What Are Probiotics and How Do They Help the Body?

 

Probiotics are live bacteria and yeasts that are good for your health—especially your digestive system. While we often think of bacteria as harmful, our bodies are full of both good and bad bacteria. Probiotics are often called “good” or “friendly” bacteria because they help keep your gut healthy.

These beneficial microorganisms play a major role in maintaining a balanced gut microbiome. They aid digestion, help the body absorb nutrients, and support the immune system. Probiotics also help prevent and treat diarrhea, especially after taking antibiotics that kill off both harmful and good bacteria. They may even reduce symptoms of digestive disorders like irritable bowel syndrome (IBS) and bloating.

In addition to digestive health, emerging research shows that probiotics may support mental wellness, heart health, and even skin conditions by reducing inflammation and boosting the immune response.

🌱 Common Sources of Probiotics

Probiotics occur naturally in some foods and are also available as supplements. Here are some common food sources:

• Yogurt – Made from fermented milk, it’s one of the most widely available probiotic foods.

• Kefir – A fermented milk drink that’s rich in various strains of bacteria and yeast.

• Sauerkraut – Fermented cabbage, especially the unpasteurized kind.

• Kimchi – A spicy Korean side dish made from fermented vegetables.

• Miso & Tempeh – Fermented soy products common in Asian cuisine.

• Pickles (fermented in brine) – Not vinegar-pickled, but saltwater-fermented.

Adding these foods to your diet regularly can promote a healthy gut, improve digestion, and boost your overall well-being.
