The gut-immunity connection: How to strengthen your child's defences from the inside out

Gut health has become all the rage amongst us adults. We are realizing the important role our gut plays in our moods, energy, cravings, immunity and overall well-being. Does the same thing apply to our kids? Yes, in fact it does, especially when it comes to immunity.We spend so much time trying to build our child’s immunity, without realizing one of the key pieces is looking at their gut health. Around 70% of the immune system lives in the gut. The gut, which is majorly found in the large intestine, is home to the body’s largest ecosystem of billions of microorganisms. This community is what is responsible for helping us digest and absorbing nutrients, training the immune system, fighting off invades, affecting our moods and behaviour. The gut is also known as the second brain as it communicates constantly with the brain. When you have a thriving gut, your body is able to support strong immunity, regulate emotions, absorb nutrients from food and help your overall well-being. If it is inflamed or imbalanced, the consequences can show up- with regular cold and coughs, allergies, eczema, major tantrums, poor focus, tummy troubles. Today, 1 in 5 kids have eczema. Hippocrates stated that all diseases start in the gut. For kids, their gut is still developing and we can use this time to really help it flourish. From the time of conception till 2.5 years old, their gut changing rapidly. That is why the first 1000 days lays the foundation for future brain, immune, physical, and behavioral system. Babies born vaginally get first immunity-boosting microbes from the birth canal. C-section babies lack this, which can lead to weaker immunity early in life. Early and long skin-to-skin contact and starting breastfeeding can help. A baby’s gut bacteria is determined by mom’s gut health in utero, gestational stage, mode of delivery, diet, and antibiotic use.The reason gut health is so important is because it helps with nutrient absorption. If their gut is not thriving, then no matter what you feed them, they won’t be able to get the nutrition from it, which then in turn gives them the vitamins and minerals they need for growth and immunity. Another important reason for gut health is elimination. When the gut is not working optimally, the body is not able to release waste and toxins and it can get accumulated, putting extra strain on immunity. Also, if your struggling with a picky eater, it can be related to their gut health. Gut bacteria influence taste receptors and signals the brain to crave certain foods and be okay to accept certain foods. A healthier gut often leads to wider food acceptance and less fussiness. The gut also produces 90% serotonin- the happy chemical, so this can also affect your child’s moods. If you are noticing your child is constantly having tantrums, it can be realted to their gut health.Here are simple, everyday ways to support your child’s gut to help boost their immunity:A nourished gut helps support a stronger immune system, better moods, and a healthier future.
