Gut Health Heroes for Kids

A Foundation for Lifelong Health

As parents, we all want the best for our children—especially when it comes to their health. More and more awareness has come to parents that the root of many chronic health issues begins in the gut. From immunity to mood, metabolism to skin, your child’s gut plays a far more significant role in overall wellness than we once thought. 

Why Gut Health Matters

The gut microbiome is a complex ecosystem of trillions of microorganisms living in our digestive tract. We have more microbes in our guts than we have cells in our bodies!!  These microbes do more than just digest food—they influence everything from brain function, immune strength and even our very DNA expression! In fact, we now know that 70–80% of the immune system resides in the gut!  

Learning Issues – gut 

Allergies – gut

Asthma – gut

Skin Conditions –gut

We all have experienced digestive symptoms like gas, bloating, constipation, and diarrhea at some point in our lifetimes…but…

Research also shows that imbalances in the gut can contribute to more than just digestive issues.  Gut imbalances can also impact:

• Weight struggles and metabolic issues
• Blood sugar dysregulation and diabetes
• Poor detoxification
• Mood disorders (anxiety & depression, brain fog)
• Hormonal imbalances and sleep issues
• Skin problems like acne and eczema

Gut Health Begins Early

The foundation of gut health begins in the womb and continues developing through birth and infancy. Key early-life factors like vaginal birth vs. C-section and breastfeeding vs. formula feeding can influence the microbiome’s development.

The first 1,000 days of life are especially critical. These early experiences shape a child's gut flora—and, by extension, their lifelong health.  

Four main types of microbes reside in your child’s gut:

• Parasitic
• Bacterial
• Fungal
• Yeast

When any one of these types of microbes gets out of balance (dysbiosis) the bad (opportunistic) microbes that lead to more serious issues become overgrown and out number the good (commensal) beneficial microbes…we then have an infection state that can cause systemic inflammatory conditions and many unwanted health issues that may or may not seem connected to the gut directly.

Gut Health Benefits of Vaginal Births Compared to C-Sections

1. Microbial Seeding During Vaginal Delivery

• During a vaginal birth, babies are exposed to the mother’s vaginal and intestinal flora. This initial exposure "seeds" the baby’s gut with beneficial microbes like Lactobacillus and Bifidobacterium.
• These beneficial bacteria help jumpstart the development of a healthy gut microbiome, which supports digestion, nutrient absorption, and immune system maturation.

2. Immune System Programming

• The gut microbiome trained during vaginal birth helps prime the infant’s immune system, reducing the risk of:
• Allergies
• Asthma
• Autoimmune disorders
• Inflammatory conditions later in life

3. Improved Digestive and Metabolic Health

• Babies born vaginally generally have a more diverse microbiome, which is associated with:
• Lower risk of obesity
• Better blood sugar regulation
• More efficient digestion and absorption of nutrients

4. Reduced Risk of Infections and Chronic Conditions

• Because their microbiome is more robust, vaginally born infants tend to have fewer infections early in life and may be less prone to chronic issues like:
• Eczema
• Food sensitivities
• Irritable bowel conditions

Babies born via C-section are often colonized first by skin-associated and environmental bacteria (from the hospital), which can delay healthy gut flora development. This can lead to:

• Lower microbial diversity
• Increased risk for inflammatory and metabolic disorders
• Greater susceptibility to infections and allergies

However, not all is lost! Interventions like breastfeeding, skin-to-skin contact, and in some cases microbial seeding (vaginal swabbing) can help support gut development after a C-section.

The Gut-Brain Connection

Your child’s brain and gut are in constant communication via the gut-brain axis. This network of nerves, hormones, and microbes plays a powerful role in regulating:

• Mood and emotional resilience
• Cognitive development and focus
• Conditions like autism spectrum disorders, PANS, and PANDAS

However, not all is lost! Interventions like breastfeeding, skin-to-skin contact, and in some cases microbial seeding (vaginal swabbing) can help support gut development after a C-section.

The gut and brain are in constant communication through nerves (especially the vagus nerve), hormones, and chemical messengers like neurotransmitters. Surprisingly, the gut is often referred to as the “second brain” because it produces many of the same neurotransmitters that the brain does.

For example:

• Serotonin – about 90% is made in the gut; it regulates mood, sleep, and focus
• GABA – helps calm the nervous system
• Dopamine – impacts motivation, attention, and learning

When the gut microbiome is healthy and diverse, it supports balanced brain chemistry. When it's out of balance (due to poor diet, stress, or illness), it can contribute to mental and emotional challenges.

