In our bowels live about a million types of bacteria. There are the good ones and the bad ones. For a healthy body it is vital that the number of good bacteria is greater than the bad ones. For a healthy micro flora in our bowels we need prebiotics, indigestible fibers which the good bacteria (probiotics) use as food. Prebiotics selectively enhance growth and activity of probiotics and affect the body positively. To date the most famous prebiotic is inulin. Inulin is a plant polymer which serves as a reserve carbohydrate and in different quantities in present in more than 36 thousand plants. You can find loads of inuline in vegetebles such as: artichokes, chicory, onions and garlic. It can also be found in dandelion flowers. Because inulin has a lower caloric value than other carbs it's used as a replacement for regular sugar in sweets, ice-cream, dairy products and baked goods.
