What Are Live Cultures in Yogurt?
Yogurt has been consumed for centuries and is well-known for its numerous health benefits. One of the key components that make yogurt so beneficial is the presence of live cultures. Live cultures are bacteria that are added to milk to ferment it and produce yogurt. These bacteria are also known as probiotics and contribute to the health-promoting properties of yogurt.
Probiotics are live microorganisms that, when consumed in adequate amounts, provide health benefits to the host. They are primarily strains of bacteria, such as Lactobacillus bulgaricus and Streptococcus thermophilus, which are responsible for the fermentation process in yogurt. These beneficial bacteria help break down lactose, the natural sugar found in milk, making yogurt easier to digest for those who are lactose intolerant.
Not all yogurts contain live cultures. Some commercial yogurts are heat-treated after fermentation to extend their shelf life, which kills the live bacteria. To ensure you are getting the benefits of live cultures, look for labels that specifically state “contains live and active cultures.”
