As National Nutrition Week puts the spotlight on healthy eating and the role of nutrition in overall wellbeing, parents may also be wondering how the food on their child’s plate can support their immune health. With children often experiencing recurring coughs, colds and infections, experts say the answer does not lie in a single “immunity-boosting” food or expensive supplement. Instead, a balanced diet that provides a range of essential nutrients, along with adequate sleep, hydration and physical activity, can help build a strong foundation for healthy growth and immune function.
According to Dr Chitra BK, Chief Dietitian, KIMS Hospitals, Electronic City, Bengaluru, the focus should be on the child’s overall diet rather than individual foods marketed as immunity boosters. “A child’s immune system depends more on the diet as a whole than on a single ‘immune booster’ food. Parents must concentrate on offering a balanced meal, which contains sufficient protein, fats, vitamins, minerals and fibre for development as well as immune response in children,” she says.
Why Micronutrients Matter For Children’s Immunity
A child’s immune system requires several vitamins and minerals to function normally. Inadequate intake of essential micronutrients can affect growth as well as the body’s ability to mount an appropriate immune response.
Vitamin D plays an important role in immune function and respiratory health. Some infants may require vitamin D prophylaxis, while older children with limited sun exposure may need supplementation when recommended by a healthcare professional.
Vitamin C is an antioxidant that supports immune-cell function and the body’s protective barriers. Citrus fruits, guava, amla and bell peppers are useful dietary sources.
Zinc is required for the development and functioning of several immune cells, including neutrophils and natural killer cells. Nuts, seeds such as pumpkin seeds, legumes and eggs can contribute to zinc intake.
Vitamin A helps maintain the integrity of mucosal surfaces in the respiratory and gastrointestinal tracts, which form an important part of the body’s first line of defence. Carrots, sweet potatoes and leafy green vegetables are among the foods that provide vitamin A or its precursors.
Iron is also important for immune-cell development, while selenium supports antioxidant functions in the body.
Rather than focusing on individual nutrients in isolation, Dr Chitra recommends creating variety on the child’s plate. “Consuming different coloured fruits and vegetables, whole grains, pulses, milk and dairy products or their appropriate substitutes, eggs and other protein sources will allow children to take in the necessary array of nutrients,” she explains.
The Rainbow Plate Approach
One simple way for parents to increase dietary variety is to introduce foods of different colours across meals and throughout the week. Dr Ravi Malik, MBBS, MD (Paediatrics), MAMC, Founder & Medical Director, Malik Radix Healthcare (MRHC), says, “Red and purple foods such as berries and beetroot contain beneficial plant compounds, including anthocyanins. Orange and yellow foods such as carrots and oranges provide carotenoids and vitamin C, while green vegetables such as spinach and broccoli contribute nutrients including folate and other plant compounds.” The idea is not to make every meal complicated, but to expose children to a broad range of foods over time.
Protein deserves equal attention. Eggs, pulses, paneer, dairy products and lean meats can provide the protein children need for growth and for producing antibodies and other proteins involved in immune function.
A Healthy Gut May Also Support Immune Health
Nutrition and gut health are closely connected, making probiotics and prebiotics another consideration when planning children’s meals. Dr Ravi Malik says, “Probiotics are beneficial microorganisms found in foods such as curd and yoghurt, while prebiotics are types of dietary fibre that help nourish beneficial gut bacteria. Oats, vegetables, fruits and legumes can provide prebiotic fibres.”
“A good gut condition needs to be maintained as the gut microbiome is essential in maintaining the health of an individual,” adds Dr Chitra. She recommends including probiotic foods such as curd or yoghurt along with prebiotic-rich foods such as oats, vegetables, fruits and legumes.
At the same time, parents should pay attention to what children are consuming less of. Sugary beverages and frequently consumed unhealthy snacks can displace more nutritious foods from the diet.
Immunity Is Not Just About Food
While nutrition is an important part of children’s health, Dr Ravi Malik, stresses that parents should look at the bigger picture.
“Supporting children’s immunity involves a combination of adequate nutrition, healthy routines and sufficient recovery. Sleep is particularly important for children’s growth and development, while adequate water intake supports normal bodily functions. Regular age-appropriate physical activity also contributes to overall health and fitness,” he adds.
This means that a nutritious lunch cannot compensate for consistently inadequate sleep, just as an active child may still need a balanced diet to meet their nutritional requirements.
Should Parents Give Immunity Supplements?
The growing popularity of “immunity boosters” and children’s superfoods can make it tempting for parents to add supplements to their child’s routine. However, experts caution against giving supplements unnecessarily.
“Parents need to avoid giving unnecessary supplements or superfoods, as they have not been recommended by a medical practitioner,” says Dr Chitra.
If a child has a restricted diet, poor appetite, concerns about growth, or a suspected nutritional deficiency, parents should discuss their individual nutritional needs with a paediatrician or qualified healthcare professional before starting supplements.
