What is Gut Health? A Beginner’s Guide to the Microbiome

Key Takeaways:

  • Gut health refers to how well your digestive system and microbiome work together to support digestion.1
  • The gut microbiome is made up of trillions of microorganisms that help break down food, support digestion, and maintain balance in the digestive tract.1
  • Prebiotic fiber helps nourish beneficial gut bacteria and can support digestive health and regularity.4
  • Eating fiber-rich foods, staying hydrated and maintaining balanced daily habits can help support a healthy gut environment.3
  • Benefiber Original Powder contains one ingredient: wheat dextrin, a plant-based prebiotic fiber that is gluten and sugar-free.

Gut health has become a popularized topic when it comes to the health and wellness space, but many people still don’t know what it is or how to achieve it.1

The term itself refers to the balance and function of the digestive system and the microorganisms that live within it, known as the gut microbiome.1 A healthy gut can help support bodily functions including digestion and regularity.1

The gut microbiome contains trillions of microorganisms, including beneficial bacteria that help break down food and support the digestive process.1 Daily habits like eating fiber-rich foods and supporting beneficial bacteria with prebiotic fiber may help to maintain gut balance.4

Explaining the Gut

Gut health is often used to describe how well your digestive system functions and how balanced your gut microbiome is. Your digestive system helps to break down food, absorb nutrients, and remove waste, while the gut microbiome consists of microorganisms that naturally live in your digestive tract.1

When your gut microbiome is balanced, beneficial bacteria can help support normal digestive processes and perform functions that contribute to maintaining the gut environment.2 Maintaining gut health means taking care of things like:

  • Diet
  • Hydration
  • Lifestyle habits
  • Fiber intake5

Explaining the Microbiome

A microbiome refers to the community of microorganisms, so the gut is the community of microorganisms that live in your digestive system. This includes:

  • Bacteria
  • Fungi
  • Viruses

It also includes other microbes that work together within the digestive tract.1

Many of these microorganisms are considered beneficial because they help to break down food and support digestion. The foods and nutrients you consume can influence the balance of bacteria within the microbiome, which is why dietary habits are often discussed alongside gut health.2

The microbiome is unique to each person and can change over time based on different factors like diet, lifestyle, age, and environment.1

Why Does Gut Health Matter So Much?

Your digestive system plays an important role in everyday wellness. Digestive comfort, regularity, and nutrient absorption are all directly connected to how your gut functions.2

A balanced gut environment may help support:

  • Digestive regularity
  • Comfortable digestion
  • Nutrient absorption2

Many people begin focusing on gut health when they notice occasional digestive discomfort or when trying to improve overall health, however, maintaining gut health is an ongoing process. Small, consistent dietary changes may help support healthy digestion over time.5

Signs Your Gut May Need Support

Everyone experiences digestive changes from time to time, especially during periods of stress, travel, diet changes, or inconsistencies in their routine.

Some behaviors and risk factors that may indicate that your gut needs extra support can include:

  • Digestive discomfort
  • Inconsistent eating habits
  • Irregular digestion
  • Not eating enough fruits, vegetables, or whole grains2

Building more balanced daily habits and increasing fiber intake gradually may help support digestive wellness.5

How to Support a Healthy Gut

Supporting a healthy gut often starts with simple daily habits, and consistency is typically more important than making major overnight changes.2

Eat More Gut-Friendly Foods

Fiber helps support digestive health and regularity, and there are many foods that contain prebiotics and probiotics, which help to nourish beneficial gut bacteria.5

Foods that can benefit your gut health:

  • Colorful vegetables, fruits and legumes
  • Whole grains, nuts and seeds
  • Olives
  • Fatty fish like sardines, salmon, and anchovies
  • Fermented dairy products with live cultures, as well as fermented foods such as (kimchi, sauerkraut, kombucha)2

Some foods also contain prebiotic fibers, which help feed beneficial bacteria in the gut microbiome.3

Stay Hydrated

Hydration is an important part of digestive wellness. Drinking enough water may help to support normal digestion and can work alongside fiber as part of a balanced digestive routine.5

Support Your Gut with Prebiotic Fiber

Prebiotic fiber supplements can help nourish beneficial bacteria already living in the gut’s microbiome. Unlike probiotics, which are live microorganisms, prebiotics act as a food source for beneficial gut bacteria.4

Things like Benefiber Original Powder are beneficial sources of prebiotic fiber. Benefiber contains one ingredient, wheat dextrin, which is a plant-based prebiotic fiber that is gluten-free and sugar-free. It comes as a powder which can easily be incorporated into foods and beverages as part of a daily routine.

Prebiotics Vs. Probiotics: What’s the Difference?

Both prebiotics and probiotics are commonly discussed in conversations about gut health, but it’s important to note that they work and operate differently from each other:4

Prebiotics

Probiotics

Feed beneficial gut bacteria

Introduce live microorganisms

Often found in fiber-rich foods and prebiotic fiber supplements

Often found in fermented foods and probiotic supplements

While prebiotics and probiotics may work differently to tackle gut wellness, they often can work together as part of an overall gut-friendly lifestyle.4 Try Benefiber Dual Action Biotic + Stress Relief* Stick Packs to provide a convenient source of prebiotics and probiotics as part of your daily routine.

How Fiber Supports Digestive Health

Busy schedules, travel, and inconsistent meal routines can sometimes make it difficult to get enough fiber through just food alone, which is where a fiber supplement like Benefiber Original Powder comes in.

A fiber supplement may be helpful when:

  • Your diet lacks fiber-rich foods
  • You are trying to increase fiber intake gradually
  • You want a convenient addition to meals or beverages
  • You are looking for a prebiotic fiber supplement option5

Fiber helps support digestive health and regularity. Soluble fiber dissolves in water and forms a gel-like material, while insoluble fiber helps move food through the digestive system. Both types of fiber can play a role in maintaining digestive wellness. It’s important to recognize areas where you can improve or add to your diet to support long-term digestive wellness habits.2
