Dr. Shaun Segal on Gut Health and Immunity in Children
When it comes to maintaining children’s health, parents typically consider vitamins, vaccines, and washing hands. While all those are crucial, one strong component of a child’s health tends to go unappreciated: the gut. In the opinion of Dr. Shaun Segal, a prominent Johannesburg-based pediatrician, gut health is instrumental in determining how robust a child’s immune system is—and how effectively it works when confronted with sickness.
Science has revealed over the last few years that the gut does so much more than break down food. It’s a sophisticated system of bacteria, the gut microbiome, that regulates immunity, battles inflammation, and even influences mood. In this blog, Dr. Shaun Segal outlines his professional views on how the gut and immune system connect, and ways parents can support them naturally.
The Gut: More Than Digestion
The human gut is inhabited by trillions of bacteria, both “good” and “bad.” A healthy gut keeps the balance in line, allowing children to absorb nutrients, manufacture important vitamins, and purge waste efficiently. But as Dr. Shaun Segal says, the gut also does something even more remarkable: it educates the immune system.
About 70% of the immune cells in the body reside in the gut. These cells recognize what’s dangerous (such as viruses and bad bacteria) and learn how to act on them. That’s why Dr. Shaun Segal usually calls the gut “the body’s first line of defense.
When the gut microbiome is in balance and diverse, it can trigger the immune system to respond calmly and effectively. But when unbalanced—through sickness, a poor diet, stress, or excessive antibiotics—it can cause more infections, allergies, or digestive issues.
Typical Gut-Immunity Issues in Children
Kids are particularly susceptible to gut problems because their microbiome is still in the process of developing. Dr. Shaun Segal says that a few indications that a kid’s gut is out of whack include:
Recurrent colds or infections
Persistent digestive distress (constipation, bloating, or loose stools)
Food allergy or intolerance
Skin problems such as eczema
Loss of appetite or unusual weight loss
Difficulty concentrating or irritability
Although these symptoms do not necessarily mean that there is a gut problem, Dr. Shaun Segal advises us to pay closer attention if they are persistent, particularly if your child is “off” more frequently than normal.

How to Support Gut Health Naturally
The good news is, you don’t have to make radical changes to aid your child’s gut. Small, steady steps can be a big bonus in the long run, says Dr. Shaun Segal. Here are his top tips:
- Emphasize Whole, Fiber-Rich Foods
Fiber is food for the good bacteria in the gut. They use it to grow and keep the digestive system humming.
Dr. Shaun Segal suggests:
Fruits and vegetables (particularly berries, apples, carrots, and leafy greens)
Whole grains such as oats, quinoa, and brown rice
Legumes like lentils, chickpeas, and beans
Steer clear of highly processed snacks and fast foods, which destroy gut equilibrium and nourish bad bacteria.
- Add Probiotics and Prebiotics
Probiotics are “good bacteria” that help the gut. Prebiotics are the fibers that nourish them.
Dr. Shaun Segal recommends including:
Probiotic-rich foods: yogurt, kefir, pickles (naturally fermented), and tempeh
Prebiotic foods: bananas, onions, garlic, leeks, and asparagus
For finicky eaters or allergy-plagued children, probiotic supplements might be a solution, after a pediatrician has been consulted.
- Avoid Excess Antibiotics
Though antibiotics are crucial in combating bacterial infections, their excess can eliminate healthy gut bacteria as well.
Dr. Shaun Segal urges parents to reserve the use of antibiotics for truly necessary situations and to complete the course of treatment when they are used. Reconstitution of the gut through probiotic-laden foods afterward will restore equilibrium.
- Promote Outdoor Play and Physical Exercise
Nature exposure (dirt, animals, and fresh air) promotes the development of a more varied microbiome in children. Exercise also aids digestion and immune system function.
Dr. Shaun Segal suggests a minimum of one hour of active play each day, preferably outside. Bike rides, nature strolls, and backyard playtime all qualify.
- Reduce Stress and Prioritize Sleep
Stress—even in kids—can harm the gut. So can sleep deprivation.
Dr. Shaun Segal likes to remind parents that emotional health and digestive health walk hand-in-hand. Encouraging kids to deal with anxiety through everyday routines, soothing bedtime routines, and transparency helps both immunity and mental well-being.
When to See a Doctor
If your child is plagued by ongoing digestive problems, repeated infections, or shifts in energy, appetite, and mood, it might be time to consult a professional. Dr. Shaun Segal performs comprehensive evaluations to determine root problems and suggest effective, kid-friendly solutions that fit the family lifestyle.
He repeatedly insists that parents need to go with their gut: “If there’s something that doesn’t feel right with your child, it’s always a good idea to check in. You’re the one who knows them best.”
Conclusion by Dr. Shaun Segal
Healthy immunity begins in the belly, not with a pill. In the opinion of Dr. Shaun Segal, supporting children’sdevelopmentg a healthy gut is one of the most effective, natural methods of maintaining their overall health in the long term.
It doesn’t need to be complicated. With whole food, movement, rest, and a little bit of dirt, you can fortify your child with resilience from the inside out. And if, along the way, you ever need some guidance, your pediatrician will be there for you.
Because, as Dr. Shaun Segal always says,s: “Healthy kids start in the gut—but they thrive with support.”
