Understanding the Role of Probiotics
Recent research highlights the incredible diversity of bacteria on Earth, with over a trillion species, many of which are harmless or beneficial for health. While some can cause illness, probiotics are live microbes that support bodily wellness. They promote growth of friendly bacteria in our gut, aiding digestion and overall health. Consuming probiotic-rich foods or supplements can help prevent various ailments linked to lifestyle. Historically, fermented foods like yogurt, sauerkraut, and kimchi have been used for their health benefits, dating back to ancient civilizations.

Yogurt and sour milk contain Lactobacillus bacteria, beneficial for gut health.
Historically, sour milk was used in hot climates like the Middle East and Asia to treat intestinal issues. Modern science supports the idea that beneficial microbes can replace harmful ones in our digestive system, a concept introduced by Russian scientist Elie Metchnikoff who studied the longevity of people consuming fermented dairy.
