Miso soup. This tofu and vegetable broth is high in protein as well as probiotics such as lactobacilli and bifidus bacteria.

Pickles. These fermented cucumbers are a popular source of healthy gut bacteria as well as iron, potassium, and fiber.

Kimchi. This spicy and sour form of Asian sauerkraut is often served with Korean food. In addition to its probiotic bacteria, it contains beta-carotene, calcium, iron, and vitamins A, B, and C.
