Name a common source of probiotics.

Yogurt and fermented foods are widely recognized as common sources of probiotics. Probiotics are beneficial live bacteria that contribute to gut health and overall well-being. Yogurt, particularly those labeled as containing live and active cultures, is made through the fermentation of milk, where beneficial bacteria are introduced. This process not only imparts a distinctive taste and texture but also enhances the yogurt's nutritional profile by adding these live microorganisms.

Similarly, other fermented foods such as kefir, sauerkraut, kimchi, miso, and kombucha also serve as excellent sources of probiotics. These foods undergo fermentation, which allows for the growth of beneficial bacteria that can promote digestive health, support the immune system, and increase nutrient absorption.

In contrast, options like cheese might contain probiotics, but not all cheeses are fermented to the same extent or contain live cultures. Bread typically does not provide a significant source of probiotics unless specifically made with fermented ingredients. Rice is primarily a carbohydrate source and lacks the beneficial bacteria found in probiotic-rich foods. Thus, yogurt and fermented foods stand out as the most reliable sources of probiotics.
