Maintaining a healthy immune system is essential for overall well-being. One way to support your immune system is by incorporating fermented foods into your diet. Fermentation is the process of using microorganisms, such as bacteria and yeast, to convert sugars and starches in food into beneficial compounds like probiotics, enzymes, and vitamins. These compounds not only improve digestive health but also boost the immune system. Here are ten fermented foods that can help strengthen your body's defenses.

1. Yogurt

Yogurt is a popular fermented food made from milk and bacterial cultures. The bacteria in yogurt, such as Lactobacillus acidophilus and Bifidobacterium lactis, help maintain a healthy gut microbiome and support the immune system. Yogurt is also rich in calcium, vitamin D, and protein, making it an excellent addition to a healthy diet.

2. Kefir
