How Parents Can Help Strengthen Their Toddler’s Immunity?
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.
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 from illnesses.
- Vitamins & Minerals Matter: Vitamins A, C, D, E, B6, and B12, zinc, iron, selenium, and magnesium all help support your toddler’s immune system.(3)
- Healthy Fats Are Key: Omega-3 fatty acids are also important for supporting immune health. (4)
Did You Know?
Nutrient deficiencies can directly impact how your toddler’s immune system functions. A diet deficient in key vitamins and minerals may result in weakened immunity, slower growth, and increased susceptibility to illness. Fortified foods, and fortified milk, support in bridging the nutritional gaps!
Fortified Milk: A strategy to support Immune Health
While a balanced diet is key, fortified milk/foods provide a sustainable strategy for providing essential nutrients. How?
- Bridge the nutrient gap – Fortified milk provides added vitamins and minerals. These support immune development, brain function, and strong bones.
- Calcium & Vitamin D for supporting the development of Bones & Immune function not only strengthens teeth and bones but also play a crucial role in immune function.
- Iron supports cognitive development and zinc helps in preventing the risk of infections. (5)
- Convenient & Easy to Include – For fussy eaters, fortified milk along with a balanced diet can easily help in completing their nutritional needs.
Pro Tip: Look for fortified toddler milk which has nutrients like calcium, vitamin D, iron, and zinc. These nutrients are known to support immune function and thus overall growth. However, it is always recommended to take advice from your pediatrician to make the right choice.
