The Gut-Brain Connection: 11 Fermented Foods That Can Boost Your Mood

7. Natto: Japan's Fermented Soybean Secret

Natto, a traditional Japanese food made from fermented soybeans, is known for its distinctive smell, strong flavor, and sticky texture. Despite its polarizing characteristics, natto is a nutritional gem, rich in protein, vitamins, and nattokinase, an enzyme with potential cardiovascular benefits. The fermentation process produces Bacillus subtilis, a probiotic that supports digestive health. Natto's unique composition may also aid in mood regulation, as its high levels of vitamin K2 and nattokinase have been linked to improved mental function and reduced anxiety, highlighting its multifaceted impact on health.

8. Yogurt: The Classic Fermented Dairy Delight

Yogurt, one of the most popular fermented foods globally, is made by fermenting milk with live bacteria cultures, primarily Lactobacillus bulgaricus and Streptococcus thermophilus. This process thickens the milk and imparts a tangy flavor. Yogurt is a rich source of probiotics, calcium, and protein, making it a staple in many diets. Regular consumption of yogurt is associated with improved digestion, enhanced immune response, and potentially better mood regulation due to the gut-brain axis. Its versatility allows it to be enjoyed on its own, in smoothies, or as a base for dressings and desserts.
