As a parent, ensuring your toddler stays strong and healthy is a priority. While their immune system develops and adapts as they get exposed to new foods and environments, optimal nutrition also plays a key role. A balanced diet, fortified milk, and essential nutrients are tools to support their developing immunity and thereby support overall growth.1

Let us explore the role of nutrition in supporting your child’s immune function and how you can support their development through fortified foods/ milk and healthy lifestyle choices.

Factors That Influence Your Toddler’s Immune System

Here are some factors that influence the functioning of your child’s immune system:2

  • Poor Nutrition – Deficiencies in essential vitamins (A, C, D) and minerals like zinc and iron can negatively impact immunity.
  • Lack of Sleep – Insufficient rest negatively influences your body to fight infections.
  • Germ Exposure – Exposure to unhygienic conditions and harmful contaminants can weaken the immune system and increase the risk of infections.
  • Lack of Physical Activity – Limited physical activities or lack of general exercise may affect overall growth and degrade the immune system.
  • Irregular Vaccination- Missing regular and timely vaccination can make toddlers vulnerable to preventable infections.

While you cannot control every factor, you can ensure your child receives proper nutrition, a hygienic environment, and timely vaccination per the Indian Academy of Pediatrics (IAP) schedule to support their immune health.4

 

Nutrition is a Foundation to Support the Immune System's Function

Nutrients play an important role in supporting the immune function. A well-nourished toddler is better equipped to resist infections and recover quickly from illnesses.

  • Vitamins & Minerals Matter: Vitamins A, C, D, E, B6, B12,  zinc, iron, selenium, and magnesium all help support your toddler’s immune system.5
  • Healthy Fats Are Key: Omega-3 fatty acids are also important for supporting immune health.6
  • Balanced diet: A mix of fruits, vegetables, whole grains, proteins, and healthy fats forms the basis of a strong immune foundation.
