Microbiome

Gut Health.

Probiotics and Prebiotics can make a difference.

As interest has increased in the gut microbiome and gut health, a number of products have entered the market that claim to help foster a healthy gut environment. The most popular are probiotics and prebiotics, and the two are often confused. While both are useful, they serve different purposes in cultivating and maintaining intestinal health.

What are Probiotics? 

According to the WHO, probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Several varieties of both yeast and bacteria are used in probiotic supplements; the most common are lactobacilli and bifidobacteria strains.1 However, not all probiotics are equal, and this is especially true with respect to infants.

Historically, probiotics have been taken with the hope to relieve symptoms such as gas, bloating, or other digestive issues.1 However, new research has found that gut health is connected to other conditions such as eczema, allergies, obesity, and diabetes. Probiotics may have a much larger impact on overall health, and not just the health of the gastrointestinal system.2-4

What about Prebiotics?

A dietary prebiotic, on the other hand, is a component of food that selectively feeds intestinal bacteria. To be termed a “prebiotic,” a substrate must be selectively utilized by bacteria, so not all carbohydrates are prebiotics.6
