Author : Priyanka | January 7, 2024

There are a variety of supplements and medications that we use to alleviate digestive problems, but are there any natural methods or foods that can provide relief for gastrointestinal issues? The answer is yes - probiotics. They are found in different food sources and offer a range of health benefits, particularly for the digestive system.

Now, let's delve into comprehending how probiotic foods contribute to maintaining good health.

What are Probiotics Exactly?

Probiotics are live bacteria and yeasts that are beneficial, especially for the digestive system. Contrary to the common association of disease-causing bacteria, the body contains both good and bad bacteria, with probiotics being referred to as "good" or "helpful" bacteria due to their role in maintaining gut health. Probiotics can be found in supplements and foods like yogurt, kefir, and cottage cheese. They are known for their potential to promote digestive health, support immunity, manage inflammation, and potentially reduce the risk of certain conditions, such as asthma and other respiratory diseases. According to a recent report published by Kings Research, the global probiotics market is expected to attain $126.34 billion in revenue by 2030.

How do Probiotics Work?

Probiotics support the beneficial microbes in your body. Numerous probiotic products contain helpful bacteria and yeasts, aiming to prevent or recover from bacterial or yeast infections in various body parts, such as atopic dermatitis, acne, cavities, and gum disease. They also support the body in the following ways:

  • It can support the body in maintaining a healthy community of microorganisms.

These microorganisms can have different effects on the body, and the combination of probiotic and prebiotic foods in synbiotic products also significantly impacts overall health.
