Prebiotics are compounds in food that induce the growth or activity of beneficial microorganisms such as bacteria and fungi. The most common example is in the gastrointestinal tract, where prebiotics can alter the composition of organisms in the gut microbiome.
The difference between a probiotic and a prebiotic is probiotics are beneficial bacterial and prebiotics are the foods that feed the bacteria. Having a healthy gut is the most important thing for your overall health. Many people eat plain yogurt because it has active cultures which nourish for your gut, which is a probiotic. There are a number of different foods that will produce the right organisms to feed a healthy gut. They are also very high in fiber and good for your colon. For example: pickles (made without sugar), Kimchee, sauerkraut, leeks, jicama, fermented asparagus, daikon, Jerusalem artichokes, dandelion greens, chicory root, garlic, onions, green bananas, burdock root, flaxseeds, and seaweed.
Eating prebiotics daily will help with digestive problems and boost your immune system.
I make a prebiotic salad and it is delicious and a great way to get my prebiotics eaten every day.
