We Compare the Benefits of Prebiotics vs Probiotics: Which Is Right for You?

If you’ve been looking for ways to improve your gut health, you’ve probably come across the prebiotics vs probiotics discussion. While they’re often considered together, prebiotics and probiotics play different but complementary roles in supporting your digestive health. Both are essential for a healthy gut microbiome, which influences digestion, immune function and your overall health. 

In this article, we’ll explain what prebiotics and probiotics are, highlight which foods contain them, and explore their benefits, so you can determine how they factor into your wellness routine and health goals.

A diverse, well-balanced eating plan helps prevent chronic diseases and supports you in living the healthiest life possible. At Cary Medical Group, we provide comprehensive nutritional services for Triangle residents who want to enhance their long-term health. We invite you to contact us today for more information. 

What Are Prebiotics?

Your digestive system is made up of trillions of microorganisms, mostly bacteria, known as the gut microbiome. When the balance of beneficial and harmful gut bacteria is disrupted, digestive problems and other health issues may occur. 

Prebiotics and probiotics are nutritional elements that work together to support a healthy gut microbiome; the right balance of both can help improve digestive health and immune function. 

Prebiotics are plant fibers that act as fuel to nourish the beneficial bacteria already living in your gut. Prebiotics help these healthy bacteria grow and thrive.

Your body doesn’t digest these fibers directly. Instead, prebiotics travel to the large intestine where they are broken down and fermented by beneficial bacteria. This process creates helpful compounds that support digestive health. 

What Are Probiotics?

Live beneficial microorganisms, usually bacteria or yeast, already live in your gut. These existing naturally occurring microbes are considered part of what’s known as your gut microbiota.

They can also be introduced through certain foods that provide health benefits when eaten in sufficient amounts, called probiotics. 

So, while prebiotics feed existing bacteria, probiotics add new beneficial microbes, or “good bacteria,” into your gut. This helps maintain the balance of good and harmful bacteria, aids in digestion and supports immune function.

It’s not a question of which of these two nutritional tools is best, a healthy, well-balanced diet typically includes both prebiotics and probiotics. 

What Are the Benefits of Prebiotics and Probiotics?

Prebiotics and probiotics serve different purposes and work together to contribute to a healthy gut microbiome where beneficial bacteria can grow and function effectively.

Benefits of prebiotics may include:

• Improved calcium absorption
• Better immune system function 
• Lower risk of colon cancer 
• Healthy blood sugar control
• Increased diversity of beneficial gut bacteria 

Benefits of probiotics may include:

• Improved digestion
• Restoring gut bacteria after illness or antibiotic use 
• Fewer digestive issues like diarrhea, irritable bowel syndrome, gas or constipation

• Prevention of harmful bacteria from growing in the body

While probiotic and prebiotic foods are typically safe for most healthy adults, some mild side effects may occur, such as gas, bloating and mild digestive discomfort. These are usually temporary and resolve after a few days.

Which Foods Are Prebiotic?

Prebiotics are found naturally in many high-fiber plant foods. These foods contain compounds like inulin, pectin and resistant starch that supply fuel to beneficial bacteria and help promote digestive health.

Foods that contain prebiotics include:

Vegetables

• Garlic 
• Onions
• Leeks
• Artichokes
• Asparagus

Fruits

• Apples 
• Bananas
• Berries
• Grapefruit

Grains and legumes

• Oats
• Barley 
• Whole wheat
• Beans and lentils

Eating a variety of these fiber-rich plant foods not only support a healthy microbiome, but also provides essential vitamins, minerals and antioxidants that help maintain your overall health.

Which Foods Are Probiotic?

Probiotics are commonly found in fermented foods that contain live beneficial microorganisms. These foods are produced through processes that allow the helpful bacteria or yeast to grow. 

Probiotic foods include:

Dairy products

• Kefir (a fermented milk drink)
• Yogurt with live cultures 
• Certain cheeses, such as aged cheddar, Gruyere, Parmesan and others 

Fermented vegetables

• Kimchi
• Sauerkraut
• Pickled vegetables

Other fermented foods containing probiotics include:

• Miso 
• Tempeh
• Kombucha 

Probiotics are available in supplement form as well, though we recommend getting probiotics from food sources when possible. Fermented foods provide beneficial microbes in addition to other nutrients that support overall health.
