Live Active Cultures: L

Live active cultures are beneficial bacteria and yeasts that are added to foods, most commonly dairy products like yogurt and kefir. These microorganisms are naturally present in fermented foods and are often added to enhance the food's nutritional profile and digestive properties. They are typically introduced during the fermentation process.

Live active cultures are added to foods primarily for their probiotic benefits, which are thought to support gut health. They are most frequently found in fermented dairy products such as yogurt, kefir, and some cheeses. They can also be added to other products like fermented beverages and dietary supplements.

Live active cultures are generally recognized as safe (GRAS) by the FDA for use in foods. While not a regulated additive in the same way as preservatives or colors, specific strains may be subject to review. International bodies like the WHO and EFSA have evaluated probiotics, acknowledging their potential health benefits, particularly for gut health. Research is ongoing to fully understand the long-term effects and specific benefits of various strains.
