose in milk is transformed during fermentation, so some people may find kefir easier to consume than milk. However, it is not completely lactose-free; people with a sensitivity are advised to use caution.
Can you heat kefir?
Kefir is sensitive to heat; boiling it greatly reduces the activity of its live cultures. To preserve its probiotic value, it is best enjoyed plain or in cold recipes.
