Types of Active Yogurt Cultures

According to the U.S. Food and Drug Administration, yogurt is made by combining lactic acid-producing bacteria with cream or milk. Yogurt must contain both Lactobacillus bulgaricus and Streptococcus thermophilus in order to be labeled as yogurt. Other live and active cultures, such as Lactobacillus acidophilus and Bifidus, may also be found in some brands of yogurt.

  1. Heat-Treated Yogurt

    • Heat-treating yogurt extends its shelf-life and eliminates the need for refrigeration. The heat-treatment of yogurt occurs after the fermentation process, killing the live and active cultures and reducing the yogurt's health benefits. Yogurt that has been heat-treated is less tart than yogurt containing live and active cultures. Heat-treated yogurt can be identified by its label, which will read "made with active cultures." If your yogurt's label reads "contains active cultures," it has not been heat-treated and retains the live, active cultures and their health benefits..

    Benefits of Yogurt Containing Live and Active Cultures

    • Dr. Sears cites a number of health benefits associated with eating yogurt. Not only is yogurt high in protein and calcium, it can actually lower cholesterol. The live and active cultures in yogurt make it easily digestible while promoting the growth of healthy bacteria in the intestines and colon. Additionally, yogurt contains vitamins B5, B12, potassium and zinc.

    How to Select Yogurt With Live and Active Cultures

    • The National Yogurt Association (NYA) is a not-for-profit trade organization that provides information to the yogurt industry as well as the general public. Yogurt containing at least "100 million cultures per gram at the time of manufacture" earns the NYA's Live and Active Cultures Seal. Producers and distributors of yogurt must apply to use the Live and Active Cultures Seal so not all yogurt with live, active cultures will carry the seal. If you cannot find the Live and Active Cultures Seal, look for labels that read "contains active cultures" to ensure your yogurt has all the health benefits associated with live and active cultures.

    The Yogurt Alternative

    • The National Yogurt Association recommends using yogurt to increase the nutritional value of everyday meals. Plain yogurt can take the place of mayonnaise and sour cream or be used as a base for homemade salad dressings. Blended with honey and fruit, plain or vanilla yogurt makes a healthy smoothie that is sweet enough to satisfy ice cream cravings. Mix your favorite yogurt with granola and fresh fruit for breakfast to avoid feeling sluggish.
