"Fermented foods have been around for centuries but are seeing a resurgence in popularity. Some fermented foods, like miso, contain probiotic bacteria, which may be beneficial for gut health," Ali told POPSUGAR. Miso is a paste made from fermented soybeans, salt, and a fungus called koji. Ali recommends it because of its versatility. "This paste can be used for everything from miso soup to sauces and as a part of main dishes," she said. "There are several different types of miso (including red, white, yellow, and black), and each imparts a different flavour profile on the foods it's cooked with."
She noted that, while miso paste can deliver small amounts of vitamins and minerals, it may be too high in sodium for people who are watching their salt intake.
