The importance of a balance of good and bad gut bacteria as a precursor to overall good health is increasingly recognized. Fermented foods such as live yogurts, sauerkraut, kimchi, and kefir, prompt the production of digestive enzymes and contain natural probiotics, beneficial bacteria that top up gut-friendly "good" bacteria to help optimize and balance digestive health.
"Prebiotics" are natural partner to probiotics foods. A type of fiber, these feed and encourage the growth of good bacteria already present in the gut. Leeks, onions, garlic, asparagus, and bananas will all ensure you receive a good supply of prebiotics. Try to include a helping of at least one of these in your daily diet.
