The Gut Health Guide: 8 Ways to Support Your Microbiome and Digestive Wellness

Gut health has become one of the biggest conversations in wellness—and for good reason.

Your digestive system does much more than process the food you eat. The gut is part of an interconnected system that communicates with the brain and plays a role in immune health, cognitive function, mood, and overall wellbeing.

The good news? Supporting your gut doesn't necessarily require completely changing your lifestyle.

In The Gut Health Handbook, Jessica Charles explores practical strategies that can be incorporated into everyday life, including mindful eating, fiber-rich foods, fermented foods, consistent meal timing, movement, light exposure, and other wellness practices.

Here are 8 ways to build a more gut-friendly daily routine.

1. Understand the Gut-Brain Connection

Ever felt "butterflies" before an important meeting? Or completely lost your appetite during a stressful day?

There's a reason.

Your brain and digestive system communicate through what's known as the gut-brain axis. The handbook describes this as a two-way communication system connecting digestive and mental wellbeing, with the vagus nerve serving as an important communication pathway.

That means a gut-friendly lifestyle isn't only about what you eat. Stress management, sleep, movement, and your eating environment can all become part of the bigger picture.

Try this: Before your next meal, take three slow breaths and give yourself a moment to transition out of "go mode" and into mealtime.

2. Make Mindful Eating Part of Your Routine

How you eat can matter alongside what you eat.

Eating while answering emails, scrolling through your phone, or rushing out the door can make it difficult to create a calm mealtime experience.

The handbook recommends creating a relaxed environment for meals, putting away your phone, stepping away from your desk, slowing down, and chewing thoroughly.

Try turning meals into a small daily ritual:

• Sit somewhere comfortable.

• Put your phone away.

• Take three deep breaths.

• Notice the colors and aromas of your food.

• Eat slowly and chew thoroughly.

• Pay attention to how you feel as you eat.

You don't need a 30-minute wellness ritual at every meal. Even a few intentional moments can make mindful eating more realistic for a busy schedule.

3. Feed Your Microbiome With a Variety of Fiber

If you're looking for foods that support gut health, fiber deserves a place near the top of the list.

Different types of fiber play different roles.

Soluble fiber is found in foods such as oats, legumes, apples, and citrus fruits. Gut bacteria can ferment this fiber and produce short-chain fatty acids.

Insoluble fiber, found in vegetables, whole grains, and nuts, helps support movement through the digestive system.

Then there are prebiotic fibers, including inulin and fructooligosaccharides (FOS). These fibers provide food for beneficial gut bacteria and can be found in foods such as garlic, onions, and Jerusalem artichokes.

The goal isn't necessarily to load your plate with as much fiber as possible overnight.

Variety and consistency matter.

The handbook recommends introducing different fiber sources gradually and increasing water intake as fiber consumption rises.

4. Experiment With Fermented Foods

Fermented foods have been part of traditional diets for generations.

Options highlighted in the handbook include:

Sauerkraut: A fermented food containing probiotics, organic acids, enzymes, and other compounds produced through fermentation.

Kimchi: Combines fermented vegetables with herbs and other ingredients, creating a varied mixture of fermentation-derived compounds.

Water kefir: A fermented beverage that can contain diverse probiotic strains and fermentation compounds.

Raw apple cider vinegar with "the mother": Another traditional fermented ingredient discussed in the guide.

If fermented foods aren't already part of your diet, there's no need to go from zero to a refrigerator filled with sauerkraut overnight.

The handbook's approach is simple: start small and gradually increase your intake while paying attention to how your body responds.

5. Give Your Gut a Consistent Daily Rhythm

Your digestive system operates according to natural rhythms.

One process discussed in The Gut Health Handbook is the migrating motor complex (MMC), which becomes active during periods without food. The guide suggests consistent meal timing and an overnight fasting window as ways of aligning eating habits with these digestive rhythms.

Rather than focusing on extreme fasting protocols, think about consistency.

For example, finishing dinner in the evening and eating breakfast the following morning can naturally create a period without food overnight.

The handbook suggests beginning with a 12-hour overnight window and adjusting according to individual comfort.

6. Take a Short Walk After Meals

One of the easiest gut-friendly habits doesn't require a supplement, complicated recipe, or specialized equipment.

Just walk.

The handbook recommends 10–15 minutes of gentle movement after eating, describing post-meal walking as a way to support digestive movement and blood flow. It also recommends leaving more time between eating and vigorous exercise.

Can't fit in a full walk?

Even several minutes of standing and gentle movement after eating can be an easy place to start.

Try pairing the habit with something you already do:

Lunch → 10-minute walk → back to work.

Simple habits are often the easiest ones to maintain.

7. Get Morning Light

Your gut doesn't operate independently of the rest of your body's internal clock.

The handbook recommends spending 5–10 minutes outside within an hour of waking, potentially combining morning light with gentle movement and hydration.

This can be surprisingly easy to incorporate into your routine.

Drink your morning coffee outside. Walk around the block. Take the dog out. Sit on your patio for a few minutes.

You're not adding another complicated wellness task—you're simply moving something you already do outdoors.

8. Explore Red Light Therapy as Part of Your Wellness Routine

For those interested in taking their routine further, the handbook also explores red and near-infrared light therapy.

It discusses wavelengths around 630–670 nm and 810–850 nm and describes their potential application to digestive wellness, including cellular energy production, circulation, inflammation, and intestinal barrier support.

Jessica Charles incorporates targeted red light therapy into her own morning routine, using approximately 10 minutes of light over the abdominal area alongside breathing practices. The guide specifically mentions the Nushape Therapy Wrap and Lipo Wrap for this type of targeted application.

For anyone building a broader wellness routine, light therapy can be one tool to explore alongside nutrition, movement, sleep, and stress management rather than viewing any single practice as the entire solution.

Build Your Gut Health Routine One Habit at a Time

A better gut-health routine doesn't have to begin with a dramatic lifestyle overhaul.

Start with one habit.

Add more fiber variety to your meals. Try fermented foods. Put your phone away while you eat. Walk for 10 minutes after dinner. Get outside after waking. Create a more consistent eating schedule.

Then pay attention to how you feel.

That's ultimately one of the central messages of The Gut Health Handbook: start where you are, make gradual changes, and listen to your body's response.

Small habits become routines. And routines can create the foundation for a more intentional approach to digestive and whole-body wellness.
