As medical research continues to point to digestive health as the foundation for a person’s overall health, both nutrition consultancies and food distributors have identified “gut-healthy foods” as a top food trend for 2019. Food Business News reports that probiotics are finding their way into products such as granola, oatmeal, nut butters and soups. The good news is that it’s easy for restaurants to accommodate the trend. To give your menu a probiotic boost, incorporate cultured or fermented foods like buttermilk, kefir, tempeh, sauerkraut and yogurt. For prebiotic fiber, try bananas as well as asparagus, garlic, leeks and onions.
