Prebiotics are fibers and natural sugars that feed good bacteria in the gut. Cruciferous vegetables such as cabbage, collard greens, Brussels, broccoli, kale and kohlrabi are great sources of prebiotic fiber (and skin-supportive vitamins and minerals). Because cooking can alter the fiber content, it’s valuable to supplement cooked meals with raw veggies.
With the support of prebiotics, the gut microbiome helps to control the digestive and immune systems. An imbalance in the digestive microbiome may contribute to weight gain, high blood sugar, high cholesterol and unruly skin.
