1. Yogurt is made from milk that has been fermented, typically by lactic acid bacteria.
It contains friendly bacteria known as probiotics, which are good bacteria that live in your digestive tract and can help improve digestion, keeping your gut healthy.
2. Apples are a rich source of pectin, a soluble fiber.
Pectin bypasses digestion in your small intestine and is then broken down by the friendly bacteria in your colon.
3. Commonly consumed in miso soup, miso is made by fermenting soybeans with salt and koji, a type of fungus.
Miso contains probiotics that, like other fermented foods, help improve digestion by increasing the good bacteria in your gut.
