Yogurt and kefir are both dairy products made from fermented milk. Kefir is a liquid milk beverage. It has an acidic, creamy taste. Yogurt is thick and almost always eaten with a spoon. It can be used as a base in smoothies or sauces. Plain yogurt usually has a tart taste, but you can buy it sweetened or flavored, sometimes with honey, vanilla, or fruit.
Kefir is made by combining milk or water with a gelatinous kefir starter culture of bacteria, milk proteins, and yeast. Kefir can be produced with any type of milk, including:
- full-fat animal milk
- low-fat animal milk
- other dairy-free milk
Some kefir is made with coconut water.
Kefir is typically fermented for 14 to 18 hours at room temperature.
The process of making yogurt is similar to kefir, but it’s fermented for less time (two to four hours) and is often cultured under heat.
Kefir has slightly less sugar than yogurt, but it depends on which brand you buy. The biggest nutritional difference between the two is that kefir contains more probiotics than yogurt. While yogurt also contains some probiotics, kefir is more potent. If you are looking to improve digestion or gut health, kefir is the better choice.
