Understanding How Your Baby’s Gut Health Influences Growth

As a mom, you want your baby to grow strong and healthy. But did you know that your baby’s gut plays a huge role in their growth? The bacteria in your baby’s tummy make a favorable environment to absorb nutrients, gain weight, and develop properly.

Let’s explore how a healthy gut supports your baby’s growth, especially in the early months of life.

The First Gut Bacteria: A Foundation for Growth

From birth, your baby’s gut is home to billions of bacteria, both good and bad. In a healthy state of body, these good & bad bacteria exist in a balance. Imbalance between these results in a diseased state. A baby’s gut bacteria change a lot during the first 2-3 years of life towards a diverse and stable microbiota, mimicking that of an adult.

Building a Resilient Gut: How Your Baby’s Microbiome Grows Beyond Birth 

Beyond birth, your baby continues to collect even more microbes from you, their caregivers, and their environment, all of which contribute to shaping their gut microbiome community. This community has an influence on the development of a strong and healthy digestive system, bone development, and brain development, laying the foundation for lifelong health. A balanced gut microbiome is key to optimal development. Here’s how:

1.  Nutrient Absorption

Breakdown of food happens in the gut. A balanced gut microbiome in the gut makes favorable conditions for the absorption of nutrients, which are essential for age-appropriate growth.^{1, 2}

2.  Supports Immunity

70-80% of immune cells are present in the gut. A healthy gut supports the optimal development and functioning of the immune system. ^{2, 3}

3.  Supports Brain Growth

The gut is also known as the second brain of the body. The brain and gut have a two-way communication through nerves and the gut microbiome ⁽³⁾.  The gut microbiome, through its communication with the brain, influences the mood and behavior of the baby.

4.  Digestion

A healthy gut and balanced gut microbiome reduces the probability of tummy troubles like colic, constipation, and diarrhea, keeping your baby comfortable and supporting their growth.³

Key Nutrients for Baby Gut Health & Growth

The key to a healthy gut is to ensure a balanced microbiome that supports the optimal development of the type of microbiome that sets the foundation for lifelong health. Providing the nutrients that support the optimal development and balance of microbiome, especially in early childhood, can make a difference.^{1, 3} Let’s explore the essential nutrients and feeding practices that will help your baby’s gut microbiome and support overall development:

1.  Breastfeeding: The Ultimate Superfood for Baby’s Gut & Growth

Breast milk is a powerhouse of essential nutrients, antibodies, and beneficial bacteria that support your baby’s gut health, immunity, and overall development. It provides probiotics and prebiotics that support digestion and the immune system and reduce the risk of infections, allergies, and long-term conditions like asthma.⁴ Even after introducing solids, breast milk remains a vital source to guide the optimal development of the gut microbiome, thereby supporting overall growth and well-being.⁵

2.  Introducing Complementary Foods: Fuelling Growth & Gut Health

At around 6 months, your baby’s nutritional needs expand, and it’s time to introduce solid foods. But what you feed them matters—not just for growth but for gut health, too! It is another milestone in the development of the gut microbiome. During this time, due to the introduction of solids, there is a shift in the balance of the gut microbiome. In some, this increases the probability of concerns like diarrhea and other tummy issues. Opt for gut-friendly, fiber-rich, and nutrient-dense foods that help cultivate a healthy gut microbiome. Early exposure to a variety of healthy foods shapes your baby’s gut bacteria and sets the stage for a lifetime of overall health.⁶

3.  The Power of Probiotics & Prebiotics: Supporting Baby’s Gut Health

A healthy gut thrives on a balance of good bacteria and bad bacteria.  Probiotics (good bacteria) like L. reuteri and prebiotics (food for good bacteria) like FOS/GOS together help maintain the balance and modulate the gut microbiome to support gut health.⁴

Your baby’s gut health is the foundation for lifelong wellness. By nourishing their gut with the right foods like prebiotics & prebiotics ——you can support the optimal development of digestion, immunity, and brain development. Remember, all is well when the Gut is well!
