Probiotics are beneficial microorganisms for those who consume them. This microorgansims can be found in different fermented foods with active cultures such as yogurt and other supplements. Some of these supplements have good organisms that are found in soil instead of those found on diary. Probiotics are very important for a correct intestinal and digestive function because they balance the microflora found in this system. In the past, people used to eat vegetables and fruits that came with dirt and soil and it remained a little even if they washed them with water. Now, vegetables are sold at the supermarket totally clean. This prevents us from taking in good soil bacteria as well; the beneficial bacteria that helps us to regulate the immune system and protect us from the overgrowth of harmful bacteria and fungi. When you reintroduce soil organisms to your intestines, you increase the diversity of good bacteria in your gut, improving digestion, boosting the immune system and stimulating the production of white blood cells and antibodies.
