By now, everyone has heard a lot about probiotics or "good bacteria" for your GI tract, but many people don't know as much about prebiotics and how they help the gut.
Probiotics are good bacteria that help with digestion and more, and more research is on the rise correlating probiotics and many different ailments. You can get them in capsule form or eat more probiotic-rich foods like yogurt, kefir, kimchi, sauerkraut, and miso. Prebiotics, on the other hand, are food for the probiotics to eat.
Prebiotics are nondigestive fiber in the large intestine that stimulates and enhances the growth of probiotics. Butyric acid is a by-product that is produced when the good bacteria break down the prebiotic fiber-rich foods. When this happens, it makes it less likely that the "bad bacteria" will survive and colonize the colon, so you need both probiotics and prebiotics for your GI tract to stay healthy.
When probiotics have enough prebiotics-rich food to eat, your gut will work optimally, function better, and you'll be healthier because your gut bacteria is happy and fed well.
Prebiotic fiber is also shown to help with weight management and encourage weight loss. Try to aim for 5 grams of prebiotic foods a day. There are additional inulin prebiotics supplements you can take, but I always encourage getting your nutrition through your diet first.
These are five prebiotics foods you didn't realize you were eating, so I encourage you to eat more to feed your friendly bacteria in your gut!
