Eat raw, lacto-fermented foods
Fermented foods are true superfoods. They contain live bacteria, also known as probiotics, and it's beneficial for gut health. Your gut may be low on good bacteria for several reasons (e.g., age, medications, antibiotics, poor diet). Eating foods like kimchi, lacto-fermented sauerkraut and vegetables, kombucha, yogurt, and kefir will supply you with a healthy dose of probiotics.