📚 How Gut Health Impacts Learning and Emotional Well-Being

1. Mood Regulation

• A healthy gut supports the production of neurotransmitters like serotonin and dopamine.
• Imbalanced gut bacteria are linked to anxiety, irritability, and depression—even in children.

2. Focus and Attention

• Dysbiosis (microbial imbalance) may contribute to ADHD-like symptoms such as poor concentration and impulsivity.
• Inflammation in the gut can lead to neuroinflammation, which affects attention span and executive function.

3. Behavioral and Developmental Disorders

• Children with conditions like autism spectrum disorders (ASD) often show signs of gut dysfunction (e.g., constipation, diarrhea, food sensitivities).
• Research has found links between gut microbiota imbalances and PANS/PANDAS, which can cause sudden shifts in mood, OCD-like behaviors, and tics.

4. Stress Response

• A disrupted gut can lead to an overactive stress response (more cortisol), affecting emotional regulation, resilience, and even sleep quality.
• Stress itself can damage gut integrity, creating a cycle of gut-brain imbalance.

5. Cognitive Development and Memory

• Good bacteria help reduce inflammation and increase levels of brain-derived neurotrophic factor (BDNF), which is essential for learning and memory.
• Gut inflammation and poor nutrient absorption can impair cognitive development, especially in critical early years.

Top Kids’ Gut Health Strategies

Unfortunately, modern lifestyles can disrupt our digestive system. Common threats include:

• Sleep disturbances 
• Sedentary lifestyle habits 
• Lack of sun exposure or vitamin D 
• Processed and sugary diets 
• Overuse of antibiotics 
• Limited time outdoors 
• Poor food quality / GMOs

The good news? Most of these contributing lifestyle factors are within your control as parents!

STRATEGY #1 – Get Tested

Test, don’t guess! Know for sure what is going on in the gut through our GI Map and other stool testing.  These tests show the balance of the four microbes (parasitic, bacterial, fungal, yeast) plus other inflammatory markers to better understand what to:

• Remove
• Replace
• Repair
• Repopulate
• Rebalance

STRATEGY #2 – Feed a Healthy Microbiome

Boosting your child’s gut health starts with feeding the good microbes. This includes:

Prebiotics – These are plant fibers that act as food for beneficial bacteria. Top sources: green bananas, oats, apples, onions, garlic, asparagus, whole grains.

🌈 Eat the Rainbow – Different colors = different beneficial nutrients, fibers and bacteria.

Probiotics – These are live, helpful microbes. Top sources: yogurt with live cultures, kefir, miso, and sauerkraut.

Probiotics are especially helpful during or after antibiotics, illness, or stressful periods.

** PRO TIP - Eating in a relaxed state is super important.  Digestion is a parasympathetic process (non-stressed state)

** PRO TIP - Remove food and environmental sensitivities

STRATEGY #3 - Outdoor, Active Play

Kids’ guts benefit from being active outdoors in the sunshine and dirt!  Being active keeps blood sugar stable, builds muscle, keeps bowels moving, and is a heart-healthy habit for life! 🏃‍♀️ Stay Active – Movement promotes good gut flora. 🌱 Outdoor Play – Exposure to dirt and nature builds diversity of microbes!  

STRATEGY #4 - Prioritize Sleep 😴 Sleep Habits – Consistent routines support microbial balance.

Our bodies detox and regenerate at night when we sleep.  A quiet, cool, dark room… allowing our kids to fall asleep on their own… keeping extra EMFs out of the room and having a consistent time for bedtime supports gut health! 

STRATEGY #5 - Supplement When Needed

When you need natural antibiotic options, allergy relief, immune support, better focus or learning support we got you covered with some of our favorite supplements at the RHM Pharmacy!!

As functional medicine practitioners there is a time and place for a therapeutic protocol for healing the gut and a maintenance protocol.  Restoring gut health can often be several months even up to a year of diligent protocol following that includes the 5 R Protocol highlighted above of:

• Remove (get tested to know what to remove)
• Replace (enzymes, nutrients, probiotics)
• Repair (leaky gut support)
• Repopulate (pre, pro and post biotics)
• Rebalance 

Start Small, Think Big

You don’t have to change everything overnight or try all five strategies at once. Pick a couple of manageable steps and build from there. Each positive change is a gift to your child’s present and future health.
