Difference between Yogurt and Kefir
Yogurt and Kefir both are cultured milk products which are rich in probiotics and proteins. Both start out as milk, both are fermented and both have a tart and slightly sour taste, yet they are completely different. Let us see how Yogurt differs from Kefir.
Yogurt is a cultured milk product made from the bacterial fermentation of milk. It can be of numerous types with varying fat content. According to the guidelines of FDA, yogurt must contain "live and active" bacterial cultures like Lactobacillus bulgaricus and Streptococcus thermophiles. Yogurt has transient beneficial bacteria that don not colonize the gut but helps clean the digestive system and provide food for the good bacteria present in the digestive system. It takes around four to six hours to produce yogurt by fermenting the milk at a temperature of around 43 degree centigrade.
Kefir is also a cultured milk product which is made by fermenting milk with bacteria and yeast at room temperature for around 15-20 hours. It has a thinner consistency than yogurt and is generally sold as a beverage. You can drink it or blend it with fruits to make smoothies or can substitute for yogurt in many dishes. Kefir is fermented for a longer period of time than yogurt and contains three times more probiotics than yogurt.
To produce Kefir, milk is fermented with kefir grains which comprise different types of bacteria and yeasts. Kefir contains several strains of good bacteria which are not commonly found in yogurt. It also contains beneficial yeasts like Saccharomyces kefir and Torula kefir which help control and eliminate bad pathogenic yeasts present in the body.
Furthermore, Kefir provides more nutrition than yogurt as it helps digest the foods that we eat. It is also easy to digest as compared to yogurt which makes it an ideal nutritious food for babies, the elderly and people with poor digestion or other digestive disorders.
Based on the above information, some of the key differences between Yogurt and Kefir are as follows:
